What Is RF Microwave PCB?

RF Microwave PCB is a specialized circuit board designed for carrying and processing high-frequency signals, typically covering radio frequency (RF) from approximately 300 kHz to 300 GHz and microwave frequencies from 1 GHz to 300 GHz.

Unlike conventional PCBs, it utilizes high-frequency substrate materials such as Rogers, Teflon, or ceramic-filled composites. These materials feature extremely low signal loss, stable dielectric constant, and excellent thermal performance. Its design and manufacturing are highly precise, emphasizing signal integrity through exact control of trace impedance, optimized transmission line structures like microstrip and stripline, minimized parasitic effects, and strict regulation of laminate processes and surface treatments. This ensures efficient, low-distortion, and low-interference transmission of high-frequency or microwave signals on the board.

Why Choose RF Microwave PCB?

Benefits of RF Microwave Printed Circuit Board:

RF Microwave PCB Board Design & Layout

1. Substrate Selection and Characteristic Matching

Material Expansion Selection: For high-frequency scenarios, recommend Rogers RO4350B, Taconic TLX series; for high-precision scenarios, select Panasonic Megtron 6 (Dk=3.3±0.05, loss＜0.002@10GHz) or Isola I-Tera MT40 (Dk=3.45, loss＜0.003@5GHz). FR-4 is limited to low-frequency test boards or cost-control scenarios, requiring gold-plating/immersion silver to reduce surface roughness impact.
Dynamic Parameter Verification: Use Agilent 85070D Dielectric Constant Tester to measure Dk values, combined with temperature-humidity aging tests to verify long-term stability. Thickness tolerance control requires collaboration with substrate supplier capabilities (e.g., ±5% high-end substrates), and design margin is increased to 25% to address processing errors.
Special Scenario Adaptation: Millimeter-wave (＞30GHz) applications recommend Liquid Crystal Polymer (LCP) substrate (Dk=3.0, loss＜0.0015), paired with microvia arrays for ultra-low loss transmission.

2. Precise Impedance Control and Verification

Multidimensional Calculation Verification: Cross-validate using Polar SI9000 and Altium Designer 2D/3D impedance calculators. For non-standard impedances (e.g., 75Ω video signals), optimize line width/dielectric thickness combinations via Taguchi method to ensure process window ≥±3mil.
TDR In-Depth Application: Set reference planes near TDR test points, measure single-ended/common-mode impedance via differential probes, and synchronously verify signal integrity metrics (rise time＜20ps). For high-speed digital-RF hybrid circuits, use eye diagram instruments to validate timing margins.
Differential Pair Optimization: For serpentine differential pairs, validate bending radius impact on impedance via electromagnetic simulation, ensuring length matching error＜0.5mil@10GHz.

3. Stack-Up Structure Optimization Design

Multilaminate Expansion Scheme: 8-layer boards recommend “Signal-GND-Power-Signal-Power-GND-Signal-Signal” structure with dual GND layers in the middle for dual shielding. 4-layer boards are only suitable for low-power RF modules, requiring blind/buried via technology for interlayer interconnection.
Interlayer Coupling Suppression: Insert low-dielectric isolation layers (e.g., Arlon AD300) between adjacent signal layers to reduce interlayer crosstalk＞20dB. Power-GND spacing is optimized via finite element analysis to ensure capacitance coupling＞90%.
Mixed-Signal Processing: For digital-RF hybrid circuits, use “island GND” technology to isolate digital noise, paired with beads/inductors to construct low-pass filter networks.

4. Signal Path Layout Specifications

Trace Process Refinement: Use tapered line width technology for smooth impedance transition (e.g., 50Ω to 75Ω) to avoid impedance discontinuity reflections. For microwave signals, adopt coplanar waveguide (CPW) structure with ground via arrays forming a continuous reference plane.
Via Optimization Design: Laser microvia technology achieves 0.1mm microvias, paired with back-drilling to eliminate stubs. High-frequency vias require parasitic parameter verification via Ansys Q3D to meet design thresholds.
Shielding Structure Upgrade: Set electromagnetic shielding walls around critical signal paths, using nickel/gold plating to enhance shielding effectiveness. For radiation-sensitive devices, use shielding covers + thermal gel composite heat dissipation solutions.

5. Grounding and Shielding Strategies

Hybrid Grounding Enhancement: Low-frequency modules use “star grounding” to the main ground terminal; high-frequency modules use “mesh grounding” to reduce ground bounce noise. RF front-end modules adopt “GND-Signal-GND” sandwich structure for dual shielding.
Shielding Effectiveness Verification: Use EMxpert near-field scanner to measure shielding effectiveness＞60dB@1GHz. Sensitive devices require 3D electromagnetic simulation to validate shielding structure effectiveness.
Ground Via Arrays: Adopt “honeycomb” via array layout with spacing≤λ/20@operating frequency to form a continuous Faraday cage. Vias require plating fill technology to enhance reliability.

6. Power Integrity Optimization

Decoupling Capacitor Strategy: “0.01μF high-frequency + 10μF low-frequency” capacitor combinations paired with beads to construct multi-stage filter networks. Power noise-sensitive devices use embedded capacitor technology (e.g., buried capacitor layers).
PDN Simulation Enhancement: Use Ansys SIwave for full-wave electromagnetic simulation to verify PDN impedance＜0.5Ω@3GHz. High-frequency power noise uses power plane segmentation + capacitor bridging technology.
Power Plane Optimization: Mesh copper pour enhances current carrying capacity, paired with thermal vias for thermal-electrical co-design. Power planes are validated via voltage drop simulation to ensure drop＜3%.

7. Thermal Management and Heat Dissipation Design

Heat Dissipation Structure Upgrade: High-power devices use “thermal pad + thermal via + heat sink” three-tier cooling solutions, paired with thermal interface materials to achieve thermal resistance＜5℃/W. Millimeter-wave devices use diamond heat sink substrates.
Thermal Simulation Verification: Use Ansys Icepak for thermal simulation to validate hotspot temperature＜85℃. For high-density layouts, use thermal-electrical-structural co-simulation to ensure thermal stress＜material yield strength.
Copper Thickness Selection: Top/bottom layers use 3oz copper for enhanced thermal diffusion; inner layers use 1oz copper to balance cost and performance. Extreme environment applications use gold-plating/immersion silver for corrosion resistance.

8. Design for Manufacturability and Testability

DFM Check Expansion: Includes line width uniformity, pad size consistency, minimum annular ring verification, etc. Use Valor NPI software for automated checks to meet IPC-6012 standards.
Test Point Deepening Design: Use 50Ω SMA interfaces paired with calibration kits for precise testing. High-speed digital signals use differential test points paired with eye diagram instruments for timing validation.
File Delivery Expansion: Includes complete Gerber files (impedance layer, pad layer, silkscreen layer, stencil layer) paired with process specification documents (back-drill depth, blind/buried via positions). Use Git version control for document traceability.

9. Simulation Verification and Document Delivery

What Is PCB Dielectric Thickness?

PCB dielectric thickness refers to the vertical distance of the insulating material between adjacent conductive layers, such as signal layers, power planes, or ground planes, typically measured in millimeters (mm). It is a critical parameter in PCB stackup design, directly impacting electrical performance (e.g., impedance control, signal integrity) and mechanical stability.

Industry standards generally recommend a minimum dielectric thickness of 0.1mm to prevent voltage breakdown, while emphasizing symmetric design principles, including consistency in dielectric material type, copper foil thickness, and pattern distribution to ensure board reliability.

Common PCB Dielectric Thickness

Single-Sided PCBs

Thickness Range: 0.2mm (8mil) to 1.6mm (63mil), with 1.0mm (39mil) being most common for cost-sensitive applications.
Design Rules: Minimal dielectric thickness ≥0.1mm to prevent voltage breakdown; no symmetry requirement due to single conductive layer.
Applications: Simple control circuits, LED displays, and entry-level consumer electronics.

2 Layer PCBs

Thickness Range: 0.2mm (8mil) to 1.6mm (63mil), with 1.0mm (39mil) and 1.6mm (63mil) dominating industrial/consumer markets.
Features: Symmetric dielectric layers (e.g., 0.8mm core + 0.1mm prepreg on each side) ensure mechanical stability; supports through-hole vias.
Applications: Power supplies, automotive electronics, and mid-complexity control systems.

4 Layer PCBs

Stack-Up Example: Top/bottom signal layers (0.5mm core each), inner power/ground layers (0.2mm core), separated by 0.1mm prepreg. Total thickness ≈1.0mm.
Performance: Balanced signal integrity via controlled impedance (e.g., 50Ω microstrip lines) and reduced crosstalk; symmetric design minimizes warpage.
Applications: Smartphones, IoT devices, and compact industrial controllers.

6/8-Layer and Higher Multilayer PCB

Thickness Allocation: Core layers (0.1mm–0.3mm), prepreg layers (0.05mm–0.2mm), with incremental layer addition. For example, an 8-layer board may use dual 0.2mm cores + multiple 0.1mm prepregs.
Advanced Design: High-speed/high-frequency applications adopt ultra-thin dielectrics (≤0.075mm) and low-loss materials (e.g., Rogers RO4003C at 0.1mm) for RF/5G modules.

IPC Standard for PCB Dielectric Thickness

Standard Thickness (mm)	Tolerance (±%)	Impedance Board Tolerance Standard	Applicable IPC Standard
0.8	10%	IPC-4101C/M Grade	IPC-4101 Series
1.0	10%	IPC-4101C/M Grade	IPC-6012B
1.2	10%	IPC-4101C/M Grade	IPC-600G
1.6	10%	IPC-4101C/M Grade	IPC-2221A
2.0	10%	IPC-4101C/M Grade	IPC-A-600

Surface Microstrip Line: Z₀ = 87 / √(εᵣ + 1.41) × ln[5.98h / (0.8w + t)] , applicable to unshielded outer signal layers.
Inner Layer Stripline: Z₀ = 60 / √εᵣ × ln[4h / (0.67π(0.8w + t))], requiring symmetric dielectric thickness on both sides.
Differential Pair Impedance: Z_diff = 2Z₀(1 – 0.347e^(-2.9B/B)), where B=s/(s+w) and s denotes line spacing.
Effective Dielectric Constant Correction: ε_eff = (εᵣ + 1)/2 + (εᵣ – 1)/2 × [1/√(1 + 12h/w)], accounting for dispersion effects at high frequencies.
Edge Effect Compensation: Effective line width W_eff = w + 1.1t×(εᵣ+0.3)/√ε, corrects for trapezoidal cross-sections post-etching.

Enhanced Calculation Process:

Target impedance grading: 50Ω ± 10% for single-ended lines, 90Ω ± 8% for differential pairs, 75Ω ± 5% for RF millimeter-wave lines.
Material parameter refinement: FR-4 exhibits ε_r = 4.5–4.8 at 1GHz, while high-frequency materials like RO4350B show ε_r = 3.66 ± 0.05 at 10GHz.
Copper thickness calibration: 1oz copper measures 35μm ± 2μm, with etching factor ~0.8 accounting for sidewall taper.

How to Calculate PCB Dielectric Thickness?

How to Measure PCB Dielectric Thickness?

A guide to how to measure PCB dielectric thickness:

1. Destructive Measurement

Cross-section Analysis (Metallographic Microscopy)

Steps: Cut PCB sample → Epoxy resin embedding and curing → Grind and polish cross-section → Enhance contrast with staining → Measure interlayer thickness under microscope.
Accuracy: ±1 μm, enables simultaneous analysis of copper thickness, dielectric uniformity, and hole wall quality.
Limitations: Permanent sample damage, time-consuming (2–4 hours per sample).

Mechanical Layer Peeling + Micrometer Measurement

Operation: Peel PCB layers sequentially → Measure separated dielectric layers directly with digital micrometer.
Applicable: Thicker dielectrics (e.g., FR-4 core), scenarios without extreme precision requirements.
Note: Peeling may cause dielectric layer tearing, affecting measurement accuracy.

2. Non-destructive Measurement

Laser Thickness Gauge

Principle: Laser triangulation/interferometry, calculates thickness via optical path difference.
Advantages: Accuracy ±0.5 μm, supports 0.15–0.25N micro-pressure contact to prevent board deformation, measures local areas of multilayer boards (e.g., under impedance lines).
Typical Equipment: Oxford CMI series (95% industry coverage), integrates micro-resistance (SRP-4) and eddy current (ETP) technologies for simultaneous copper thickness measurement.

X-ray Fluorescence (XRF)

Application: Irradiate copper-clad laminate with X-rays → Analyze characteristic X-ray energy/intensity → Derive dielectric thickness (requires known material composition).
Automation: Regional scanning with 100+ measurement points per area, SpecMetrix system achieves <1μm error (vs. cross-section method).
Applicable: Batch testing of uniform dielectric layers, thin-layer (<30μm) HDI boards.

Flying Probe Tester (Indirect Calculation)

Principle: High-voltage probes (4–8 pins) test insulation resistance → Calculate thickness via known dielectric constant (Dk) model (Formula: H ∝ ln(insulation resistance)/Dk)
Advantages: No fixture required, supports 0.2mm micro-pitch testing, suitable for high-density boards
Limitations: Relies on Dk value accuracy (may drift in millimeter-wave bands)

3. High-Frequency Specialized Methods (Millimeter-Wave/5G Scenarios)

RF Resonance Method

Steps: Fabricate dielectric resonator → Input swept-frequency signal → Capture resonance frequency shift → Calculate thickness and Dk via electromagnetic equations
Advantages: Non-destructive, frequency coverage up to 110GHz (5G millimeter-wave)
Key: Requires temperature-humidity calibration (moisture absorption affects Dk)

Terahertz Time-Domain Spectroscopy (THz-TDS)

Principle: Terahertz pulse penetrates dielectric → Measure reflection/transmission signal time difference → Calculate thickness (H = c·Δt/(2·Dk))
Applicable: Ultra-thin dielectrics (≤10μm) such as Anylayer HDI boards

4. Method Selection Guide

Scenario	Recommended Method	Accuracy	Speed	Destructive
R&D Validation/Failure Analysis	Cross-section Analysis	±1 μm	Slow	Yes
Mass Production Monitoring	Laser Gauge/XRF	±0.5 μm	Fast	No
High-Density Board Electrical Performance Evaluation	Flying Probe Tester	Indirect Calculation	Medium	No
Millimeter-Wave Material Characterization	RF Resonance Method	Model-Dependent	Medium	No

5. Measurement Considerations

Process Compensation: Dielectric shrinkage rate ~5–10% (FR-4) post-lamination, requires design margin; electroplating copper thickening (Formula: Copper Thickness = Current Density × Time × 1.83/100) compresses dielectric space
Environmental Control: Humidity rise may cause Dk shift ±0.2, affecting resonance/THz accuracy
Copper Foil Roughness Interference: At high frequencies, skin effect amplifies rough surface impact, artificially increasing dielectric “effective thickness”

How to Measure PCB Dielectric Thickness?

Dielectric Thickness PCB Design Considerations

Impedance Control Deepening:

In differential pair design, dielectric thickness must precisely match differential impedance (typically 90-120Ω). Taking USB3.0 as an example, a 0.15mm dielectric thickness with 8mil trace width/spacing achieves 90Ω differential impedance, while a 0.2mm thickness requires adjusting trace width to 6mil to maintain the same impedance. Polar SI9000 simulation shows that ±10% thickness deviation leads to impedance deviation exceeding ±7%, necessitating ±3% tolerance control via lamination process.

Signal Integrity Advancement:

At high frequencies, the impact of dielectric loss tangent (Df) becomes significant. FR-4 has a Df of ~0.018, resulting in 0.3dB/cm loss at 10GHz; whereas Rogers 4350B, with Df of 0.003, reduces loss to 0.05dB/cm at the same frequency. For 5G millimeter-wave designs (28GHz), 0.08mm PTFE substrate reduces insertion loss by 30% but requires increased glass fiber density to prevent dielectric constant fluctuations.

Lamination Symmetry Engineering Practice:

A typical symmetric 8-layer stackup is: Top layer – 0.05mm dielectric – Ground plane – 0.2mm dielectric – Power plane – 0.05mm dielectric – Bottom layer. This structure matches CTE (coefficient of thermal expansion), limiting warpage to 0.5%. Asymmetric designs, such as 0.3mm dielectric used unilaterally, cause Z-axis CTE differences exceeding 50ppm/℃, risking pad cracking.

Voltage Withstand & Insulation Enhancement:

For IGBT driver boards, 0.4mm PPO substrate withstands 1.2kVrms voltage, and with 2mil copper foil achieves 10kV breakdown voltage. Edge effects require chamfering (R≥0.5mm) and potting compound (εr=3.5) to reduce field strength by 40%, meeting UL94V-0 flame retardancy.

Thermal Management Synergy Design:

In power modules, 0.3mm thermal substrate (e.g., T410) with 2oz copper thickness controls thermal resistance at 0.8℃/W. Combined with thermal via arrays (50 vias/cm² density), junction temperature reduces by 20℃. CTE matching must be ensured to avoid thermal stress cracking from copper-substrate differences.

Mechanical Stability Enhancement:

Aerospace PCBs require vibration resistance >20G. Using 0.5mm substrate with back-copper reinforcement raises natural frequency to 120Hz, exceeding typical vibration spectra (5-100Hz). Finite element analysis (FEA) optimizes stiffener layout, reducing stress concentration by 50%.

Material Availability & Cost Control:

Standard FR-4 thickness (0.1-0.2mm) shows 15% cost variance, while 0.08mm ultra-thin substrate requires customization, extending lead time by 3 weeks. Hybrid stackups (e.g., 0.2mm FR-4 + 0.1mm high-speed material) balance performance and cost but require attention to lamination temperature differences to prevent delamination.

Manufacturing Process Limit Breakthrough:

mSAP technology achieves 0.05mm dielectric thickness with ±2% tolerance, requiring vacuum laminators (±1% pressure accuracy) and optical inspection (1μm resolution). For HDI designs, 0.03mm dielectric uses laser microvias (50μm diameter) with electroplated fill to ensure reliability.

Dielectric Thickness PCB Design Considerations

How Does Dielectric Layer Thickness Affect PCB Performance?

Signal Integrity and Impedance Control

Impedance Matching: Dielectric thickness directly affects transmission line characteristic impedance (e.g., 50Ω microstrip). A 10% thickness increase can reduce FR-4 material impedance by ~5%, causing signal reflections or losses. For example, a 1.6mm board vs. 1.0mm board with identical trace width shows ±12% impedance deviation, requiring trace width adjustment (e.g., 1.6mm board needs 0.01mm width reduction) for compensation.
High-Speed Signal Quality: In high-frequency (>5GHz) scenarios, thickness variations exacerbate signal delay and loss. At 10GHz, a 1.6mm board exhibits 33% higher loss (0.8dB/cm) than a 1.0mm board, impacting eye diagram opening (e.g., USB3.0 design requires strict thickness tolerance control).
Crosstalk and EMI: Thin dielectrics (e.g., 3-5mil) increase capacitive coupling between adjacent signal lines, raising crosstalk risk. Thicker boards reduce same-layer crosstalk by increasing layer spacing but require higher ground via density to prevent inter-layer crosstalk.

Thermal Management and Heat Dissipation

Thermal Conductivity Efficiency: Copper foil (385W/m·K thermal conductivity) serves as the primary thermal channel. Thick copper (e.g., 2oz) combined with 1.6mm substrate improves heat dissipation by 50%, reducing chip junction temperature (e.g., 20W chip junction temp drops from 83°C to 68°C).
Thermal Resistance Balance: Substrate thickness has an optimal range, 1.6mm boards show lower total thermal resistance (0.6°C/W) than 1.0mm (0.8°C/W). Beyond 2.0mm, substrate thermal resistance offsets copper gains, reducing effectiveness.
Uniformity and Reliability: Thick substrates (>1.6mm) enhance thermal capacity, slowing temperature rise and reducing hotspots (e.g., 60% smaller hotspot area), extending component life.

Mechanical Strength and Durability

Bending Resistance: Thick boards (≥1.6mm) offer higher mechanical rigidity, suitable for industrial/automotive applications requiring mechanical stress resistance. Thin boards (<1.0mm) are prone to bending, requiring stiffeners or flexible designs (e.g., polyimide substrates).
Thermal Expansion Matching: Z-axis CTE increases with thickness and must match components (e.g., ceramic chip CTE 5ppm/°C) to prevent solder joint cracking (e.g., 1.6mm board CTE 65ppm/°C outperforms 2.4mm board 75ppm/°C).

Manufacturing Process and Cost

Process Limitations: Ultra-thin dielectrics (<3mil) are challenging to manufacture, requiring prepreg materials for consistency. Thick boards need specialized lamination/drilling techniques, increasing costs.
Cost Tradeoffs: Thick copper and high-performance substrates (e.g., PTFE) improve performance but raise costs. Balancing signal integrity, thermal needs, and budget is essential.

EMC and Environmental Adaptability

Shielding Effectiveness: Thick boards enhance EMI suppression by increasing ground plane spacing, combined with 20H/3H principles (power plane inset 20H, signal line spacing 3H) to reduce edge radiation.
Environmental Tolerance: Thin boards are sensitive to humidity/temperature, requiring protective coatings. Thick boards offer better thermal stability in extreme temperatures but must avoid thermal stress-induced delamination.

How to Design A IC Board?

1. Requirement Analysis and Specification Formulation

Scene-specific demand refinement: For consumer electronics (e.g., smartphone main frequency ≥3GHz), industrial control (temperature resistance -40~125℃), automotive electronics (AEC-Q100 certification) and other scenarios, quantify specific indicators (e.g., power noise ≤2% VCC).
Standard and regulatory alignment: Clarify IPC-A-610 soldering standards, RoHS environmental requirements, EMC/EMI testing specifications (e.g., CISPR 25), and reserve design margins to address process fluctuations.

2. Architecture Design and Planning

Modular design strategy: Adopt IP core reuse (e.g., CPU soft core, DDR controller), define clear interface protocols (I2C/SPI/PCIe), and evaluate module-level power distribution (e.g., dynamic power proportion ≤70%).
Process-material-package collaboration: Select substrates based on signal rate (FR4 for ≤1GHz, PTFE/ceramic for high-frequency scenarios), match packaging forms (QFN/BGA), and verify thermo-mechanical reliability (e.g., CTE matching).

3. Circuit Design and Simulation

Mixed-signal design: Distinguish digital/analog regions, adopt isolation strips (≥3 times line width) to reduce crosstalk; analog circuits require separate power/ground planes and decoupling capacitor gradients (1μF+10nF).
Multidimensional simulation verification: Pre-simulation includes functional verification (Verilog-AMS models), timing analysis (setup/hold checks), signal integrity (eye diagram margin ≥20% UI); post-simulation incorporates parasitic parameter extraction (R/C/L) to verify actual delay ≤10% of clock cycle.

4. Physical Layout Design

Intelligent layout algorithm: Use automatic layout tools (e.g., Cadence Innovus) to optimize component positions, manually adjust critical paths (e.g., clock tree) to reduce delay; place thermally sensitive components (e.g., power transistors) near heat sinks and reserve thermal via arrays.
Wiring rule deepening: High-speed differential pairs (e.g., USB3.0) adopt equal-length routing (error ≤5mil), spacing ≥2 times line width; power plane segmentation avoids sharp angles, copper foil thickness ≥2oz for enhanced current capacity.

5. Layout Implementation and Verification

Advanced process adaptation: For processes below 28nm, adopt double patterning technology (DPT) to resolve lithography limits; incorporate dummy fills to improve uniformity and guard rings to suppress noise.
Multi-round verification closed loop: After DRC/ERC/LVS checks, perform power integrity analysis (IR-Drop ≤50mV), signal integrity review (reflection/crosstalk ≤5%); modify netlists via ECO if necessary and re-verify.

6. Post-Simulation and Parameter Extraction

Thermal-electrical coupling analysis: Use Ansys Icepak for thermal simulation, combine electrical parameters (e.g., on-resistance) to evaluate hotspot distribution; critical devices (e.g., MOSFETs) maintain junction temperature ≤125℃ with thermal allowance.
Reliability accelerated testing: Validate long-term reliability through high-temperature operating life (HTOL), temperature cycling (TC); package-level tests (e.g., solder ball shear force ≥10N) ensure mechanical strength.

7. Manufacturing File Output

Process file standardization: Generate manufacturing instructions including layer stack structures (layer thickness/material), impedance control tables, drilling parameters (hole diameter/tolerance), and confirm process capabilities (e.g., minimum line width/spacing) with foundries.
Supply chain full-process management: Establish BOM lists, audit supplier qualifications (e.g., ISO certification), plan SMT process parameters (temperature curves), and design test fixtures (e.g., JTAG interfaces) for mass production testing.

8. Testing and Validation

Multi-stage testing strategy: Prototype phase includes functional testing (e.g., I/O level verification), boundary scan (JTAG chain detection); mass production employs statistical process control (SPC) to monitor yield, and samples undergo environmental stress tests (e.g., 85℃/85%RH constant humidity).
Document digital archiving: Use PDM systems to manage design files (layouts/simulation reports), test data (eye diagrams/temperature rise curves), and change records, supporting traceability and iterative optimization.

IC Board Assembly Processes

1. Wafer Dicing and Selection

Dicing Technology Evolution: Mechanical blade dicing uses diamond-coated blades for wafers over 100μm, while laser dicing employs UV/IR lasers for contactless cutting of ultra-thin wafers (<100μm) and complex patterns. Post-dicing cleaning involves deionized water rinsing to remove silicon debris and UV exposure to reduce blue tape adhesion for easier die picking.
Die Selection Process: Utilizes vacuum suction or robotic arms with high-precision vision systems to select qualified chips, rejecting edge-defective dies. Yield control integrates AOI detection for real-time feedback.

2. Die Attach

Adhesive Systems: Conductive adhesives (e.g., silver paste) for high thermal conductivity applications, non-conductive adhesives for insulation, and solder pastes (Sn-Ag-Cu) for high-temperature reliability. Curing profiles match material properties—thermal curing at 175–185°C or UV curing for 90–120 seconds.
Precision Alignment: High-precision die bonders achieve ±0.05mm positional accuracy using dual-vision systems and pressure sensors to control bonding force, preventing chip damage.

3. Wire Bonding

Material Selection: Gold wires (20–30μm) for high-frequency reliability, aluminum wires for cost efficiency (lower strength), and copper wires with nitrogen protection for oxidation resistance. Bonding methods include thermosonic (gold) or ultrasonic (aluminum) techniques, ensuring bond strength ≥5g without non-stick bonds.
Process Optimization: Bonding parameters (force, temperature, time) are optimized via DOE experiments. X-ray inspection confirms void-free bonds, while SEM analyzes microstructural integrity.

4. Surface Mount Technology (SMT)

Solder Paste Printing: Stencil printing maintains solder paste thickness deviation ≤±15%, with SPI verification for uniformity. High-density PCBs use stepped stencils (0.03mm local thickening) to compensate solder volume.
Placement and Reflow: High-speed pick-and-place machines achieve 0201 component placement accuracy ±25μm. Reflow uses 10-zone nitrogen-protected furnaces, peak temperature 235–245°C for 40–60 seconds, monitored by thermocouples. AOI checks 11 solder joint criteria, with 3D detection for BGA shadow elimination.

5. Through-Hole Technology (THT)

Wave Soldering: Turbulent waves break through oxidation layers, while smooth waves form solder joints. Process parameters: 2–5 seconds at 240–260°C. Flux spray systems precisely control coating volume, and preheat gradients minimize thermal shock.
Lead Forming: DIP/PGA component leads are bent using precision dies to match PCB hole dimensions, with tolerance ≤0.1mm.

6. Encapsulation and Protection

Material Selection: Plastic molding (epoxy) for cost efficiency (limited thermal resistance), ceramic for high-frequency/high-power, and metal for optimal thermal conductivity. Underfill materials use capillary action to fill BGA gaps, eliminating thermal stress.
Process Refinement: Transfer molding pressure 10–20MPa, curing time 90–120 seconds. Vacuum degassing reduces encapsulation voids, with solder paste oxidation <1% for enhanced joint reliability.

7. Testing and Validation

Electrical Testing: ICT checks opens/shorts, flying probe tests cover high-density boards, and functional tests verify system performance. DC tests measure terminal voltage/current, while AC tests evaluate gain/distortion.
Reliability Testing: High-temperature/humidity (85°C/85% RH), thermal cycling (-40°C to 125°C), and vibration (5–2000Hz) screen for latent defects. AEC-Q standards apply to automotive electronics, supporting 2000V/200A high-power testing.

8. Quality Control Essentials

Statistical Process Control: SPC charts monitor solder paste thickness, placement accuracy, and soldering temperature. Process capability indices (Cp/Cpk) assess stability via Minitab visualization.
Traceability System: Batch records include wafer lot IDs, equipment parameters, and operator info, stored in cloud systems for 10-year traceability. ESD protection maintains workstation grounding resistance <1Ω.

9. Common Issues and Solutions

Solder Joint Defects: Reflow profile optimization with extended preheat and nitrogen protection reduces oxidation. Metallographic analysis ensures IMC layer thickness ≤5μm for reliability.
Die Warpage Control: Substrate warpage <0.75% using high-Tg materials. Vacuum degassing and <1% solder paste oxidation minimize voids.

10. Environmental Compliance

Lead-Free Processes: Compliant with RoHS using Sn-Ag-Cu solder (lead content <1000ppm). Waste management includes segregated recycling of solder dross and adhesive waste, with emissions treated via activated carbon adsorption and combustion.
Circular Economy: Metal/plastic waste repurposed into recycled products; agricultural waste converted to organic fertilizer or bioenergy for full lifecycle sustainability.

What Is Hermetic Ceramic Package?

A hermetic ceramic package is a special ceramic housing used to encapsulate high-reliability electronic components such as chips, sensors, and MEMS. Its core lies in the tight bonding between the ceramic substrate and a metallized sealing structure (such as a cover plate or pins), forming a completely sealed cavity that blocks the penetration of external gases and moisture. This hermeticity ensures that the internal sensitive components are protected from contamination and degradation under harsh environments (high temperature, humidity, corrosion), thereby achieving long-term stable operation of the electronic device.

What Are Types of Hermetic Ceramic Packages?

What Are Types of Hermetic Ceramic Package?

What Are Advantages of Hermetic Ceramic Packages?

Superior Hermeticity: Achieves absolute sealing via metal brazing or glass sealing processes, blocking moisture, dust, salt mist, chemical contaminants, and harmful gases. Internal environment controlled with dry inert gas (e.g., nitrogen) or vacuum for long-term stability.
Extreme Environment Reliability: Operates across -55°C to +200°C+ temperature range (varies by ceramic type). Withstands high-pressure/vacuum environments in deep sea, aviation, and aerospace. Radiation-resistant for space applications. Resists mechanical shock and vibration via high-strength ceramic housing.
Outstanding Material Properties: High insulation resistance (>10¹² Ω) prevents signal crosstalk and ensures safety for high-frequency/high-voltage devices. Thermal management via high-thermal-conductivity ceramics (e.g., AlN, 170-230 W/mK) efficiently dissipates chip heat. Low coefficient of thermal expansion (CTE) matches silicon chips to minimize thermal stress cracking. Chemically stable, corrosion-resistant, and oxidation-resistant.
Superior Electrical Performance: Low dielectric constant and loss reduce signal delay, enhancing performance for high-frequency/radio-frequency devices (e.g., 5G, radar). Stable parasitic parameters prevent environmental drift of capacitance/inductance. Metal lids provide electromagnetic interference (EMI) shielding.
Longevity and Durability: Decades-long lifespan in aerospace, medical implants, and other high-reliability fields. Ceramic materials avoid plasticizer evaporation, maintaining performance over time (superior to plastic packaging).
Multi-Functional Integration Adaptability: Supports high-density interconnection via HTCC/LTCC processes, integrating passive components (resistors/capacitors). Compatible with optical windows (e.g., laser packaging) and RF feedthrough structures. Adaptable to various high-reliability package formats (DIP, QFP, BGA, LCC).

What Are Applications of Hermetic Ceramic Package?

Satellites and Space Probes: Spacecraft control systems, onboard computers (radiation resistant, withstands drastic temperature changes in vacuum). High-precision sensors (e.g., gyroscopes, temperature sensors).
Missiles and Radar Systems: Missile guidance chips (resistant to supersonic flight vibrations and high temperatures). Phased array radar T/R modules (high-frequency signal stability requirements).
Avionics: Engine control units (ECUs), black box data recorders (shock resistant, fireproof).
Life Support Implantable Devices: Pacemakers, nerve stimulators (absolutely sealed to prevent bodily fluid corrosion, lifespan > 10 years).
Extracorporeal High-End Medical Devices: High-voltage sensors for MRI scanners, surgical robot control modules (electromagnetic interference resistant).
Deep-Sea Drilling and Oil & Gas Extraction: Downhole sensors (resistant to 200°C high temperature, 170MPa high pressure, and hydrogen sulfide corrosion).
