Copper thickness is a key factor that affects how your board performs. Choosing the right copper thickness is an important part of PCB design, it affects how well your circuit works, how long it lasts, and even how much it costs. In this blog, weâll break down why copper thickness matters, how to pick the right option for your PCB designââ to help you make informed decisions for your next project.
Why Copper Thickness Matters?
1. Current Carrying Capacity
Thicker copper layers handle higher currents without overheating. For example:
1 oz copper: Supports up to ~3A per 10mm trace width.
2 oz copper: Doubles the capacity to ~6A for the same width.
 Critical for power circuits like motor controllers or LED drivers.
3 oz+ Copper (140”m+):
Handles 12A+ per 10mm, suited for extreme applications like inverters or industrial power supplies. However, thicker copper increases fabrication costs and requires specialized manufacturing.
2. Signal Integrity
High-frequency designs (e.g., RF, 5G): Thinner copper (0.5 ozâ1 oz) with smooth surfaces reduces signal loss.
Standard circuits: 1 oz copper is sufficient for most low-frequency applications.
3. Durability
Thicker copper (â„2 oz) withstands thermal stress during soldering and mechanical wear in harsh environments.
Thin copper (0.5 oz) may crack under repeated vibration or temperature changes.
4. Cost Efficiency
Thicker copper increases material costs and requires longer etching times.
Based on our 19+years experiences in the PCB manufacturing field, today I would like to share you 6 Strategies How to Choose the Right Thickness
1. Calculate Current Requirements
Use the IPC-2152 standard or online tools (e.g., Saturn PCB Toolkit) to determine the minimum trace width and copper weight for your current.
Example: A 5A power trace with 1 oz copper needs a 2mm width. With 2 oz copper, the width drops to 1mm, saving space.
2. Prioritize Space vs. Performance
High-density designs: Use thinner copper (0.5 ozâ1 oz) to fit more traces.
Power-heavy boards: Option for 2 ozâ6 oz copper to reduce trace widths and avoid overheating.
3. Factor in Manufacturing Limits
Thin copper (0.5 oz): Prone to over-etching; requires tighter process control.
Thick copper (>3 oz): Needs specialized plating and etching, increasing lead time and cost.
Common Mistakes to Avoid
Ignoring Current Density: Thin traces with high current cause burnout.
Over-Designing: Using 3 oz copper for low-power signals wastes space and money.
Neglecting Manufacturer Feedback: Always confirm your fab houseâs capabilities (e.g., max/min copper weight).
Conclusion
Choosing the right copper thickness balances performance, cost, and manufacturability. By aligning your designâs needs with industry standards and manufacturer capabilities, you can avoid costly redesigns and ensure long-term reliability.

When creating modern electronic devices, every step matters â from the first sketch to the final product. If you’re exploring the process of printed circuit boards, or PCBs, this guide is your one-stop resource. Weâll walk through PCB design, fabrication, assembly, and testing, covering what engineers and buyers need to know. Whether you’re designing your first board or sourcing from a manufacturer, getting each step right ensures performance, reliability, and cost-efficiency.
What Is a Printed Circuit Board?
A printed circuit board (PCB) is the backbone of nearly all electronic systems. Itâs a flat board that holds and connects electronic components using conductive tracks, pads, and vias etched from copper sheets laminated onto a non-conductive substrate. Common materials include FR4, ceramic, aluminum, and polyimide.
PCBs come in many forms: single-sided, double-sided, and multilayer PCB, supporting everything from simple gadgets to complex military electronics. Their role is simple yet critical: provide physical support and reliable electrical connections.
How to Design a PCB Board?
The PCB design phase sets the tone for the entire lifecycle. It begins with defining the schematic, which maps out the electronic connections between components. Once thatâs ready, designers move to layout â placing components and routing traces.
Key steps include:
Creating schematics using software like Altium Designer, KiCAD, or Eagle.
Assigning footprints to components for proper placement.
Defining board dimensions, layer stack-up, and signal flow.
Routing signals with attention to trace width, impedance, and clearance.
Adding vias, copper pours, and power planes for optimal performance.
Design Rule Check (DRC) to verify spacing, trace width, and other constraints.
Generating Gerber files, which are the manufacturing blueprints.
Each design must balance space, power, heat, cost, and manufacturability. One overlooked detail could delay your entire project.
Considerations During PCB Design Phase
Designers must juggle multiple variables beyond schematic accuracy. Here are essential considerations to optimize performance and reduce failure risks:
1. Component Placement: Keep analog, digital, and power circuits separate to reduce interference. Group related components logically to minimize trace lengths.
2. Signal Integrity: For high-speed designs, impedance matching, differential pair routing, and minimizing crosstalk are vital.
3. Thermal Management: Use thermal vias, copper pours, and heat sinks to handle heat dissipationâespecially in power electronics.
4. Design for Manufacturability (DFM): Ensure trace width, drill sizes, and clearances match manufacturer capabilities.
5. EMC and EMI Compliance: Ground planes, shielding, and filtering components help meet regulatory standards.
6. Mechanical Constraints: Donât overlook mounting holes, connector alignment, or enclosure fit. These small details can turn into costly errors later.
Good design minimizes rework, improves lifespan, and lowers costs across production.
Full PCB Fabrication Process â Step by Step
Once the design is complete, the PCB fabrication process turns digital files into a tangible board. Hereâs how it happens:
1. Material Selection
The manufacturer selects base materials like FR4, aluminum, or ceramic depending on thermal, mechanical, and electrical requirements.
2. Inner Layer Imaging (for Multilayer PCBs)
Each inner copper layer is patterned with the circuit using photoresist, UV exposure, and etching techniques.
3. Lamination
The etched inner layers are stacked and laminated under heat and pressure, forming a solid multilayer structure.
4. Drilling
Holes are drilled to create vias for electrical connections between layers. Laser drilling is used for microvias.
5. Plating and Copper Deposition
Holes are plated with copper using electroplating to ensure conductivity across layers.
6. Outer Layer Imaging
Outer copper layers are patterned similar to the inner layers using photoresist and etching.
7. Solder Mask Application
A solder mask is applied to insulate the board and protect traces, leaving pads and holes exposed for soldering.
8. Silkscreen Printing
Component labels, logos, and reference indicators are printed on the board.
9. Surface Finish
A surface finish like HASL, ENIG, OSP, or Immersion Silver is applied to exposed copper pads to protect them and improve solderability.
10. Electrical Testing
Flying probe or bed-of-nails tests check for open circuits and shorts.
Common PCB Assembly Issues During Manufacturing
During PCB assembly, components are mounted and soldered onto the board. This phase can be manual or automated using SMT (surface-mount technology) and THT (through-hole technology).
But several issues can disrupt this process:
1. Tombstoning: A component lifts on one side during reflow, causing connectivity failure.
2. Solder Bridges: Excess solder connects two pins unintentionally, leading to short circuits.
3. Cold Joints: Poor soldering results in weak mechanical bonds and unreliable connections.
4. Misaligned Components: Incorrect placement, often caused by poor paste application or pick-and-place calibration.
5. PCB Warping: Thin or large boards may bend during reflow, affecting soldering and mechanical integrity.
6. Component Damage: Excessive heat or mishandling can destroy delicate ICs or capacitors.
Quality control, professional assembly lines, and well-prepared Gerber + BOM files help avoid these issues.
How to Test Printed Circuit Boards?
After assembly, PCB testing ensures the product works before final integration. There are several testing levels depending on the application and budget:
1. Visual Inspection
The simplest method. Engineers check for physical defects like solder bridges, missing components, or alignment issues.
2. Automated Optical Inspection (AOI)
AOI uses cameras to scan boards for soldering quality, polarity, and presence of components.
3. In-Circuit Testing (ICT)
Tests each component’s electrical characteristics by probing specific test points. It’s fast and accurate for large-volume production.
4. Flying Probe Testing
Uses robotic probes to test low-to-medium volume PCBs without the need for custom fixtures.
5. Functional Testing (FCT)
Verifies the complete assembled PCB in real-world operating conditions. Essential for high-reliability applications.
Testing isn’t optionalâit’s critical. Faulty boards cost time, money, and customer trust.

What Is Robotics PCB Design?
Robotics PCB design refers to the specialized process of creating printed circuit boards tailored for robotic systems. This discipline integrates electronic circuit layout with mechanical constraints unique to robotics, considering factors like dynamic motion tolerance, vibration resistance, and compact spatial requirements. Unlike conventional PCB design, robotics PCB design demands careful coordination between sensor interfaces, motor drivers, and onboard processors while accommodating three-dimensional movement patterns. The design must ensure reliable power distribution across articulated joints and maintain signal integrity despite electromagnetic interference from actuators. Successful implementations balance electrical performance with physical robustness, enabling autonomous navigation, precise manipulation, and real-time data processing within the robot’s operational environment. Modern approaches increasingly incorporate flexible circuits and modular architectures to support adaptive robotic behaviors.

Power Resilienceâ â High-current paths for servo drivers incorporate thick copper pours (â„2oz) and redundant vias to handle sudden torque demands.
Compact Stack-upsâ â Multilayer boards (6-12 layers) achieve high-density routing in confined spaces like robotic joints, using microvias for escape routing.
Vibration Resistanceâ â Components under 10g are secured with corner glue dots or underfill, while connectors use locking mechanisms.
Real-Time Processingâ â FPGAs and MCUs are positioned to minimize latency in control loops, with careful clock distribution to avoid jitter.
Environmental Hardeningâ â Conformal coatings protect against dust/moisture, and thermal vias manage heat in sealed robotic enclosures.
Modularityâ â Board-to-board connectors allow easy expansion, such as adding new gripper modules without redesigning the main controller.
EMI Mitigationâ â Motor driver sections are isolated with moats and shielded with grounded copper fences to prevent interference with sensitive analog circuits.

Metal Core Printed Circuit Boards (MCPCBs) are widely used in high-power applications like LED lighting, automotive systems, and power electronics. They offer superior thermal management compared to standard FR4 PCBs, but several variables impact their final pricing. Whether youâre prototyping or placing a volume order, understanding these factors helps you make informed decisions and avoid unexpected costs.
At Best Technology, we manufacture a wide range of MCPCBs tailored to customer requirements. Below, weâve broken down the main elements that influence pricing so you can better evaluate your design options.
Key Technical Factors That Affect MCPCB Pricing
1. Board Dimensions
Size is the starting point for cost evaluation. For non-rectangular shapes like circles, pricing is based on the longest two sidesâtypically the diameter for round boards. Larger boards require more base material and longer processing time, which increases the unit price.
2. Copper Thickness
Copper thickness directly affects both thermal performance and cost. We offer standard and high-current options, including 0.5 OZ, 1 OZ, 2 OZ, 3 OZ, up to 8 OZ. Thicker copper enhances current-carrying capacity but also raises the complexity and expense of manufacturing.
3. Thermal Conductivity
A higher thermal conductivity helps to dissipate heat more efficiently. For example, 3W/m·K materials offer better heat transfer but are more expensive than standard options. The choice often depends on the power density of your application.
4. Surface Finishing
We support finishes such as HASL_LF (lead-free hot air leveling), OSP (Organic Solderability Preservative), and ENIG (Electroless Nickel Immersion Gold). ENIG is the premium choice due to its excellent solderability and oxidation resistance, though it comes at a higher cost.
5. Board Thickness
The most common MCPCB thickness is 1.6mm ±10%, which meets most design standards. Boards thinner than 1mm or thicker than 2mm will cost more due to non-standard processing. Our maximum capacity reaches 4.0mm ±10% for specific projects.
6. Solder mask Type and Color
Solder mask adds not only a protective layer but also an aesthetic touch. We offer white, black, blue, green, and red options. For high-end applications like LED boards, Taiyo solder mask is preferred for its excellent reflectivity, though it is priced higher than regular options.
7. Stack-Up and Construction
The complexity of the PCB stack-up has a big impact on both cost and manufacturing time. Single-layer boards are simpler and cheaper, while multi-layer, double-sided, or heat sink-integrated boards increase the number of processes, materials, and quality inspections required.
MCPCB Types We Offer
Our company specializes in producing a wide range of MCPCB types to suit various thermal and mechanical requirements:
Single Layer MCPCB
Two Layers MCPCB
Double-Sided MCPCB
Multi-Layer MCPCB
Chip-on-Board (COB) MCPCB
Heat Sink Integrated MCPCB
Each type is customizable to your exact application needsâwhether you’re building high-power LED lighting, automotive electronics, or power conversion devices.
How to Choose the Right Parameters Without Overspending?
When planning your MCPCB project, it’s essential to balance performance requirements with budget constraints. Here are a few suggestions:
Match copper thickness to your current needs â don’t over-specify if lower OZ will suffice.
Select surface finishing based on reliability needs â use ENIG for sensitive components, OSP for more budget-friendly builds.
Ask about solder mask options early â especially for LED projects requiring high reflectivity.
Consider standard thicknesses â unless your application has unique structural or thermal demands.
Let us help with stack-up decisions â especially for complex or multi-functional boards.
