How to Design High Speed ADC Evaluation Board?

1. Power Design Considerations

Isolation & Decoupling:

  • Use separate power domains (AVDD, DVDD, CLKVDD) to prevent digital noise coupling.
  • Place multi-stage decoupling capacitors (0.1μF + 10μF + 100μF) near each power pin.

Power Sequencing:

  • Follow the ADC’s specified power-up order (e.g., PVDD before DVDD) to avoid latch-up.

Noise Suppression:

  • Add ferrite beads (e.g., BLM18PG) or inductors on LDO outputs for high-frequency isolation.

2. Clock Design Considerations

  • Low-Jitter Source: Use a dedicated low-jitter clock (e.g., SiT9102) with jitter <10% of ADC aperture jitter.
  • Distribution & Matching: Control differential clock impedance (100Ω ±10%) and match trace lengths (±50mil).
  • Isolation: Keep clock traces away from digital signals and add AC coupling caps (0.1μF) at inputs.

3. Analog Signal Chain Considerations

  • Impedance Matching: Design matching networks (T/π filters or transformers) for ADC input impedance (e.g., 50Ω).
  • Anti-Aliasing Filter (AAF): Set cutoff at 0.4× sampling rate (80% Nyquist) and avoid high-order filters (>4 stages).
  • Protection: Add clamping diodes (e.g., BAT54S) and keep analog traces short (<500mil) to minimize parasitics.

4. Digital Interface Considerations

  • JESD204C/LVDS Optimization: Match differential pairs (100Ω) and add 100Ω termination resistors at receivers.
  • Level Compatibility: Use level shifters (e.g., SN74AVC4T245) if ADC output (LVDS/CMOS) mismatches FPGA.
  • Sync & Reset: Include SYNC~ signals for JESD204C synchronization and debounce reset circuits.

5. PCB Layout & Manufacturing

  • Stackup & Partitioning: Use a 6-layer stackup (Sig-GND-Power-Power-GND-Sig) with analog/digital ground isolation.
  • Critical Routing: Prefer blind/buried vias for high-speed signals and add stitching vias for impedance continuity.
  • Thermal & Reliability: Add via arrays under ADC for heat dissipation and fill via-in-pads with conductive epoxy.

6. EMC & Testing

  • EMC Protection: Use TVS diodes (e.g., SMAJ5.0A) for ESD and ferrite beads for power noise isolation.
  • Test Points: Reserve test pads for power, clock, and analog inputs without probing high-speed lines directly.
  • Temperature Compensation: Select low-drift references (e.g., ADR4525, ±5ppm/°C) and validate performance at extremes.

7. BOM & Supply Chain

  • Component Selection: Prioritize automotive/industrial-grade parts (-40°C to +125°C) and validate alternatives via simulation.
  • Lifecycle Management: Avoid obsolete parts (check Digi-Key) and use common packages (e.g., 0402) for cost efficiency.
  • DFM: Add teardrops to pads and avoid 0201 packages for easier assembly.

    • Clean the workbench: Clear the work area of clutter to create a clean and organized environment for assembly.
    • Wear an antistatic wrist strap: Prevent damage to delicate electronic components from static electricity generated by the human body.
    • Gather tools: Prepare precision screwdrivers, tweezers, a soldering iron (or hot air gun), flux, a desoldering pump, and a multimeter.
    • Check components: Cross-reference the Bill of Materials (BOM) to ensure all required parts for assembly are present and that the tools are suitable for fine electronic work.

    2. Verify Components and Circuit Board

    • Component verification: Check each component’s model, specifications, and quantity against the BOM, including the ADC chip, power module, capacitors, resistors, and connectors.
    • Board inspection: Examine the circuit board surface for scratches, shorts, or open circuits.
    • Position alignment: Confirm that each component matches the corresponding pads on the board for accurate installation.

    3. Solder Surface-Mount Components

    Wear an antistatic wrist strap and solder components from smallest to largest:

    • Solder small 0402/0603 resistors and capacitors using drag or spot soldering, avoiding bridges.
    • For BGA-packaged ADC chips, apply flux to pads and heat using a hot air gun or reflow oven following the temperature profile to prevent localized overheating.
    • When soldering QFN/LGA components, align pins carefully and use tweezers for support during soldering.

    4. Install Through-Hole Components
    For components like power connectors, headers, and switches, manual soldering is sufficient:

    • Insert component leads into corresponding holes, heat pads from the back of the board, and remove the soldering iron promptly once the solder melts to keep leads upright.
    • Trim excess leads to less than 1.5mm to prevent short circuits.

    5. Connect External Modules and Interfaces

    Install sub-boards or expansion modules (e.g., clock modules, signal conditioning circuits) as per design requirements:

    • Secure modules with headers or connectors to ensure good contact.
    • Control solder volume when soldering RF coaxial interfaces or high-speed differential lines to avoid signal distortion.

    6. Preliminary Inspection and Cleaning

    • Use a multimeter to test power lines, ground lines, and key signal lines for continuity, shorts, or opens.
    • Clean flux residue and solder splatter from the board using alcohol and an antistatic brush to prevent long-term corrosion and poor contact.

    7. Functional Testing and Debugging

    • Connect power and an oscilloscope, power up gradually, and monitor voltage stability.
    • Input test signals (e.g., sine waves, square waves) and use a logic analyzer or PC software to verify ADC sampling accuracy, signal-to-noise ratio (SNR), and other parameters against specifications.
    • Adjust component parameters (e.g., matching resistors, decoupling capacitors) or optimize layout based on test results until performance meets requirements.

      What Is High Frequency Inverter Board?

      A high-frequency inverter board is a power electronic device that converts direct current (DC) into alternating current (AC). Its core feature is the use of high-frequency switching technology (typically above 20kHz), which rapidly switches power devices (such as MOSFETs and IGBTs) on and off to achieve power conversion. Compared to traditional low-frequency inverters (50/60Hz), high-frequency inverter boards significantly reduce device size and improve efficiency by utilizing high-frequency transformers and pulse-width modulation (PWM) technology.

      What Is High Frequency Inverter Board?

      How Does a High Frequency Inverter PCB Board Work?

      • DC input: DC power from batteries or solar panels enters the inverter board.
      • High-frequency inversion: Power devices (such as IGBTs) switch rapidly under the control of high-frequency PWM signals, converting DC power into high-frequency AC pulses (typically 20kHz-1MHz).
      • High-frequency transformation: High-frequency AC power is converted (stepped up or down) by a small high-frequency transformer.
      • Rectification and filtering: The high-frequency AC power output from the transformer is converted to DC power by a rectifier bridge, and then smoothed to a stable DC voltage by a filter circuit.
      • Power frequency inversion: The filtered DC power is converted to 50/60Hz AC power by an inverter circuit (such as a full-bridge or half-bridge configuration) and output to the load.
      • Feedback control: A sampling circuit monitors the output voltage and current in real time and adjusts the PWM duty cycle to maintain a stable output.
      How Does a High Frequency Inverter PCB Board Work?

      What Does a High Frequency Inverter Board Do?

      Functions of high frequency inverter PCB board:

      • DC-AC Conversion: Converts DC power from batteries, solar panels, or other sources into 220V/50Hz or 110V/60Hz AC power for use in industrial equipment.
      • Voltage/Frequency Regulation: Utilizing PWM control technology, the output voltage and frequency are adjustable to meet varying load requirements.
      • Waveform Optimization: Utilizes sinusoidal or modified sine wave output to reduce harmonic interference and improve power quality.

      What Are Circuit Diagram Called?

      A circuit diagram is a technical drawing that uses standard symbols (such as resistor) to graphically represent electronic components and their connections. It is mainly used to design, analyze, and understand the structure and working principles of circuits.

      What Are Circuit Diagram Called?

      What Are the Symbols Used in Circuit Diagrams?

      Symbols are used in circuit diagrams:

      • Power Sources: Battery (short and long parallel lines), AC Supply (sine wave), Ground (horizontal line with vertical lines/triangle).
      • Resistors: Fixed (zigzag line or rectangle), Variable (zigzag with arrow).
      • Capacitors: Fixed (two parallel lines), Variable (parallel lines with arrow), Electrolytic (+/- polarity marked).
      • Inductors: Coil (multiple spirals or waves).
      • Diodes: Standard (triangle with bar), LED (diode symbol with light rays).
      • Transistors: Bipolar (e.g., NPN/PNP lines with arrow), MOSFET (three lines with symbols).
      • Switches: SPST (break in line with hinge point), Pushbutton (spring mechanism implied).
      • Wires & Connections: Solid Line (wire), Dot (connection), Dashed Line (non-physical/logical connection).
      • Transformers: Overlapping coil symbols.
      • Integrated Circuits (ICs): Rectangle with labeled pins (e.g., op-amp as triangle).
      • Sensors & Outputs: Microphone (wave in circle), Lamp (circle with ‘X’), Speaker (cone symbol).

      What Are the Two Types of Circuit Diagrams?

      1. Schematic Diagram:

      • Primary Purpose: Shows the functional logic and electrical connections between components within a circuit.
      • Characteristics: Uses standardized symbols (like resistors, capacitors, transistors) to represent components. Ignores their physical size, shape, or actual placement location. Lines represent electrical connection paths, not physical wires.
      • Uses: Designing, analyzing, understanding circuit operation, calculating currents/voltages, and theoretical troubleshooting.

      2. Wiring Diagram / Layout Diagram:

      • Primary Purpose: Shows the actual physical placement, arrangement, and connection relationships of components and wires.
      • Characteristics: Component representations may be closer to their physical appearance or simplified outlines. Includes information on physical dimensions, terminal locations, cable routes, and connection point identifiers. Focuses on physical implementation details.
      • Uses: Equipment assembly, wiring installation, field repair, and maintenance.
      What Are the Two Types of Circuit Diagrams?

      What Are the Four Rules for Drawing Circuit Diagrams?

      1. Use Standardized Symbols

      • All components in circuit diagrams (e.g., resistors, capacitors, diodes, transistors) must be represented using internationally or industry-recognized standardized symbols. Avoid arbitrary or non-standard drawings to ensure readability and universal compatibility.

      2. Ensure Clear and Logical Layout

      • Components should be arranged according to signal flow (from input to output) or functional modules to minimize crossing lines. Separate main circuits (e.g., power supply, load) from control circuits (e.g., switches, sensors) into distinct sections. Clearly label critical connection points.

      3. Follow Wiring Conventions

      • Use straight lines for conductors, with right-angle bends (not rounded). For crossed but unconnected wires, use a “jump” symbol (e.g., a semicircular arc) to avoid confusion. Mark connection points with solid dots to eliminate ambiguity.

      4. Provide Complete and Precise Annotations

      • Label all components with their parameters (e.g., resistance values, capacitance values, part numbers) and identifiers (e.g., R1, C2). Specify power supply voltage polarities and magnitudes. Add explanatory notes for key nodes to ensure the diagram is self-contained and requires no additional clarification.

      How to Make an Easy Circuit Diagram?

      1. Define the Purpose of the Circuit

      • Determine the circuit’s function (e.g., lighting an LED, powering a motor) to guide component selection.

      2. List All Required Components

      • Power source: Battery, power supply, or USB port.
      • Load: The component that uses power (e.g., LED, resistor, motor, buzzer).
      • Connectors: Wires, jumper cables, or breadboard connections.
      • Control elements: Switches, buttons, or relays (optional but useful for interaction).

      3. Choose a Drawing Tool & Software

      • Fritzing: Free, beginner-friendly, with drag-and-drop components.
      • Circuit.io: Online tool with simulation capabilities.
      • Microsoft Visio/Lucidchart: General-purpose diagramming tools (use electrical symbols libraries).
      • Hand-drawn: Use graph paper, a ruler, and standardized symbols (see Step 4).

      4. Draw the Power Source

      • Placement: Position the battery or power supply at the top or left of the diagram (conventional layout).
      • Symbol: Use the standard battery symbol (two parallel lines of different lengths, long = positive, short = negative).
      • Label: Include voltage (e.g., “9V”) and polarity (+/-).

      5. Add the Load Component

      Placement:

      • Place the load (e.g., LED, resistor) to the right or below the power source.

      Symbols:

      • Resistor: Zigzag line (e.g., “R1”).
      • LED: Triangle with a bar at one end (pointing toward negative).
      • Motor: Circle with the letter “M” inside.
      • Label: Assign a reference designator (e.g., “D1” for LED, “R1” for resistor) and value (e.g., “220Ω”).

      6. Connect Components with Wires

      • Use straight lines to represent wires.
      • Avoid crossing lines; if unavoidable, use a dot to indicate a connection or a jump (semicircle) to show no connection.
      • Keep lines horizontal or vertical for a clean look.

      7. Include Control Elements (Optional)

      • Purpose: Switches or buttons let you turn the circuit on/off without disconnecting wires.
      • Placement: Insert the switch between the power source and load.
      • Symbol: Use the SPST switch symbol (a line with a break and a pivot).

      8. Label All Components Clearly

      • Component type (e.g., “LED,” “Resistor”).
      • Reference designator (e.g., “R1,” “D1”).
      • Value/rating (e.g., “220Ω,” “9V”).

      9. Review and Simplify

      • Remove unnecessary components or wires.
      • Use color-coding (e.g., red for power, black for ground) for clarity.

      10. Save or Export the Diagram

      • Save as a PDF, PNG, or editable file (e.g., .fzz for Fritzing).
      • Share or print for reference.

      • Use jumpers: Mark non-connected crossings with a small semicircle (most software has a “bridge” tool).
      • Layer your layout: Place high-frequency signals on top layers and low-frequency lines on bottom layers (for multi-layer PCB designs).
      • Re-route wires: Rotate components or adjust positions to minimize crossings (e.g., rotate a resistor by 90°).

      Q3: What if my circuit simulation results don’t match expectations?

      A3: Below are solutions:

      Check connections step-by-step:

      • Ensure all components are properly connected (no floating pins).
      • Verify power supply polarity (e.g., LED anode/cathode orientation).

      Validate parameters:

      • Confirm resistor/capacitor values match calculations (e.g., use Ohm’s Law for LED current-limiting resistors).

      Test submodules separately:

      • Debug the oscillator circuit first, then the output stage.
      • Tool recommendation: Use Tinkercad Circuits’ “Probe” feature to monitor voltage/current at each node in real time.

      Q4: How do I add clear annotations to complex circuit diagrams?

      A4: Below are solutions:

      Label components:

      • Assign unique IDs (e.g., R1, C2, U1) and group them by function (e.g., R1–R3 for power section).
      • Write parameter values next to components (e.g., “10kΩ ±5%”).

      Annotate nodes:

      • Name critical signal points (e.g., “Vin_ADC,” “PWM_Out”).
      • Add arrows and text for complex connections (e.g., “→ This line feeds the motor driver”).

      Include a legend:

      • Add a “Symbol-Function Key” in the corner (e.g., “□ = Relay, △ = Op-Amp”).
      • Example: In an op-amp circuit, label: “R1/R2 form a feedback network. Gain = 1 + R2/R1.”

      Q5: How can I improve the neatness of my hand-drawn circuit diagrams?

      A5: Below are solutions:

      • Use graph paper: Draw components to scale (e.g., a resistor spans 2 squares in length, 1 in width).
      • Leverage templates: Print standard component outlines (e.g., LEDs, switches), trace them onto your paper.
      • Draw in sections: Sketch the power supply first, then control circuits, and combine them later.

      Heavy copper PCB design & Thick copper PCB Prototype​
      Friday, September 5th, 2025

      Heavy copper PCB design refers to creating printed circuit boards with much thicker copper layers than standard boards. While a typical PCB uses 1 oz copper (about 35µm), heavy copper PCBs range from 2 oz to 20 oz per square foot, sometimes even higher for extreme power needs.

      Thick copper layers improve current handling, enhance mechanical strength, and allow for compact, high-power layouts without compromising reliability.

      Heavy copper PCB design & Thick copper PCB Prototype​

      What is heavy copper PCB?

      Heavy copper PCB uses copper conductors that are much thicker than standard PCBs. While standard boards use 1 oz copper (about 35µm), heavy copper boards range from 2 oz to 20 oz per square foot. Some extreme designs even go beyond that, which we call extreme copper PCB.

      So, why so thick? Because thicker copper carries more current without overheating. It also improves mechanical strength, making the board more robust for harsh environments.

      In short, heavy copper PCBs are not ordinary. They are designed for power electronics, automotive, defense, and industrial equipment that demand strength and stability.

      Why use thick copper PCB?

      Power systems produce heat. A lot of it. If your PCB cannot handle high current, failure is just a matter of time. That’s why thick copper PCBs are vital.

      Here’s why industries love them:

      • Superior current capacity: Thick copper allows higher amperage without damaging traces.
      • Better heat dissipation: No more overheating issues in power circuits.
      • Strong mechanical bonding: Ideal for connectors, heavy components, and thermal sinks.
      • Design flexibility: Perfect for high-density interconnects and power distribution layers.
      Heavy copper PCB design & Thick copper PCB Prototype​

      When reliability is non-negotiable, heavy copper PCB design is the answer.

      How thick is copper in a heavy copper PCB?

      Thickness matters. A standard PCB has 1 oz copper (35µm). For heavy copper PCBs, the thickness ranges from:

      • 2 oz (70µm): Entry-level heavy copper
      • 3 oz to 6 oz (105µm to 210µm): Common for power electronics
      • 8 oz to 20 oz (280µm to 700µm): Extreme copper PCB for very high power

      The choice depends on current requirements, thermal performance, and mechanical strength. If your design demands high current flow, you need more copper.

      What are the common problems in heavy copper PCB design?

      Designing a heavy copper PCB is not as simple as adding more copper. It brings challenges:

      • Etching Issues: Thick copper needs deeper etching, which requires advanced technology.
      • Uneven Trace Widths: Incorrect design may lead to imbalance.
      • Plating Difficulties: High copper density affects via plating and reliability.
      • High Cost: More copper equals higher material and manufacturing cost.

      With a professional heavy copper PCB manufacturer like BEST Technology, these challenges are easily solved. Our team uses controlled etching and advanced plating to ensure accuracy and quality.

      How much does heavy copper price affect cost?

      The price of heavy copper PCBs depends on:

      • Copper weight (2 oz, 4 oz, 6 oz, etc.)
      • Board size and layer count
      • Design complexity
      • Quantity
      Heavy copper PCB design & Thick copper PCB Prototype​

      Copper is not cheap. A 6 oz PCB will cost more than a 2 oz PCB due to more copper and processing time. If you want exact pricing, contact us at sales@bestpcbs.com. Our experts will provide a detailed quotation and free consultation.

      Applications of Copper Tape PCB Repair

      How to Use Copper Tape for PCB Repair?

      Below are steps of copper tape for PCB repair:

      1. Inspect and Clean the Damaged Area

      • Visually locate the broken trace. Use a magnifier to confirm the damage range.
      • Clean the area with an alcohol-soaked cotton swab to remove residue, oxidation, or solder mask. If the solder mask covers the break, scrape it off with a blade or sandpaper to expose the copper base.

      2. Cut the Copper Tape

      • Trim the tape to match the broken trace’s shape, ensuring it’s slightly larger than the damaged zone (covering intact copper on both ends).
      • The tape width should match the original trace. Length must span the break and overlap adjacent copper (at least 1-2mm).

      3. Apply the Copper Tape

      • Press the tape flat onto the break, ensuring full contact with exposed copper and no air bubbles.
      • The tape must fully cover the break and extend to nearby pads or vias for reliability.

      4. Solder to Secure

      • Quickly solder the tape’s ends to the PCB copper. Avoid overheating (back adhesive may melt).
      • Use low-temperature solder. Keep the iron’s contact time under 2 seconds to prevent tape detachment.
      • If repairing a pad, solder the component lead to the tape simultaneously.

      5. Trim Excess Tape

      • Carefully cut or scrape the tape edges to match the original trace width.
      • Warning: The repair is fragile—avoid excessive force to prevent lifting.

      6. Reinforce and Insulate

      • (Optional) Cover the tape with insulating tape (e.g., Kapton) or apply solder mask to prevent shorts or damage.
      • For high-stress areas (e.g., PCB edges), reinforce with epoxy (e.g., Araldite).

      7. Test Functionality

      • Use a multimeter to check continuity (resistance should be near 0Ω).
      • Power on the device and monitor for poor contact or overheating.

            Common Copper Busbar Material Grade & Properties

            How to Choose Copper Busbar Material?

            Below are selection guide to copper busbar material:

            1. Material Type and Conductivity

            High-purity copper as the foundation:

            • Electrolytic Tough Pitch (ETP) copper (purity ≥99.9%) is the industry standard, offering ≥98% IACS conductivity for minimal energy loss.
            • Oxygen-Free Electronic (OFE) copper (purity ≥99.99%) is ideal for high-frequency applications (e.g., RF systems) due to its ultra-low oxygen content (<0.0005%), preventing oxide formation at joints.

            Alloy avoidance:

            • Unless mechanical strength is critical (e.g., seismic zones), skip brass or copper alloys, as even 0.5% alloy addition can reduce conductivity by 5–10%.

            2. Surface Treatment and Corrosion Resistance

            Plating strategies:

            • Silver plating (2–5µm): Best for low-resistance contacts in high-current switches (e.g., circuit breakers), but requires laminating films to prevent scratching during installation.
            • Tin plating (5–10µm): Cost-effective for general-purpose use, offering sacrificial protection against oxidation. Avoid in acidic environments (pH <6).
            • Nickel plating (3–15µm): Resists sulfur-rich atmospheres (e.g., chemical plants) but increases contact resistance by 10–15%.

            Edge finishing:

            • Deburr all edges with a 1.5mm radius minimum; use CNC machining for precision. Chamfer angles >45° reduce electric field concentration.

            3. Sizing and Current-Carrying Capacity

            Cross-sectional design:

            • Calculate using the formula: A = I × √(t) / (K × ΔT)
              (Where A = area (mm²), I = current (A), t = time (s), K = material constant (0.049 for copper), ΔT = temp rise (°C)).
            • Example: For 1000A over 1s with ΔT=30°C, A ≈ 1000 × 1 / (0.049 × 30) ≈ 680mm² (use 700mm² for safety).

            Shape optimization:

            • Flat bars: Best for natural convection cooling (e.g., busbar trunks).
            • Hollow tubes: Reduce weight by 40% while maintaining 85% conductivity (ideal for aerospace).

            4. Fabrication and Installation

            Precision processing:

            • Use laser cutting for holes <3mm to avoid deformation. For bending, maintain a bend radius ≥2× thickness to prevent cracking.
            • Clean surfaces with isopropyl alcohol after machining to remove oil residues.

            Connection best practices:

            • Copper-to-copper: Use friction welding for permanent joints (shear strength >200MPa).
            • Copper-to-aluminum: Apply zinc-based dielectric coating (e.g., Dow 17) before bolting to mitigate galvanic corrosion.

            Insulation requirements:

            • Use silicone rubber (Class H, 180°C) for high-temp zones. For outdoor use, add UV-resistant coating.

            5. System Compatibility and Standards

            Standard alignment:

            • IEC 60439-1: Mandates busbar temperature rise ≤70°C under full load.
            • UL 758: Requires flammability rating V-0 for insulation materials.

            Future-proofing:

            • Pre-drill M6/M8 holes with 10mm spacing for future branch connections.
            • Use modular busbar systems (e.g., plug-in units) for easy capacity upgrades.

            6. Quality Assurance & Brand Trust

            Inspection checklist:

            • Visual: No discoloration (blue/green patches indicate oxidation).
            • Dimensional: Use calipers to verify tolerance (±0.1mm for critical dimensions).
            • Electrical: Conduct 4-wire resistance tests (≤0.00001Ω accuracy).

            Certifications:

            • Demand ISO 9001 (quality management) and IEC 62560 (safety for low-voltage systems).

            7. Cost Optimization and Alternatives

            Copper vs. aluminum:

            • Aluminum costs 30% less but requires 1.6× larger area. Use only in dry, low-vibration environments (e.g., solar farms).

            Sustainable options:

            • Recycled copper (95% purity) reduces carbon footprint by 65% but requires rigorous testing for impurities (e.g., lead <0.001%).

                        What Is Copper Busbar Ampacity?

                        Copper Busbar Ampacity refers to the maximum continuous current a copper busbar can safely carry under specific environmental conditions (e.g., temperature, heat dissipation, insulation level). It is determined by factors like cross-sectional area, copper purity, surface treatment, and installation methods (such as dense packing or ventilation).

                        How to Calculate Copper Busbar Ampacity?

                        Methods about how to calculate copper busbar ampacity:

                        1. Cross-Sectional Area Estimation (Single Busbar)

                        • W: Busbar width (mm)
                        • K: Thickness factor (e.g., 18 for 10mm thickness)

                        2. Multi-Layer Busbar Correction

                        • Double-Layer: Idouble​=Isingle​×1.58
                        • Triple-Layer: Itriple​=Isingle​×2

                        3. Temperature Correction

                        • Lower Temperature (e.g., 25℃): Icorrected​=I40​×1.18
                        • Higher Temperature (e.g., >40℃):Icorrected​=I40​×0.9

                        4. Simplified Formula

                        • Formula: I=W×(T+8.5)
