- Resistive Heating Element Design: The heating element can be designed using traces of a conductive material (like copper) on the PCB. The resistance of these traces, and hence the temperature reached, will depend on the copper thickness, trace width, and overall design.
3. Calculate Resistance Required- $ \rho $ is the resistivity of copper ($1.68 \times 10^{-8} \Omega \cdot m $),
- $ L $ is the length of the trace (m),
- $ A $ is the cross-sectional area of the trace (m$^2$) which can be calculated as $ \text{thickness} \times \text{width} $.
5. Design on Flux.ai- Step 1: Lay out a grid in the dimensions of 200mm x 200mm to define your workspace.
- Step 2: Design the trace pattern. A meandering pattern is effective for maximizing the length of the trace within a limited area, improving the heat distribution.
- Step 3: Ensure that the trace width and thickness provide the resistance calculated in the earlier steps.
6. Additional Considerations- Thermal Management: Include a temperature sensor in your design to monitor the PCB temperature to ensure it doesn't exceed 80°C.
- Power Connection: Designate points for the power supply connection to the heating trace. This could be a simple two-pin connector, considering the voltage and current requirements.
- Flexibility Considerations: Ensure traces are designed in a way to maintain flexibility, avoiding areas of high stress that could lead to failure.
