PCB Materials & Stackups
- 1. What is the thermal conductivity of aluminum core PCBs?
- 2. What is the layer stackup for a standard 4-layer FR4 1.6mm PCB?
- 3. What are the stackup options and loss tangent for thin PCBs (0.4–1.0mm)?
- 4. Can missing data in impedance-controlled stackup entries be corrected?
- 5. What high-frequency PCB materials do you support (Rogers, PTFE)?
- 6. What copper weight options are available for PCB, and how does it affect trace width?
- 7. What Tg options are available for FR4 PCBs (Tg135-140, Tg170)?
- 8. What PCB materials do you offer (FR4, aluminum, Rogers, flex)?
