2.Board Thickness(1.2/1.6/1.0/0.8mm)
3.Oil Ink Color(Green,Red,White,Black,Blue)
4.Surface Treatment Process(OSP,HASL,ENIG,Lead,Lead Free)
5.Solder mask requirements
6.Silkscreen requirements ect,.
Key Manufacturing Technical Challenges of Automotive PCBs
1.Extreme Environment Adaptability:Specialized substrates (high-TG FR-4, MCPCB) require optimized lamination to maintain structural and electrical stability across -40°C to 125°C, resist continuous vibration, and endure high humidity without performance loss.
2. High-Precision Trace Processing:High-resolution photolithography is needed to create ultra-fine lines/spaces (≤0.1mm) for HDI boards, with strict copper thickness control to minimize signal loss and crosstalk for ADAS and autonomous driving systems.
3. EMI/EMC Shielding Integration:Shielding layers (conductive coating, metal cladding) must be integrated into the board structure during fabrication, ensuring consistent coverage to suppress electromagnetic interference for safety-critical circuits.
4. Reliable Interlayer Connection:Blind/buried vias for multi-layer EV power PCBs demand high-precision drilling and electroplating to ensure uniform copper coverage on via walls, preventing conductivity failures from plating voids or insufficient thickness.
5. Automotive-Grade Compliance Control:Full adherence to IATF 16949 standards is mandatory, including 100% AOI for zero-defect soldering and batch thermal stability testing to verify long-term reliability for automotive use cases.
6. Flex-Rigid Hybrid Structure Fabrication:Compatible adhesives and optimized lamination parameters are required to balance bonding strength between rigid and flexible sections, preventing delamination under repeated bending for curved vehicle components.
