Automobile sensor flex boards
Clarification of FPC Types
The solder mask used in our flexible PCBs differs from traditional rigid boards. We utilize a polyimide film that is coated on one side with a semi-cured, non-tacky adhesive-referred to as covercoat in flexible circuits. This covercoat is laminated to encapsulate the copper pattern, leaving solder pads exposed through access holes.
To ensure optimal performance, the covercoat production sheet is cut slightly smaller than the flexible circuit sheet, preventing premature edge sealing and air bubble trapping. Access holes are typically drilled, but for high-volume production, punching offers a more cost-effective solution.
Economic Advantages of Using FPC
For complex circuit designs that require a compact footprint, flexible circuits are typically more economical than traditional connections. They excel in scenarios where rigid circuits are insufficient for size and performance requirements. Our flexible circuits can accommodate intricate designs, including 12mil pads with 5mil through holes and 3mil lines/spacings, maximizing reliability and minimizing potential defects.
