As your know, Flexible circuits(FPC) provide major benefits over rigid circuit boards, but they also have the shortcomings. Please see below shortcomings of FPC Characteristics:

1. Small mechanical strength,easy to crack;
2. Difficulties in process design;
3. The possibility of re-processing is low;
4. The difficulties for checking;
5. Can’t Carrying heavy parts for single one;
6. Easy to break, beat, wound;
7. Higher cost of the product.

Althrough FPC have these shortcomings, but now more and more widespread use of Flex circuits, more and more advanced technology. We can develop the strong points and avoid the weak points and provide quality goods at competitive cost.
