Pcb|about FPC reinforcement type

FPC It is widely used in electronic products , But because of its low mechanical strength , Easy to crack , Therefore, it is necessary to attach reinforcing materials to strengthen FPC The intensity of . that , You know, fpc What types of reinforcement are there ？ today , Xiaobian will show you something about fpc Three types of reinforcement , For details, please continue to see ：

 

1.PI Reinforcement ： The tolerance can be controlled within +/- 0.03mm, High precision , High temperature resistance （130℃-280℃）.PI Reinforcement thickness ：0.075mm、0.1mm、0.125mm、0.15mm、0.175mm、0.2mm、0.225mm、0.25mm.

2. Steel sheet reinforcement ： Manual assembly is required , The process is more complex , The cost of higher . Steel sheet reinforcement thickness ：0.1mm,0.2mm.

3.FR4 Reinforcement ： If the thickness ＜0.1mm, The tolerance can be controlled within ± 0.05mm. If the thickness ＞1.0mm, Then the tolerance is ±0.1mm.FR4 Reinforcement thickness ：0.1mm、0.2mm、0.3mm、0.4mm、0.5mm、0.6mm、0.7mm、1.6mm.

FPC The advantages and disadvantages of reinforcement are PI The tolerance is small and not very hard ,FR4 The thicker the thinking, the greater the tolerance , The steel sheet is hard and stable, and it is not easy to rework after manual assembly .

The above is about FPC Some knowledge about the type of reinforcement , I hope it helped you .
