Flexible electronics , also known as flex circuits , is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates , such as polyimide , PEEK or transparent conductive polyester film.Additionally, flex circuits can be screen printed silver circuits on polyester .There are many kinds of flexible circuit board thickness, according to the specific production needs to choose a different circuit board.

Flexible Circuit


1. Coverlayer of flexible circuits:

1). 12.5um: PI:12.5um; adhesive:15um; total thickness: 27.5um
     PI:12.5um; adhesive:25um; total thickness: 37.5um
2). 25um:   PI: 25um;  adhesive:25um; total thickness: 50um

2. Substrate thickness of flex circuits

1).Single RA copper:

18/12.5UM: copper thickness:18um; PI:12.5um;adhesive:13um; total thickness 43.5um
35/25UM:  copper thickness:35um; PI:25um; adhesive: 20um; total thickness 80um

2).Double-sided RA copper:

18/12.5UM: copper thickness:18um; PI:12.5um; adhesive: 13um; total thickness: 74.5um
35/25UM: copper thickness:35um; PI:25um; adhesive: 20um; total thickness: 135um

The above is the type of flexible circuit boards, I believe you have learned part of the knowledge, if you want to know more, you can click the link.
