Using flexible FR4 boards for PCB

[LaceSensor]

Hi

I got some black PCB material for making some faceplates with, its quite flexy.
Is this ok to make PCB with aswell?

Seems obvious that the answer is YES because it is by nature PCB material, just seems a tad flexy, especially for bigger boards.

Any experience?

Its about 0.8mm thick

It depends on the size of the board. For small PCBs, it should be fine. But, as the size increases (and the weight of the components) it may start to flex more than you want. Once, I did a sizable PCB on some real thin material and it ended up flexing and retaining that shape. This was probably because I had it in a vise when soldering and as the PCB heated up it warped.

I think .8mm is still pretty sizable so it may not be an issue at all.
