measuring inprocess copper plating thickness

2017/3/1 4:27:54

Hi Folks,

I am looking for some info. and possibly a source on measuring inprocess copper plating thickness for Flex PCB manufacturing facilities.

I have tried XRF, E-Current method but the supplier told us that it wont work with Flex material - thickness is also an issue for this matter.

I am looking for non-destructive inexpensive testing method beside hole gauging.

Thanks in advance.
