Guys are complaining the green UV soldermask doesn’t harden well. If it is like the UV glued I’ve tried, it doesn’t adhere very well either. Maybe even CA glue and baking soda could be an option…
Hi Barry, sorry I'm confused - it's a flex circuit, but you don't want
it to flex?
The only other thing that come to mind is encapsulating it in epoxy. use
a release agent and build a mold around your temporary metal plate. once
it's released, flip it and do the same over again.
I'm not sure what your maximum thickness can be here.. or how rigid you
actually need this to be. If it was me though, I'd still be trying the
kapton tape and maybe sandwiching a separate adhesive (like epoxy or CA
glue) between the layers.
This is a tough one.. if you get no better responses here, maybe try the
EEVBLOG forum.. thousands of people there and a lot into repairs.. show
them some pics.
