howdy yall
almost done with my first ciem
working on the faceplate right now and so my question is:
How can I put the circuit board holding the zobel into the faceplate with fotoplast?
i put the zobel on a small board (will fit, already checked) and would like it to be within the resin of the faceplate.
would i be able to suspend the board in the middle of curing resin or would i have to do this in layers?

Do you want it as aesthetic design?

ill get maybe 1 small bubble once in a while
i use a wax melter

do you know how krystalloid would react?
No. But I never have problems with bubbles, sometimes there is one or two bubbles and if so I simply remove them with a piece of wire.
If you work to quick with fotoplast bubbles are more annoying - but they can be fixed by simply sanding them open and filling up with some more resin. It’s a bit tedious but not a big problem for me.

Got those done today by an audiologist, how far should I trim them? Also do you recommend a more flexible or rigid material for shells? (filoalfa medical flex pla or colorfabb ngen flex for flex or smartfill clear biocompatible petg)
