Is there a reason you use etch-resist film instead of an solder mask
proper? I had been considering getting set up for solder mask as well
Dynamask film is harder to get and significantly more expensive.
Unfortunately nobody in China, and I mean NOBODY in China, seems to sell Dynamask (or any similar dry film soldermask), while dry film resist is everywhere.
I suppose it's simply down to the PCB fabs not using dry film for solder mask, so there's no "surplus" like there is with resist.
