When I use my etchable coil part in a project and export the gerbers then it turns out that the entire coil has a solder mask. But only the solderpads should have it.
So how can I turn the solder mask off over the coil itself?
I can find several posts in the old forum on solder mask, basically it also people asking more control over the solder mask, but I can’t find a clear answer how to do this. (If possible at all)
What options are available?
BTW. ENIG production (Gold Plated) is not an option. Allthough it may look very nice.
