Electronics Forum | Fri Dec 01 13:55:44 EST 2017 | emeto

Brikainis, it looks like these vias are not plated and closed. I would say that thickness of your paste is lifting the part. Are you willing to try another stencil with ground pad apertures matching the via holes? It is probably worth trying. Anothe

If you buy old equipment like these I would recommend buying from one of the companies that advertise here. Make sure it's one that has staff to support you. Some will say they have staff but they actually use contractors. That's not always bad bu

I figured it was just going to take a little searching to find a (more expensive) stamp that used an (more expensive) indelible ink. Not the case. Just can't find anything at all, and the stamp manufacturers say not to use any ink but what they provi
