KRIKIES! tenting WILL inhibit solder flow through the top-side me lad. In the meantime, me chap, have you tried to adjust wave parameters? i've read threads here that a vibrating wave will tend to push solder up through holes.

Q1. What are you guys doing for filled/tented/plugged vias on the BGA site? A2. 2221A, 4.5.1 tells you the vias have to be tented on both sides. Q2. What type of issues can this cause if using no filled/tented/plugged vias on the BGA site? A2. BGA

Yes, some solder masks do not tent well, because the material is too thin. That�s the trade-off. Thin masks: * Conform well to [don't bleed onto] fine pitch features. * Tent vias poorly, requiring an additional "plugging" step. As you imply, if th

Tented vias on ENIG boards

We have been using ENIG for 8 years as our primary board finish. We have not seen any issues with tenting the vias. We have used a number of suppliers. The ENIG from China does not seem to solder quite as well in general but only had black pad from o
