http://www.saturnelectronics.com/docs/Getting_the_Lead_Out.pdf This is a document provided by one of our suppliers discussing lead free PCB considerations. Within the document, it mentions black pad being associated with tented vias. Thanks John S.

if you are not using them for test points or want them filled with solder for current carrying capability then tent them puppies. i was able to move our company away from exposed vias many years ago and this eliminated lots of hairline shorts between

I asume you're not ICT-ing this board and using the vias for test points?

Tented vias have solved problems for me in the past, but never created any. I have heard seemingly pointless discussions about whether or not the EE that designed the board designed it with filled vias in mind (a consideration of current carrying c

Guideline for Tenting Interstitial BGA Vias It is difficult to give a complete recommendation on via tenting without an idea what process conditions are required (ex: wave pass, double reflow, rework etc.). Via Pads (as Test Points) - On Bottom

Sorry. I actually should clarify those slides. Black pad is not associated with tented vias. Also, you can tent vias with soldermask, but this requires the immersion gold process to be completed prior to soldermask. As such, all copper features (

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.

Dreamsniper What is the rationale for the double plugging? And why from both sides?
