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.

What could be possible resons for " Plating Crack on Barrel (tented via)" This tented via is in proximity to parts being hand soldered. The crack in barrel was detected on failure analysis - micro-section of via where barrel is having crack ( circul

I need some information regarding the acceptability/unacceptability of using tented vias with LPI soldermask. Long story on all involved, but basically I have a board that I have had manufactured with no problems which has BGA/uBGA parts, tented via

When tenting vias almost a few vias are not covered completly by Solder Mask. Does this one side open vias affect the Immersion Tin Process ? Do we get chemical residues in the vias ?

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

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 (

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
