Hi, Thanks for this reply. Our problem is that our customer complained that the pcb that we sent them is not Immersion silver though the actual appearance of the pad is silver. They claim that it is only silver and not Immersion silver. We asked our

I have seen this affect on Immersion Tin and OSP. 70 to 90 % of the solder wicks to the lead and forms a "single" homogenous solder mass. This even though the pad was 100 % covered with paste... Evaluated different solder paste...did find variatio

1. Which manufacturers have proven the immersion silver is reliable after solder joint assembly? 2. Who has published guidelines for storing and handling immersion silver boards? 3. Is the immersion silver finish wire bondable? epoxy bondable? or j

All, We know that incomplete immersion silver could potentially lead this creeping corrosion. Is there any way to check bare PCB for incomplete immersion silver coverage, especially on the via hole area? Thanks, Sean.

I have used both immersion silver and immersion gold and found that the immersion silver performed better in reliability studies for BGA's using 63/37 paste.

Hi Again, In answer to DaveF - Yes solder is fine where the solder paste is deposited , but the part of the pad visible after pasting is still visible after reflow. Previously the solder paste & all the gold diffused & flowed giving a complete silve
