Thanks Gaurav I am a University student in the UK and am doing some research on nozzle design for the University. I am trying to get a gerneral picture of how long these nozzles last and there mode of failure. I beleive the nozzles are RSS, MA and

1)Though in many cases the difference between SAC305 and SAC405 was small,and not always statistically significant, it was observed that SAC405 generally outperformed SAC305 joints. Under 0°C to 100°C thermal cycling,no statistically significant

| We had some failures on an IC package that the manufacturer has put down to moisture inside the package, leading to popcorning. | This seems a bit odd, the package is a PLCC 84 which is quite thick. I have only seen this problem on thin packages. |

| We are experiencing 'lifting' on one or more sides of a QFP. Poor lead co-planarity has been ruled out by independent tests. Please tell me which of the two remaining failure modes is the most probrable? | | 1. Expansion of gases in vias underneat

Grant I'm gonna have to go ahead and sort of disagree with you there. The studies that I've been reading from various BGA Manufacturers have identified insufficient homogenizing / coalescing of the Sn/Pb Paste with the SnAgCu balls. Ball not touchi
