Bob Gilbert, could you pls email me the reliability data for joints made with SN00C and SAC305 alloy. my email: michael_wkk@263.net

We are seeing PLCC socket leads not soldered in our SMT process. We are using a KIC thermal profiling device and we are on 50% greem light process window. All other solder joints on the board looks great. The solder flowed what looks like perfect on

On a small, single stage RPS machine I was going through a dewar (not sure on the capacity differences between what you're using and a dewar) every 6-9 business days running normal 8 hours shifts. Side note, I'd suggest trying out SN100C alloy over

Hello Joseph, Sorry for the bad news but microcracking is a well known potential condition occuring with the SAC305 alloy. Microcracking is a condition being seen with many joints soldered with the SAC305 alloy. It is technically a shrinkage cavity

Rob Just wondering - have you made analysis of your solder alloy on a regular basis? We are using SAC305 but stainless steel parts (e.g. a nut or a washer) dissolve quite quickly.

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

Hello, Could anyone provide some support concern issue with vertical fill of through hole solder. Our lead free wave soldering process is not capable to fill 100% (requirement of our customer)through hole. We made everything (DoE) - different amoun

Thanks, Evtimov. In terms of mechanical drop performance, can we conclude that the higher Ag alloy will have poorer drop shock performance relatively compare to those with lower Ag? The Ag3Sn is a good IMC for welding strength?

Any lead free will eat a leaded designed wave soldering machine. But SN100c will eat it the slowest, our soldering tips used to only last 3 months with SAC305 when we changed to SN100c solder wire we are having around 9 months tip life. Our wave sol
