Additional info: I use SAC305 solder paste on Enig PCB.

No, you're correct. Nickel oxidation can be difficult to remove

Hi, does anyone have any experience with common wave soldering defects using SAC305 alloy?.....i am finding a lot of what seem to be shrinkage cracks on the bottom side surface of the soldered components.....there is also a lot of directional cooling

We have tested SN100C for LF wave soldering process since August'05 and currently start production for a month ago. Initially we use SAC305, but due to the shrinkage cavities (micro-crack) we changeover to SN100C. In summary, SN100C did perform well

Switch to SN100C (no pun intended). I cant help with the SAC 305 issues but we should have a wave with SN100 running very soon. I will let you all know how that goes. Please report back on the x-sectioning and share the results. I have heard some v

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

I'm in the high reliability (exempt) sector and have thermal cycled hundreds of boards in the past few years. As far as which is more reliable, SnPb or SAC305, my data is similar to what the technical literature is saying, "It Depends". In low stra

Any issues in your experience using SAC305 for reflow and SN100C for wave on ENIG pcbs? I've seen the CD, but there's not much specific data regarding ENIG pcbs Thanks

250 tons/month) and, as it has been stated here, many customers have switched from SAC305 to SN100C but we are not aware of any customer who has switched from SN100C to SAC305. As the inventor of SN100C states, �once a customer touches the SN100C, he

Hello experts, I have a 50mmx50mm LGA on a PCBA. I Would like to decrease voiding in these joints and I wanted to hear about your techniques to decrease voiding. Stencil is currently 5mil. SAC305. ENIG finish.
