Matthew: That you can get solder flow when hand soldering, but not when reflow soldering, seems to be telling you that you're not getting the connection warm enough during reflow. You need to have those connections liquidous + 20*C for at least 5 sec

Questions are: * When you rework these pads, can you get solder to flow on the pads with a soldering iron? * When you profile the board during reflow, what is the temperature on these pads as compared with other similar pads in the vicinity?

Dave Thanks for the input. The thermocouple read 244 on the pad of the socket. We actually found after extensive investigation that it is the coplanarity of the leads. We were shipped a bad batch of sockets form the manufacture. Go figure!!1

What are Resins, Solvents, Activators, and Thickening Agents in Solder Paste and what are their helpful and harmful effects? AND What are the purposes/properties and effects of Sn(Tin), Pb(Lead), Ag(Silver), Bi(Bismuth), In(Indium), Cu(Copper), Ni(

Hi. Anyone in this forum experienced the lead-free solder paste SAC305 and SAC405? What are the differences to expect for solder paste with SAC305 and SAC405? What is the effect of silver (Ag) alloy in solder paste? It was really appreciated if could

Thank you Djo for your sharing. By the way, do you know that which field/product will prefer to use SAC405 paste instead of SAC305 or lower Ag wt% alloy solder paste?

From what I understand SAC305 and SAC405 are considered low silver content and have the better overall mechanical qualities compared to more silver or no silver.

Does anyone have advice about the best low volume (hopefully under $10K) reflow system for SN96 or SAC305 solder? We recently purchased a benchtop IR oven and it is not working well. Jim

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

Hi Davef, thank you for your information.
