Will there be any issue if soder paste of SnPbAg is used for airborne application (PCB)

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?

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?

What do you mean by "airborne"? We have been using SnPbAg for 15+ years to build assemblies to IPC class II standards although with most assemblies going to Pb free, we are not using it near as much as we used to.

Hi, can't find answer to my question on web - maybe someone can help would it be compatible to use a wire of Sn62Pb36Ag2 for a product made with Sn63Pb37 paste ??? regards

Whether or not SnPbAg will cause issues is trivial. You must build to the solder specified on the print.

I think, it will be no problems, if there's no Bi in a covering of components.

Let me thank you for the reply. We are manufacturing products which are fitted on the aircraft. We are using SN63Pb37 solder paste for PCB assembly. Of late one of the solder paste supplier recommended SnPbAg for better solder-ability & reliabi

nope, but why such a high reflow temp for lead paste?
