| During inspection and test we find leads which do not get soldered. Some are because of insufficient paste, but with others everything looks right. This will only happen on 1 to 2 pins, and it is not isolated to a specific type of ic or location o

First, how oxidized are these solder balls? Will the take solder using your routine flux / paste? Second, on restoring solderability, the three basic methods you can use to restore solderability on components are: * Highly active fluxes in a retinn

Effect of Surface Oxide on the Melting Behavior of Lead-Free Solder Nanowires and Nanorods

Technical Library | 2013-07-18 12:12:40.0

Lead-free nanosolders have shown promise in nanowire and nanoelectronics assembly. Among various important parameters, melting is the most fundamental property affecting the assembly process. Here we report that the melting behavior of tin and tin/silver nanowires and nanorods can be significantly affected by the surface oxide of nanosolders.
