Solder dross has gone from being a cost to be considered by large companies to a very high cost that must be tracked for all who assemble electronic devices.As much as 70% of bar solder can be wasted as solder dross and with SAC 305 now at the $25/Lb

I have never seen excess tin [heard of it, just never seen it]. Excess lead yes, but tin no. See, tin oxidizes faster than lead. This means that dross has a higher tin content than the solder in the pot. So, with a very high dross machine, we regul

The oxide layers are known as wetting inhibitors in component and PCB metallizations. The oxide acts as barrier that prevent the tin diffusion from happening. Besides, in corrosion studies, the role of salt residues -with Cl ion- on some metals is known as being promoters of oxidation or corrosion. On the other hand, most of corrosion studies with tin metallization are focused mainly on the corrosion resistance of tin alloys, but little has been done respecting to the influence of salts on tin metallization wetting. In this paper, a series of experiments was carried over to know the influence of specifically NaCl on BGA wetting given Head in Pillow (HiP) as result.

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.
