The finish looks like Immersion Tin or Silver. if its lead free Hot air - could be issue of to high of a Tin Content. find out what brand of Hasl they are using. SL100 Example. Is this tarnished look only being seen after assembly or have you seen

Your problem is at your board house with the finish. There is not enough tin deposited on the ground plane. Could be the current density too low on the ground plane. If electroless they just didn't process these correctly. What is the finish suppose

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.
