Yes, a polite complaint to our board shop later and the next batch didn't have that problem at least. I'm not convinced it's an ENIG issue as there was variability panel to panel in the first place.

Hi, From a Manufactures choice - Green is the best due to it is the most commonly used mask color in the industry & cheapest. Kind a like Red paint for Barns. For US shops, most only have one LPI machine and to continually switch from Green to othe

Concern about the failure of lead-free BGA packages when portable devices such as cell phones are accidentally dropped and a general concern about the resistance of these packages under shock loading has prompted an interest in the impact strength of the soldered BGA connection. This paper reports the results of the measurement of the impact strength of lead-free 0.5±0.01mm diameter BGA spheres on 0.42mm solder mask defined pads on copper/OSP and ENIG substrates using recently developed equipment that can load individual BGA spheres at high strain rates in shear and tension.

Nickel corrosion in ENIG and ENEPIG is occasionally reported; when encountered at assembly it manifests as soldering failures in ENIG and wire bond lifts in ENEPIG. Although not common, it can be highly disruptive, resulting in missed deliver schedules, supply chain disruption, failure analysis investigations, and liability - all very costly.
