Is this the same as LF HASL using Nihon Superior SN100c alloy

Howard,
Can you provide or direct me to documentation regarding the nickel and germanium depletion associated with SN100C? This is the first I have heard of it.
Thanks
R. Dean Stadem

Good Morning Technetters.
It is believed by our industry that SN100C suffers from nickel depletion (which necessitates adding nickel back into the alloy). The nickel comes at .05%. When it reaches .03%, it fails to function as a grain refiner. Also, the germanium is supposed to deplete, necessitating adding germanium back into the alloy. Is anybody aware of the specific studies that reference the nickel and germanium depletion?
Thanks muchly for your input.
