Description
In the soldering process, nickel has the effect of a diffusion barrier and accumulates itself in the solder joint’s intermetallic layer. Thereby a reduction is to be expected in the long-tem. FELDER nickel concentrate “Ni3” sets the Ni-content in wave, selective and HASL machines back to the required values. “Ni3” is also used for the conversion of lead-free standard solders to FELDER NiGe-electronic solders.
