R&D and innovation
In-house metallurgical expertise
IPS has a long-time metallurgical experience of electronic grade solder alloys ( classical SnPb, SnPbAg or SAC ) as well as higher melting point alloys like Pb-rich, SnBi, SnAgBi, SnZn or SnZnBi for example and each different request has potential enhancement doping solution.
Doping optimization lead solder joint to enhanced results in various metallurgical characteristics like ductility, shear or pull strength, resistance to mechanical or thermal shocks that are key assets for certain applications.
Intermetallic growth condition depends on dopant selection
