Solder Spheres

Lead-free and leaded solder spheres

Solder spheres from MARTIN are optimal to use for Reballing of BGA and CSP chips. They are available in various sizes. Their material composition equals standard alloys in electric manufacturing (lead free: Sn96,5Ag3Cu0,5 / leaded: Sn63Pb37). Hence, processes parameter for i.e. reflow can be used for reballed SMDs in same manner as for new ones. 

As a result of a special and unique manufacturing procedures our solder spheres have best surface quality and repeatable sphere shape. Both are important parameter for easy usage with stencils and stable reballing processes. 

To keep the wetting properties at its best - also on the used pads - MARTIN solder spheres are packed, stored and delivered under dry & intert (oxygen free) Argon gas. By this the creation of the unwanted oxide onto the sphere surfaces is suppressed: Thereofre the number of voids is little in solder joints and the electrical properties are very good.
