ABSTRACT:
A method for enhancing temporary solder ball connection comprises the application of thermal energy to the solder balls, heating them to a submelting "softening" temperature, whereby the compression force required to connect all balls in a BGA is achieved at much reduced force, avoiding damage to the package, insert, substrate and support apparatus. Several forms of heating apparatus, and temperature measuring apparatus, are disclosed.
