Abstract:
1. A method of processing a plurality of integrated circuit (IC) packages, comprising: forming a plurality of individual IC packages from an array of attached IC packages; removing oxides from side surfaces of terminals of the individual IC packages before vertically stacking the individual IC packages having the terminals; wherein vertically stacking the individual IC packages having the terminals comprises: placing a first side of a first individual IC package onto a first side of a cover, where the first side of the first individual IC package includes terminals, placing a first side of a second individual IC package onto a second side of the cover opposite to the first side of the cover to form a first stack of individual IC packages, and placing the stack of individual IC packages on a second stack of individual IC packages; maintaining the first stack of individual IC packages and second stack of individual IC packages using a securing device; pre-heating the first stack and the second stack to a temperature less than a temperature of a solder bath; forming a solder coating on the side surfaces of terminals of the individual IC packages of the first stack and the second stack; and dismantling the first stack and the second stack and cleaning the plurality of individual IC packages.
