Abstract:
1. A method of forming an integrated circuit (IC) package, comprising: removing oxides from a cut side surface of a terminal of a singulated IC package, wherein the underside of the terminal comprises a solderable coating; placing the underside of the IC package on a cover or seal, the cover or seal substantially covering an underside of the terminal of the IC package and substantially exposing the cut side surface of the terminal; and forming a solder coating on the cut side surface of the terminal of the IC package while covering the underside of the terminal of the IC package; pre-heating the IC package to a temperature substantially the same as but less than a temperature of a solder bath; and subjecting the cut side surface of the terminal of the IC package to the solder bath to form the solder coating while protecting the solderable coating on the underside of the terminal by the cover or seal from the subsequent solder coating on the cut side surface of the terminal of the IC package.
