Abstract

There is disclosed a process for the assembly of an electronic package in which the outer lead ends of a leadframe are solderable to external circuitry without the necessity of a tin or solder coat. An oxidation resistant layer is deposited on the leadframe prior to package assembly. The oxidation resistant layer is removed prior to outer lead soldering providing a clean, oxide free metallic surface for soldering.
