Abstract

An electronic component with leads attached is cleaned, a layer of an epoxy or epoxy-reactive silane is applied and cured, and then the package material is molded on. The silane layer bonds the component to the package and provides a fluid-tight seal therebetween. The silane is gamma-glycidoxypropyl- or gamma-aminopropyltrimethoxy or triethoxy silane.
