Insert-Moulded Lead Frame and Method for the Production Thereof

摘要

An encapsulated lead frame has a core element with multiple elongated conductor tracks arranged next to one another. The lead frame also has first partial encapsulations formed by a first encapsulation of the core element in first sub-regions and second partial encapsulations formed by a second encapsulation of the core element in second sub-regions. The first and second partial encapsulations enclose the core element as an overall encapsulation. The first partial regions are spaced apart from one another and each of the first partial encapsulations respectively surrounds only one single conductor track. This configuration avoids gaps that may form at interfaces between a first and second partial encapsulation, may extend between two adjacent conductor tracks, and may allow conductive fluid to accumulate therein and form short-circuits between adjacent conductor tracks. The encapsulated frame is used in a transmission control device. A method for producing an encapsulated lead frame is disclosed.

主权项

1. An insert-molded lead frame, comprising:
a core element with a plurality of elongate conductor tracks arranged next to one another; first partial insert-moldings formed by a first insert molding of the core element on first partial regions of the core element; second partial insert-moldings formed by a second insert molding of the core element on second partial regions of the core element, wherein the first partial insert moldings and the second partial insert moldings together form a complete insert-molding that completely encases the core element, and wherein adjacent first partial regions are spaced apart from one another, and each of the first partial insert-moldings in each case surrounds only one individual conductor track.
