Abstract
The leads on a Semiconductor Package of the type having a generally round configuration and generally termed a header, are crimped into a conducting relationship for plating by means of an apparatus comprising a track type of conveyer for conveying the headers along a specific path, and a pair of rollers disposed on opposite sides of the track for engaging the leads as the header passes therebetween for crimping the leads together in a conducting relationship. The rollers comprise wheels mounted for rotation in opposite directions at different speeds, such that the header is rotated between the wheels but simultaneously moved in a linear direction along the conveyer.
