Abstract

A support for a semiconductor device comprises a lead frame having a matrix of cranked conductors, which may be on an insulating substrate, with a recess being defined within the lead frame, the arrangement being such that by merely placing a correctly oriented device in the recess, and providing the required electrical interconnections between the device and the conductors, the device is accurately located in its required position on the lead frame.
