Semiconductor devices are mounted on corresponding lead frames by being inserted into apertures of a masking member in a desired registration with the lead frame strip.

Method of manufacturing semi-conductor devices

Apparatus in which gold tape is to be servered and placed on selected parts of support members of supports for semiconductor devices has means to feed the tape to severing means including a reciprocatable dog to engage the tape. The dog may pierce or indent the tape, or may frictionally engage the tape.

Manufacture of supports for semiconductor devices

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.
