Abstract
To further reduce the manufacturing costs of semiconductor devices, such as TO-92 transistors or thyristors, a prefabricated plastic can or housing is filled with cast resin, and the chip, together with its leads and a synthetic-resin cover, is inserted into the cast resin and the can, with portions of the leads engaging a groove in the can. The apparatus for inserting the chips, etc., into the cans includes a feed rail for the cans, a centering slide, and a swivelling gripper onto which the cans are pushed by the centering slide. When rotated, the swivelling gripper slips the cans over the chips mounted on a lead frame moving above the swivelling gripper.
