Abstract: A machine for blanking an integrated circuit chip from a segment of a film strip held in a fixture, forming its leads, and placing the chip on a multilayer substrate. The fixtures are stacked in a magazine which is mounted on the machine. A transfer mechanism transfers one fixture at a time from the magazine to a punch press where the IC chip is blanked from its film segment, and its leads are formed. The punch is retracted, and a multilayer substrate, which is mounted on an X-Y table, is positioned by the table under the punch so that the excised chip is directly above a chip pad and the chip leads are above the chip lead pads of a predetermined chip pad. The punch is lowered to position the chip on its chip pad. The substrate is coated with an adhesive flux to retain the chips and their leads in place. The punch is retracted and the X-Y table is moved to clear the punch press. A microcomputer controls the machine.

Abstract: A reusable fixture for a segment of a film strip having a flexible beam lead frame mounted on the segment and an integrated circuit chip bonded to the inner portions of the leads of the lead frame. The fixture is made from an integral laminar layer of a suitable material. The improvements are in providing a plurality of pairs of projections with protuberances which overlie, to a slight degree, the attachment webs of a segment. The fixture is also provided with detachment openings to provide access to the attachment webs which detachment openings facilitate removal of a segment from the fixture.

Abstract: A sequencer for assembling into a transferee magazine predetermined numbers of fixtures from a predetermined plurality of transferor magazines, each of which transferor magazines is adapted to hold a plurality of fixtures. Each of the fixtures stacked in a transferor magazine holds an integrated circuit (IC) chip of the same type. The transferor magazines are removably mounted on transferor bases mounted on a support member. Positoning means are also mounted on the support member and a transferee magazine is removably mounted on a transferee base secured to the positioning means. A transfer mechanism is mounted on the positioning means to transfer a fixture from a transferor magazine to the transferee magazine when the transferee magazine is in fixture transfer position with respect to a transferor magazine.
