Abstract

Abstract An improved film carrier for affixing both two and three layer films used in tape automated bonding processes for the manufacture of semiconductor devices is disclosed. The carrier uses pegs to substantially match the sprocket holes in the film, thereby eliminating distortion in the film or the leads wires affixed in the film caused by prior art structures which force the film strips between holes to be bent in placing the film in the carrier.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 207 words
An improved film carrier for film having serially arrayed laterally opposed sprocket holes disposed thereon, said film being utilized in the manufacture of semiconductor devices, said film carrier comprising: a main frame member having an opening extending therethrough; a snap in film carrier and locator plate having alignment pins extending therefrom, said pins being positioned for mating engagement with said sprocket holes in said film, said alignment pins being sized relative to said sprocket holes in such a manner that said film may float about the true center of said film carrier and locator plate, said film carrier and locator plate further having a pair of opposed center line holes positioned for insertion of process tooling pins, said film carrier and locator plate having a central aperture extending therethrough adapted for performing lead bonding of a semiconductor device to said film; and a cover plate constructed and arranged for mating engagement with said film carrier and locator plate so as to capture a single film frame within said film carrier and locator plate by interlocking with said alignment pins, said cover plate having an aperture extending therethrough for subsequent lead bonding and having a pair of opposed center line sprocket holes for reception of processing tooling pins.
