Abstract
Abstract A clip is formed from an electrically conductive cover having integral inwardly biased skirt portions depending along either side thereof. When the chip is engaged over the base of a semiconductor package the skirt portions electrically contact each of the several leaves depending from the base to maintain each of the leaves at the same electrical potential. Optionally the cover has an aperture therethrough to expose the area of the base which carries the integrated circuit chip.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
203 words
A single-piece ground clip for use in combination with a semi-conductor package, said package including a base member and integrated circuit chip carried on said base member and a plurality of leads extending downwardly from the periphery of said base member, said leads connected electrically to respective components of said chip, said ground clip comprising: a. a cover member formed of electrically conductive material sized to overlay said base member; b. skirt members formed integrally with said cover member and depending downwardly therefrom adapted to make electrical contact with each of said plurality of leads to maintain each of said leads at the same potential while said clip is engaged with said package; and c. means for detachably securing said ground clip to said semiconductor package such that the leads of said semi-conductor package can be electrically connected in the final intended circuit while said leads are still grounded by contact with said skirt members, said means comprising portions of said skirt members biased inwardly to make sliding frictional contact with said leads, allowing said leads to be exposed for connection in said final circuit and then allowing said ground clip to be detached from said semi-conductor package after said connection is effected.
Claim 2
Dependent Claim
203 words
A single-piece ground clip for use in combination with a semi-conductor package, said package including a base member and integrated circuit chip carried on said base member and a plurality of leads extending downwardly from the periphery of said base member, said leads connected electrically to respective components of said chip, said ground clip comprising: a. a cover member formed of electrically conductive material sized to overlay said base member; b. skirt members formed integrally with said cover member and depending downwardly therefrom adapted to make electrical contact with each of said plurality of leads to maintain each of said leads at the same potential while said clip is engaged with said package; and c. means for detachably securing said ground clip to said semiconductor package such that the leads of said semi-conductor package can be electrically connected in the final intended circuit while said leads are still grounded by contact with said skirt members, said means comprising portions of said skirt members biased inwardly to make sliding frictional contact with said leads, allowing said leads to be exposed for connection in said final circuit and then allowing said ground clip to be detached from said semi-conductor package after said connection is effected.
Claim 3
Dependent Claim
34 words
The ground clip of claim 1 wherein said cover member further includes means defining an aperture therein dimensioned to expose at least the portion of the base member upon which said chip is carried.
