Abstract
Abstract A carrier having a plurality of leads extending from the lateral sides thereof. The leads extend along the lateral side and over protuberances into depressions in the bottom of the carrier. Each of the depressions is separated by ribs from the other depressions. The ends of the leads disposed in the depressions are prevented from substantial movement by the rib to prevent contact with adjacent leads. At least some of the leads are provided with holes disposed adjacent to the exit of the leads from the enclosure of the carrier. The holes in the leads allow the leads greater flexibility at their portions close to the entrance of the leads into the enclosure. The leads are tapered along their length toward the protuberances. Further, the leads are separated by a width along the lateral side which is within the range of substantially the width of the leads to less than the width of the leads to prevent nesting.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
A carrier for an integrated circuit comprising: (a) an enclosure having said integrated circuit disposed therein and a top, bottom, and four flat lateral sides, and provided with a plurality of protuberances along each lateral side; (b) a plurality of leads, at least one lead extending from an end thereof located in said enclosure through each lateral side and along said lateral side toward said bottom, each lead extending over one of said protuberances and spaced from an adjacent lead by a distance within the range of substantially equal to the width of said lead to less than the width of said lead.
Claim 2
Dependent Claim
103 words
A carrier for an integrated circuit comprising: (a) an enclosure having said integrated circuit disposed therein and a top, bottom, and four flat lateral sides, and provided with a plurality of protuberances along each lateral side; (b) a plurality of leads, at least one lead extending from an end thereof located in said enclosure through each lateral side and along said lateral side toward said bottom, each lead extending over one of said protuberances and spaced from an adjacent lead by a distance within the range of substantially equal to the width of said lead to less than the width of said lead.
Claim 3
Dependent Claim
143 words
Carriers for integrated circuits, each carrier comprising: (a) an enclosure having said integrated circuit disposed therein and a top, bottom, and four flat lateral sides, and provided with a plurality of protuberances along each lateral side; and (b) a plurality of leads, at least one lead extending from each of said lateral sides toward said bottom, at least two adjacent leads extending approximately parallel from within said enclosure along one lateral side toward said bottom, each adjacent lead extending over one of said protuberances, said adjacent leads having approximately equal widths, one adjacent lead spaced from another adjacent lead by a distance within the range of from substantially equal to the width of said one adjacent lead to less than the width of said one adjacent lead to prevent nesting of a lead of another carrier between said one and another adjacent leads.
Claim 4
Dependent Claim
143 words
Carriers for integrated circuits, each carrier comprising: (a) an enclosure having said integrated circuit disposed therein and a top, bottom, and four flat lateral sides, and provided with a plurality of protuberances along each lateral side; and (b) a plurality of leads, at least one lead extending from each of said lateral sides toward said bottom, at least two adjacent leads extending approximately parallel from within said enclosure along one lateral side toward said bottom, each adjacent lead extending over one of said protuberances, said adjacent leads having approximately equal widths, one adjacent lead spaced from another adjacent lead by a distance within the range of from substantially equal to the width of said one adjacent lead to less than the width of said one adjacent lead to prevent nesting of a lead of another carrier between said one and another adjacent leads.
