Abstract

Abstract A carrier for an IC package having a plurality of IC leads projecting in parallel sidewise from at least two lateral side surfaces thereof comprises a carrier substrate including a section for accommodating the IC package therein and a plurality of grooves formed in the central surface of the carrier substrate for accommodating therein the IC leads and supporting the lower surfaces of the IC leads on the bottoms thereof when the IC package has been accommodated in the section. Also included is an IC package support detachably mounted at a position on the carrier substrate, disengageably engaged at another position with the carrier substrate and comprising at least two IC lead retaining bars which are disposed so as to engage the upper surfaces of the IC leads for retaining against the lower surfaces of the bars the upper surfaces of the IC leads when the IC package support has been engaged with the carrier substrate having the IC package accommodated in the section thereof.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 282 words
A carrier of an IC package having a plurality of IC leads projecting in parallel sidewise from at least two lateral side surfaces thereof, which comprises: a carrier substrate including a section for accommodating the IC package therein and a plurality of grooves formed in at least two lateral side portions of the upper surface of said carrier substrate for accommodating therein the plurality of IC leads and supporting the lower surfaces of the plurality of IC leads on the bottoms thereof when the IC package has been accommodated in said section; IC package supporting means hingedly mounted for rotation at a position on said carrier substrate, disengageably engaged at another position with said carrier substrate and comprising at least two IC lead retaining bars which extend along said two lateral side portions and engage the upper surfaces of the plurality of IC leads for retaining against the lower surfaces of the bars the upper surfaces of the plurality of IC leads when said IC package supporting means has been engaged with said carrier substrate having the IC package accommodated in said section thereof; said at least two IC lead retaining bars having free outer ends, said free outer ends of said bars having engaging pawls, and said free outer ends being elastically shiftable toward and away from each other; and said upper surface of said carrier substrate has engaging means for engaging said pawls and for shifting said free outer ends of said bars toward each other when said bars are rotated against the upper surface of said carrier substrate, whereby said pawls of said free outer ends are engageable and disengageable with said carrier substrate for retaining the IC package.
Claim 2
Dependent Claim 282 words
A carrier of an IC package having a plurality of IC leads projecting in parallel sidewise from at least two lateral side surfaces thereof, which comprises: a carrier substrate including a section for accommodating the IC package therein and a plurality of grooves formed in at least two lateral side portions of the upper surface of said carrier substrate for accommodating therein the plurality of IC leads and supporting the lower surfaces of the plurality of IC leads on the bottoms thereof when the IC package has been accommodated in said section; IC package supporting means hingedly mounted for rotation at a position on said carrier substrate, disengageably engaged at another position with said carrier substrate and comprising at least two IC lead retaining bars which extend along said two lateral side portions and engage the upper surfaces of the plurality of IC leads for retaining against the lower surfaces of the bars the upper surfaces of the plurality of IC leads when said IC package supporting means has been engaged with said carrier substrate having the IC package accommodated in said section thereof; said at least two IC lead retaining bars having free outer ends, said free outer ends of said bars having engaging pawls, and said free outer ends being elastically shiftable toward and away from each other; and said upper surface of said carrier substrate has engaging means for engaging said pawls and for shifting said free outer ends of said bars toward each other when said bars are rotated against the upper surface of said carrier substrate, whereby said pawls of said free outer ends are engageable and disengageable with said carrier substrate for retaining the IC package.
Claim 3
Dependent Claim 29 words
The IC package carrier of claim 1, wherein the free outer ends of said at least two IC lead retaining bars further comprise inwardly extending IC lead retaining pieces.
