Abstract
Abstract Disclosed is a modular system including a systems carrier, a test carrier and a systems connector for protecting an integrated circuit package during handling, testing, transportation and use. The system carrier comprises a frame with a large center opening to receive the package body and grooves to receive the package leads, and a bracket positionable on the frame to secure the package within the frame. This system carrier and the integrated circuit package become one unit which fits within the test carrier whose outside dimensions are determined by the testing machine in which the test carrier is positioned. The system carrier with its integrated circuit package also fits into the system connector which has leads for connecting the package leads to other conductors such as on a printed circuit board in an electronic system. The system connector also has means for retaining the system carrier and its package within the system connector and for maintaining electrical contact between the package and the remainder of the system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
206 words
A modular system for use with an integrated circuit flat-package having a body with four orthogonal sides and substantially straight leads extending laterally from said four sides of said body, said modular system comprising: a carrier frame having four orthogonal sides defining a hole for receiving said body of said flat-package, said four sides having grooves extending outwardly from said hole for receiving said leads; means for attaching said flat-package to said carrier frame, with said body being in said carrier frame hole and said substantially straight leads being in said grooves to prevent damage to said leads during handling; a system connector having four orthogonal sides for overlying a printed circuit board surface, said system connector sides defining a hole that also overlies said printed circuit board surface for receiving said carrier frame with said flat-package attached thereto; electrical conductors in said system connector for rigid attachment to said printed circuit board surface and aligned in said four system connector sides with said leads in said carrier frame grooves; said system connector including tab means for engaging said carrier frame to replaceably secure said carrier frame and attached flat-package in said hole of said system connector with said electrical conductors in contact with said leads.
Claim 2
Dependent Claim
206 words
A modular system for use with an integrated circuit flat-package having a body with four orthogonal sides and substantially straight leads extending laterally from said four sides of said body, said modular system comprising: a carrier frame having four orthogonal sides defining a hole for receiving said body of said flat-package, said four sides having grooves extending outwardly from said hole for receiving said leads; means for attaching said flat-package to said carrier frame, with said body being in said carrier frame hole and said substantially straight leads being in said grooves to prevent damage to said leads during handling; a system connector having four orthogonal sides for overlying a printed circuit board surface, said system connector sides defining a hole that also overlies said printed circuit board surface for receiving said carrier frame with said flat-package attached thereto; electrical conductors in said system connector for rigid attachment to said printed circuit board surface and aligned in said four system connector sides with said leads in said carrier frame grooves; said system connector including tab means for engaging said carrier frame to replaceably secure said carrier frame and attached flat-package in said hole of said system connector with said electrical conductors in contact with said leads.
Claim 3
Dependent Claim
87 words
The system as claimed in claim 1 and further including a test carrier having a large center opening for receiving said carrier frame with its integrated circuit package attached thereto, and means for engaging said carrier frame for holding said integrated circuit package in the test carrier while exposing said leads in said grooves, the outer dimension of said test carrier being adapted to fit a test machine on which the test carrier is positioned and which makes electrical contact to said exposed leads in said grooves.
Claim 4
Dependent Claim
33 words
The system as claimed in claim 2, wherein said system connector further includes contacts extending through a plurality of openings in said system connector to provide test probe points for each package lead.
Claim 5
Dependent Claim
17 words
The system as claimed in claim 1, wherein said tab means is integral with said system connector.
Claim 6
Dependent Claim
28 words
The system as claimed in claim 1, wherein said tab means is slidably connected in said systems connector and resiliently biased toward said hole in said system connector.
Claim 7
Dependent Claim
28 words
The system as claimed in claim 1, wherein said tab means is pivotally connected to said system connector and resiliently biased toward said hole in said system connector.
