Abstract

The drawings depict a module cap configured to serve as a comprehensive physical interface for an integrated circuit assembly. Principal functions include substrate reinforcement, connector engagement, heat transfer and protection of the module interior. These are achieved as follows: 1. A chip-joined substrate (shown separately) is seated within the cap with its top (chip-joined) surface resting against the seating ledge 1. Fixturization (not shown) is used to establish a precise relationship between the array of substrate I/O pins and the working surfaces provided on the cap. Bonding is accomplished by setting of an adhesive applied between the sidewalls of the substrate and the cap while the two are held in the fixture. 2.

Bonding is accomplished by setting of an adhesive applied between the sidewalls of the substrate and the cap while the two are held in the fixture. 2. The resultant module mates with a machine by first lowering it vertically into a receptacle (not shown), then driving it horizontally to engage its I/O pins with the contact springs of a connector. These motions are governed by the tabs provided along two opposite sides of the cap. During descent, outer tabs 2, riding in channels in the recep

With the module so seated, a locking bale affixed to the receptacle is rotated, causing studs on its arms to work against driving surfaces 4a on one set of the inner tabs 4. This action moves the module horizontally toward engagement. As movement progresses, retention fin...
