- Integrated circuit devices commonly utilize a construction in which the semiconductor integrated circuit chip is mounted upon an insulator base with a plurality of relatively thin electrical connector leads projecting from the base to provide for connection of the device to external circuits.
- One common construction comprises a dual in-line package, in which the leads protrude from the opposite sides of the device and are bent at right angles, in a common direction, to afford mounting pins for the device. For example, twenty leads may extend from each of two opposed sides for a forty lead device. Devices of this kind are difficult to manufacture, particularly becuase of the need to bend the leads; breakage of the leads is a major source of. trouble and often causes a high rejection rate., The leads may also be broken during testing and shipping, even when a protective carrier is employed, and may be easily damaged in installation. Since the integrated circuits are quite expensive, the problems presented are of a serious nature.
- thesemiconductor chip is mounted upon an insulator base having a plurality of flat conductive pads along one edge-of the base.
- the device can then be inserted a short distance into a mounting slot in an edge-mount connector to connect the integrated circuit to external circuits.
- the edge of the base for the integrated circuit device provides some physical support for the device in addition to affording conductive elements for engagement with contacts in the connector.
- Edge-mount devices of this kind do not have the problems associated with those empploying external leads. However, the devices are usually quite thin and brittle and can be damaged unless adequately supported.
- edge-mount construction engages the contacts of the connector along only one edge, it is usually necessary to make all connections from the integrated circuit chip to individual conductive pads along that edge, resulting in rather difficult problems in the design of a pattern of interconnecting conductors. This tends to require a grossly elongated base with lengthy interconnecting conductors and with an increased possibility of undesired coupling between the conductors.
- More recently developed forms of electrical connector for an integrated circuit device are used with integrated circuit devices in which the electrical connections are provided by conductive pads disposed along two opposed sides of one surface of the insulator base for the device.
- the integrated circuit device is clamped between an insulator base and an insulator cover.
- the base includes a plurality of individual metal contacts, one for each conductive pad on the integrated circuit device; these electrical contacts may be of relatively rigid and strong construction, eliminating the problems associated with external leads in convenconnectors usually require at least some tools for mounting or removing an integrated circuit device from the connector.
- the connectors may permit improper mounting of the integrated circuit, leading to possible damage to the integrated circuit device or to other difficulties when used by unskilled manufacturing or repair personnel.
- a particular object of the invention is to provide a new and improved electrical connector for an integrated circuit device that effectively encloses and protects the device but that requires no tools for either removal or insertion of the integrated circuit device.

- a specific object of the invention is to provide a new and improved electrical connector for an integrated circuit device which incorporates orientation means for orienting the integrated circuit device, between a cover member and a base member, in a single fixed position and that does not permit improper mounting of the integrated circuit in the connector. More specifically, the orientation means precludes mis-orientation by way of reversal end-to-end, reversal side-to-side, or reversal face-to-face.
- a specific object of the invention is to provide a new and improved electrical connector for a flat integrated circuit device that is inherently inexpensive to manufacture, requires no particular skill or training for use, yet affords long term reliability coupled with full mechanical protection for the integrated circuit device.
- the present invention relates to an electrical connector for supporting and for completing electrical connections to a flat integrated circuit device having a plurality of electrically conductive pads arranged in a predetermined pattern along at least two opposed sides of a substantially planar connection surface.
- the connector comprises a unitary, one-piece insulator base affording two substantially coplanar upwardly facing locating surfaces that correspond generally in size and configuration to the aforementioned opposed sides of the connection surface on the integrated circuit device.

- the connector also includes orientation means comprising at least two posts, each formed integrally with one of the base and cover members and each projecting into an opening in the other of those two members. These posts orient an integrated circuit device between the cover member and the base member in a single fixed position with each contact element engaging one conductive pad on the integrated circuit device in firm pressure contact when the cover is closed and latched.
