Connector

A connector is described which bridges the gap between pads 7 of two electronic devices 1 and 2 (Fig. 1). The connector is produced as follows.

Tape 3 (Fig. 2) with copper lines 4 perpendicular to its longitudinal axis is cut into stripes 5, the width of which roughly equals the height of the gap between the electronic devices. One stripe 5 is wrapped around frame 6 (Fig. 3) several times. The shape of frame 6 corresponds to that of the pad arrays to be electrically connected. The inside of frame 6 is supported on a frame-shaped cushion 8 having a U-shaped cross-section. Fig. 4 is a cross-sectional view of the connector.

A heat process in a clamp glues the layers of stripe 5 together. The top and the bottom of the layers of stripe 5 are cut to form a flat surface with the exposed copper lines 4. The copper is applied by electroless deposition, with an overlying gold layer protecting the connector against corrosion. The connector has the following advantages. 1) No parts have to be mounted to the two devices 1 and 2

to be electrically connected.

2) The connection is not damaged by misplacement.

3) A large number of connections are possible in a

small area by adjusting the two opposing devices 1

and 2.

4) The connector may be readily produced by providing

a low-cost interconnection.

5) The connector is a zero insertion force connector.
