Abstract

EMC (Electromagnetic Compatibility) contact strips may be attached to closure points between computer frame hardware and panel hardware by a conductive thermosetting adhesive. The conductive adhesive is applied to a portion of the available attachment contact area of the strip. A pressure sensitive adhesive is applied to the remaining area. The latter adhesive provides semipermanent instantaneous bonding under pressure. The thermosetting adhesive cures to a permanent and secure bonding M H condition over a period of time.The pressure sensitive adhesive effectively replaces the jigs or clamps which are otherwise required to hold the contacting parts until the permanent bond cures.

Adhesively Fastened EMC Contact Strips

EMC (Electromagnetic Compatibility) contact strips may be attached to closure points between computer frame hardware and panel hardware by a conductive thermosetting adhesive. The conductive adhesive is applied to a portion of the available attachment contact area of the strip. A pressure sensitive adhesive is applied to the remaining area. The latter adhesive provides semipermanent instantaneous bonding under pressure. The thermosetting adhesive cures to a permanent and secure bonding M H condition over a period of time.The pressure sensitive adhesive effectively replaces the jigs or clamps which are otherwise required to hold the contacting parts until the permanent bond cures.

Example of useful adhesives:
a) Pressure sensitive:

1) Silicone

2) Acrylic

3) Synthetic Rubber
b) Thermosetting/conductive:

1) Epoxy

2) Urethane.
