Abstract

Electrical connection to conductors 1 of thin-film circuit 2 is made by overlay 3. The latter has circuit conductors 4 underlying a layer of transparent insulation 5. Overlay 3 is stretched by bonded metal strip 6 tensioned by screws 7. Strip 6 is slotted to show ends of conductors 3. Registration results from adjusting screws 7 together to align centers of circuit 2 and overlay 3 and subsequently adjusting screws 7 differentially to vary the pitch of conductors 3. Variation in shrinkage of overlay 3 during manufacture is compensated for by pretensioning strip 6 before bonding to layer 5 by amount appropriate to degree of shrinkage.
