Abstract

By the process a larger contact area is afforded for a conducting epoxy 10 interconnecting printed conductors 12, 13 and 14 laid down in conducting ink on inexpensive card stock 16 not thermally susceptible to strain. This is accomplished by: (1) Interleaving the card stock 16 with thermoplastic sheets 18. (2) Deforming both the card stock 16 and the thermoplastic sheets upon punching. (3) Heating the sandwich and reforming the thermoplastic sheets 18 leaving dimples 20 between the card stock 16 and the sheets 18 around the holes punched. (4) Filling the void with conducting epoxy 10.

Printed Circuit Packaging

By the process a larger contact area is afforded for a conducting epoxy 10 interconnecting printed conductors 12, 13 and 14 laid down in conducting ink on inexpensive card stock 16 not thermally susceptible to strain. This is accomplished by:
(1) Interleaving the card stock 16 with thermoplastic sheets 18.
(2) Deforming both the card stock 16 and the thermoplastic sheets

upon punching.
(3) Heating the sandwich and reforming the thermoplastic sheets

18 leaving dimples 20 between the card stock 16 and the

sheets 18 around the holes punched.
(4) Filling the void with conducting epoxy 10.

The printed conductors separate from the card stock 16 and follow the thermoplastic sheets 18 as shown. This does not detract from the quality of the product nor from the efficacy of the process by which it is obtained.
