Abstract

Sandwich plates consisting of two conductive layers on the outside, enclosing a thermoplastic layer (a thermoplastic substrate with a printed circuit on both sides) can be spot welded by affecting a short-circuit between the outer conductors. This produces enough heat at the electrode contact ot melt the thermoplastic material. This can be displaced by electrode pressure and the spot weld can be completed. The short-circuit can be produced by a metal clamp, or by crimping the metal edges together or by a large auxiliary electrode with a separate current source.
