Terminals welded onto metal coating of condenser foil - by pressure after previous heating in separate stage

摘要

A method of attaching connecting elements to metal-coated, thermoplastics insulating sheet, esp. condenser foil, consists of first heating the elements in a heating zone and then placing them above the insulating foil and applying pressure to weld them to the metal coating. Since the elements are not being pushed into the foil while they undergo electrical resistance heating, accurate and reproducible temps. can be obtd.
