Method for producing electrically conductive bushings in enamelled metal plates

摘要

In the case of the method, the metal plate (2) is first perforated, is then deburred and is subsequently enamelled. Thereafter, the enamelled hole walls are provided with a metal coating (11) by the use of thin-film technology. Connecting pins (7) which can be soldered are then inserted into the metallised holes and are mounted in a gas-tight manner in the holes by means of solder (12). According to a deviating method, the metallisation of the hole walls is carried out in that an electrically conductive paste is introduced into the enamelled holes by suction by means of a vacuum, and the metal coating (11) is subsequently produced by burning the paste into the enamel layer (1). <IMAGE>
