ENCRE RESISTANTE A BASE D'OXYDE D'INDIUM, ET SON UTILISATION, DANS DES STRUCTURES ELECTRIQUES, SUR DES SUBSTRATS METALLIQUES REVETUS DE PORCELAINE

摘要

A description is given of a thick-film resistor ink for producing a resistor film on a printed circuit board. The object is to improve the temperature coefficient of the resistance value of such resistor inks. For this purpose, the resistor ink consists of indium oxide, magnesium oxide, a barium calcium borosilicate glass compound and a suitable organic carrier substance. The temperature coefficient of the resistance can be adjusted with the aid of the magnesium oxide.
