Abstract
A process for producing an automatic-machine-bondable LTCC (Low Temperature Cofired Ceramics) circuit carrier includes the steps of applying a conductive paste having a glass content of less than 1.0 percent by weight onto a ceramic substrate having a glass content of at least 30 percent by weight, in order to form contact pads. The circuit carrier is fired such that glass melts out of the ceramic substrate and causes an adhesion between the conductive paste and the ceramic substrate. A ceramic circuit carrier has adhesion-promoting glass between the ceramic substrate and the conductive paste, wherein the adhesion-promoting glass originates from the ceramic substrate.
