Abstract
A technique for providing controlled adhesion of a portion of a printed conductor to a circuit board employs an inhibitor layer between the circuit board and the portion of the printed conductor where such controlled adhesion is desired. The inhibitor layer is formed using a mixture of finely divided alumina powder and a glass frit, which are both suspended in an organic screening agent. An electrical module connected between controllably adherent conductor portions is thereby able to move to relative mechanical stresses.
