  • Solder process for enhancing reliability of multilayer hybrid circuits
    Patent number: 5803343
    Abstract: A thick film hybrid multilayer circuit characterized by circuit components that are electrically interconnected with a multilayer structure composed of multiple layers of conductors interlaid with layers of a dielectric material in order to achieve high component density. The circuit components of the hybrid circuit are bonded to the multilayer structure with a novel soldering technique employing multiple solder compositions, which reduces the occurrence of dielectric fatigue cracking from thermal cycling. As a result, the multilayer structure exhibits significantly enhanced thermal fatigue resistance.
