ABSTRACT:
The invention relates to a method for the production of glass-coated electric components, wherein the components are, inter alia, passivated by the application of the glass. The lead-free glass used is not affected through purification and processing steps and the electric component is protected from mechanical damaging and other detrimental influences, such as impurities. Further, the method remarkably helps to stabilize the electrical properties of the components. Inter alia, a sufficient acid resistance is achieved and it results in an improvement of the expansion adjustment of the glass.
