Method for attaching a semiconductor chip in a plastic encapsulant, optoelectronic semiconductor component and method for the production thereof

摘要

A radiation-emitting or -receiving semiconductor chip 9 is soft-soldered for mounting on a leadframe 2 over which a prefabricated plastic encapsulant 5, a so-called premolded package, is injection-molded. Through the use of a low-melting solder 3 applied in a layer thickness of less than 10 μm, the soldering process can be carried out largely without thermal damage to the plastic encapsulant 5.
