METHOD AND DEVICE FOR PRODUCING CONNECTION SUBSTRATES FOR ELECTRONIC COMPONENTS

摘要

According to a method for producing connection substrates for semiconductor chips, preferably PSGA (polymer stud grid array) substrates, a blank body (1), preferably a film, is heated and humps (3) and/or recesses are produced on at least one of its surfaces using an embossing roller. High temperature resistant thermoplastics, preferably LCPs (liquid crystal polymers), are used as the material for the substrate body. Their surface can preferably be provided with a metallic layer which is in turn provided with openings as an embossing aid.
