LAMINATED SUBSTRATE FOR MOUNTING ELECTRONIC PARTS

摘要

The invention relates to a laminated substrate producing method for mounting semiconductor chips, wherein at least respective metal and plastic structure films having respective different recurrent contour are laminated together in such a way that a material strip is obtained and said lamination is followed by perforations or cuttings, the inventive method is characterised by at least one of the following steps: A) the films are structured in such a way that the superposition thereof makes it possible to obtain the areas which are devoid of overlap through the total thickness thereof; B) the films are not laminated through the total thickness of the laminate in partly recurrent areas; and C) the reccurent cross-sections of the reccurent contours are curved from the surface of the laminated strip starting from said laminate.
