Abstract:
1. Method to make a multilayer expansion card for connecting an apparatus or device to an electronic apparatus, comprising a first part, intended principally for connection, having a thickness coherent with requirements of size for connection to standard slots of a mother card of the electronic apparatus, and a second part, intended principally for management of functions of the expansion card and for processing, and hence electronics of the expansion card, having a greater thickness with respect to said first part to contain a correspondingly greater number of layers intended for management of a high density of electronic signals, said method comprising the steps of: a first step wherein a first sub-set is made, of a thickness substantially equal to the thickness of a connection part of said expansion card and of a plane size substantially equal to the plane size of the entire final expansion card; a second step wherein a second sub-set is made, of a thickness substantially equal to the difference between the total thickness of said expansion card and the thickness of said connection part, and which at the end of the production process will have a plane size less than that of said first sub-set, so that the part dedicated to connection remains exposed; a third step wherein the two sub-sets are assembled together by means of pressing.
