INSTALLATION FOR PRODUCING A CIRCUIT BOARD COMPRISING ADDITIONAL COPPER WIRING ELEMENTS THAT ARE INTEGRATED AND BROUGHT INTO CONTACT BY ULTRASOUND

摘要

The invention relates to an installation for producing a circuit board comprising at least one additional electrically conductive structure that is in the form of a round or rectangular electrically conductive wiring element (4), in particular in the form of an elongate copper element or element containing copper, as an additional element, that is brought into contact by ultrasound at least on one part of the sheet on the copper film elements (2) and in another circuit board production method, is integrated into a circuit board by means of lamination. According to the invention, a horizontal and/or vertical sonotrode head with an ultrasound generator (12) is arranged on a table (15) and can be displaced in relation to said table by NC control and the wiring element (4) having a round or rectangular cross-section is guided from a roll (7) by a feed system with a notching device (12) and a separation device. The sonotrode head comprises a holding device which, during each operation, maintains the wiring element in a planar manner on the copper film surface and the sonotrode head can pivot in such a manner that the wiring elements can be stacked at an angle and the sonotrode tool can be changed manually or totally automatically and the sonotrode tool is flat and is made of titanium and/or other alloy metallic materials enabling the surface of a copper film to be partially cleaned and a passivation layer can be removed by oxidation.
