METHOD FOR PRODUCING CIRCUIT BOARDS COMPRISING ELECTRONIC, OPTICAL AND FUNCTIONAL FEATURES

摘要

An object of this invention is a method for producing circuit boards having electronic, optical and functional features, wherein the surface of the base plate (1) of the circuit board is provided with metallization (7, 8), an insulating protective layer upon the metallization, the next conductive layer (9, 10) upon the protective layer, etc., until the needed number of layers has been deposited one upon the other. The base plate (1) is produced of a plate preform, the handling of which in the production of a circuit board is performed from the processing location in the middle of the plate preform, such as a hole (2).
