Abstract: A method for producing printed circuit board sets capable of being made, among other things, without adhesive, in flexible manner and with very small transverse connections with diameters of the order of 1 to 3 ?m. The method uses, as starting material for the printed circuit board set, a support element free of any copper layer.

The desired printed circuit board set is then completed according to the usual methods.
