MULTIPLE LAYER PRINTED CIRCUIT BOARD Russian patent published in 1995 - IPC

FIELD: radio engineering. SUBSTANCE: surface of flexible base is covered with foil. Picture with wires and contact places which structure is ridge- shaped and which are arranged in rows and columns is made on this surface. All contact places on base are connected to single electric circuit. Bases are joined to a packet, each bases is separated with dielectric spacer which have holes in points where contact places are made. Bases in packet are arranged so that ridge-shaped structures of contact places are turned at angle 90 to one another. Packet with all bases with dielectric spacers is positioned to rigid support. Packet of bases can be produced by flopping single base. Shape of produced contact places and their relative position should provide reliable electric contact. EFFECT: increased functional capabilities. 3 cl, 5 dwg
