The known switching panel is mainly for radio-electronic equipment, containing a printing array on which integrated circuits, power lines and contacts are placed. external and internal switching 11. ..

However, the well-known panel has: an insufficiently high density of the arrangement of the radio-radio electronic items. : G

The purpose of the invention is to increase the density of the layout of the elektronyoelemen- 15

The goal is achieved: in the switching panel containing the printed circuit board, there are integrated circuits located on the lirotppofl. Food tires are made with contact points. The internal commutation contacts are made one-sided and are placed on the power rails with a pitch corresponding to the pitch of the outputs of electrical radio elements, and the one-sided contacts of the tires are installed

in one row and electrically connected with contact pads.

The commutator junction contains a printed circuit board 1, according to which it has installed two-sided contacts 2, and the screening {general Layers, except for the damn; circuits - tires 3 and 4 feed and run. with internal contact switching 5. In the board, they are made with a certain grrrr then through: rtyo 5th b., Between which are located; 7. Outdoor 8; and internal 9 7 sredieny with; 3,: and 4 pads with jumpers 10, with slab 9 connected to the contact pads 11 on the outer surfaces of the tires 7 by means of metallization of the holes 12. On the outer surfaces. 7, the contact pads 13 for the outputs of the integrated circuits 14 are etched. The contact pads 13 are connected to one-sided contacts 15. There are insulating gaskets 16j 17 between the tires, 7 and the board 1 17. One-sided contacts 15 are connected to two-sided contacts 2 with removable mounting ib. Contacts 5 are energized by bus 3, jumpers 10 and layer 8 of bus 7, which are supplied to the output of the integrated circuit. Similarly, on the opposite side of the panel, contacts 5 are connected to earth and through bus 4, jumpers 10, layer 9 and pad 11 to the earth of the integrated circuit. The signal outputs of the integrated circuits are connected both with each other and with the contacts 2 used for the electrical connection between the switching panels by means of surround installation 18, which passes through the apertures 6 and connects the signal outputs of the integrated circuits located on both sides of the printed circuit board 1. At the same time, the holes 6 serve to fasten the mounting 18 to the printed circuit board 1. The invention makes it possible to reject expensive and unrepairable multi-layer printed wiring to ensure that the route is easy to change. ovki when adjusting patch panel 8 move to hydrochloric multilayer printed circuit board for mass production. The switch panel is mainly for electronic equipment, containing a printed circuit board on which integrated circuits, power buses and contacts for external and internal switching are placed, characterized in that, in order to increase the density of the arrangement of electrical radio elements, the power buses are located on both sides of the board and are equipped with contact pads, with the radio-electronic elements placed on the power buses, and the internal co-switching contacts are made one-sided and placed on the power buses, with a pitch ohm., corresponding to the pitch of the location of the terminals of the radio radio elements, and the one-sided contacts of the tires are installed in one row and electrically connected to the contact pads.
