METHOD FOR MANUFACTURING OF COMPOSITE PRINTED CIRCUIT BOARD Russian patent published in 2014 - IPC H05K3/36 H05K3/40 

FIELD: electricity.

SUBSTANCE: in the method the unified blocks of printed-circuit boards, each of which is made of identical amount of printed-circuit boards of the first and second type. The blocks are connected among themselves two by two, and first of all one pair block is turned on 180 degrees with reference to the second pair block and the named blocks are joined by end faces. Each printed-circuit board of the first type of one pair block joined with the printed-circuit board of the second type of another pair block. The joint line along the whole length is covered by bars, which are fixed then to the printed-circuit boards of the first and second pair blocks. An obtained product is then separated into composite printed-circuit boards.

EFFECT: minimising the amount of operations for manufacture of composite printed-circuit boards.
