The network forma barrel where the electric patchboard

摘要

PROBLEM TO BE SOLVED: To provide an electric wiring board which can obtain a wiring circuit, without performing a solder bonding, and to provide a method of manufacturing this.;SOLUTION: The electric wiring board is manufactured by a step of forming a network form cylinder 2, in which a plurality of conductive loop wires 1 are connected integrally in a plurality of circular direction positions, a step of forming network form sheets 3 and 4 in which the network form cylinders 2 are crushed and laminated flat in the radial direction, a step of interposing an insulating sheet 5 inside the network form sheets 3 and 4, and a step of forming defect parts 6 in the circular direction position of the conductive loops 1a of the network form sheets 3 and 4. Consequently, the electric wiring board is manufactured, and the semiconductor chip 7 can be bonded directly to the conduction loop 1a of the network form sheet 3.;COPYRIGHT: (C)2006,JPO&NCIPI
