Title:
MULTILAYER WIRING BOARD AND PROBE CARD IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2017/191726
Kind Code:
A1
Abstract:
This invention is provided with: an insulating plate 41 comprising a plurality of insulating synthetic resin layers; wiring circuits 44a, 44b, 44c provided to the insulating plate 41; a thin-film resistor 46 formed so as to be embedded in the insulating plate 41, the thin-film resistor 46 being electrically connected to the wiring circuits 44a, 44b, 44c; a heat dissipation part 47 provided on one surface of the insulating plate so as to face the thin-film resistor 46 across some of the plurality of insulating synthetic resin layers, the heat dissipation part 47 having a thermal conductivity higher than that of the insulating plate 41; a pedestal part 48 formed so as to be embedded in the insulating plate 41, the pedestal part 48 being provided so as to face the thin-film resistor 46 on the side opposite the heat dissipation part 47 across some of the plurality of insulating synthetic resin layers and having a thermal conductivity higher than that of the insulating plate 41; and a heat dissipation-pedestal connection part 49 provided so as to connect the heat dissipation part 47 and the pedestal part 48, the heat dissipation-pedestal connection part 49 having a thermal conductivity higher than that of the insulating plate 41.
