Patent attributes
An interposer bonding device 3 is intended for bonding an interposer 10 having an interposer-side terminal to a base circuit sheet 20 provided with a base-side terminal. The interposer bonding device 3 has a press anvil 31 that holds the base circuit sheet 20 on which the interposer 10 is laminated and a bonding head 32 that moves relatively with respect to the press anvil 31. The bonding head 32 has a pressing surface 320 that presses the rear surface of the interposer by abutting against this surface. The pressing surface 320 scans the rear surface of the interposer 10 by the relative movement of the bonding head 32 with respect to the press anvil 31 and presses the whole surface of the interposer-side terminal 12 toward the base circuit sheet 20.
