Abstract:
1. An interposer bonding device for bonding an interposer to a base circuit sheet, the interposer having a semiconductor chip mounted on a sheet chip holding member and having an interposer-side terminal as a connection terminal extending from the semiconductor chip, the base circuit sheet formed from a sheet base member and provided with a base-side terminal on a surface thereof, the interposer bonding device comprising: a press anvil configured to hold the base circuit sheet and provided with a pressing surface that has a convex portion including a protrusion that protrudes toward the held base circuit sheet; and a bonding head provided with a pressing surface configured to press a surface of a sheet material by pressing against the surface, wherein, when supplying the base circuit sheet on which the interposer is laminated, in a configuration where the interposer-side terminal and the base-side terminal are facing each other with an adhesive having electrical insulating properties, the pressing surface is configured to scan a rear surface of the interposer according to the relative movement of the bonding head to the press anvil and to press the interposer-side terminal to the base-side terminal, wherein the protrusion is configured to shape part of the base-side terminal to form a protruding deformed portion that contacts directly with the interposer-side terminal, and a gap between both terminals with the adhesive remaining therein, corresponding to portions other than the protruding deformed portion in the base-side terminal, wherein the press anvil has a substantially cylindrical shape and is configured to hold, on an outer surface thereof, the base circuit sheet and to rotate around an axis center of the substantially cylindrical shape, and wherein the bonding head is configured to move relative to the interposer by the rotation of the press anvil.
