Abstract:
1. A method of manufacturing an electronic device, the electronic device comprising: a mount substrate having a patterned conductor exposed on one of surfaces of the mount substrate; and an electronic component having a connection electrode formed on one of surfaces of the electronic component, the one of the surfaces of the electronic component that has the connection electrode formed thereon being disposed to face toward the one of the surfaces of the mount substrate, the connection electrode being electrically connected and mechanically bonded to the patterned conductor of the mount substrate, the method comprising the steps of: disposing the electronic component and the mount substrate such that the one of the surfaces of the electronic component faces toward the one of the surfaces of the mount substrate, and electrically connecting and mechanically bonding the connection electrode of the electronic component to the patterned conductor of the mount substrate; placing a resin film over the electronic component and the mount substrate; deforming the resin film by sucking a gas existing on an electronic-component side of the mount substrate from the other side of the mount substrate through a hole provided in the mount substrate, such that the resin film covers the electronic component and the mount substrate in close contact with a surface of the electronic component that is farther from the mount substrate and with a part of the one of the surfaces of the mount substrate, the part being located around the electronic component; and adhering the resin film to the mount substrate by heating the resin film to cause the resin film to fluidize and thereafter to harden, wherein the resin film is formed of a thermosetting resin; and when the resin film hardens by being heated, the resin film contracts and thereby acts to push the electronic component toward the mount substrate.
