Patent ID: 6841022

Claim:
A method of producing an adhesive-coated electronic part having an electrode surface coated with an adhesive layer, comprising: arranging a connection sheet including an adhesive layer and a separator from which the adhesive layer can be peeled, the connection sheet having a size greater than a size of an electrode surface of an electronic part on which electrodes are formed; bringing the electrode surface of the electronic part into contact with the adhesive layer of the connection sheet; heating the electrode surface to form a cohesion reduction seam in the adhesive layer across which cohesive strength of the adhesive lowers, the cohesion reduction seam being formed at a location between a region of the adhesive layer corresponding to the electrode surface and a region of the adhesive layer surrounding the electrode surface, said heating of the electrode surface comprising using a heating head located at a rear surface of the electronic part opposite the electrode surface; and separating the electronic part from the connection sheet such that part of the adhesive layer having a size substantially identical to a size of the electrode surface is separated from the separator and adheres to the electrode surface.
