  • Patent number: 8642899
    Abstract: A method for manufacturing an electronic device comprising a terminal provided with a conductor which penetrates a cured prepreg is provided. At least one opening is formed in the prepreg. The prepreg is attached to a substrate over which an electronic element is formed so that the conductor included in the terminal overlaps with the opening. A conductive paste is provided in a region of the prepreg where the opening is provided. Part of the conductive paste flows into the opening to be in contact with the conductor included in the terminal. Then, heat treatment is performed so that the conductive paste and the prepreg are cured. In the process for manufacturing the terminal, it is not necessary to perform a step of forming an opening with a laser beam after the prepreg is cured. Thus, an adverse effect of a laser beam on the electronic element can be eliminated.

  • Patent number: 8345435
    Abstract: A conductor having a projecting portion is formed which forms a terminal portion. An uncured prepreg including a reinforcing material is closely attached to the conductor and the prepreg is cured to form an insulating film including the reinforcing material. When the prepreg is closely attached, the prepreg is stretched by the projecting portion, so that a region of the prepreg, which is closely attached to the conductor, can be thinner than the other region of the prepreg. Then, by reducing the thickness of the entire insulating film, an opening can be formed in the portion having a smaller thickness. The step of reducing the thickness can be performed by etching. Further, it is preferable not to remove the reinforcing material in this step. The strength of a terminal and an electronic device can be increased by leaving the reinforcing material at the opening.

  • Patent number: 8240030
    Abstract: To provide a method for forming an opening with high accuracy in an insulating film obtained by curing a prepreg including a reinforcing material in a step of exposing a terminal portion sealed with the insulating film, with the use of a means other than laser beam irradiation. A protrusion is formed using a conductor. An uncured prepreg including a reinforcing material is closely attached to the protrusion and the prepreg is cured, so that an insulating film including the reinforcing material is formed. A portion of a top surface of the insulating film protrudes due to the protrusion. The protruding portion is preferentially removed together with the reinforcing material to form an opening in the insulating film by grinding treatment or the like, so that an opening which exposes the protrusion is formed in the insulating film.
