Abstract

PURPOSE: A method for manufacturing an IC card by layering foils is provided to remove a step for digging out a groove again after layering the foils, firmly join the COB(Chip On Board) and a card plate, occur no gap between the COB and the card plate, and firmly join an electrode of the COB and an antenna. CONSTITUTION: The COB(200) is placed by facing an electrode surface of a terminal in the COB downwardly. At least more than two foils(300,400,500) having a hole(301) of the same area as the COB are layered by inserting the COB into the hole. A back side cover foil(600) having no hole is layered to an opposite side of the surface exposing the electrode surface of the terminal in the COB of the layered foils, and the foils are compressed.

Description

field of invention

[0001] The invention relates to an IC card manufacturing method. More specifically, the present invention relates to a method of manufacturing an IC card by laminating at least two foil sheets formed with holes corresponding to COB (Chip On Board) and bonding them to each other by pressure. Background technique

[0002] IC cards, which are cards carrying necessary data and programs in COB, are being used in more and more fields because of their convenience and good information retention capabilities. This kind of IC card can generally be divided into: through the contact between the card reader terminal and the electrode, the contact IC card that realizes the input and output of information, has an antenna inside, even if it is not in contact with the card reader terminal, A non-contact IC card capable of inputting and outputting information, and a combined IC card capable of realizing the functions of the above-mentioned contact and non-contact IC cards....
