MANUFACTURING METHOD OF UIM WITH CARD FRAME, AND UIM WITH THE CARD FRAME

摘要

PPROBLEM TO BE SOLVED: To provide a manufacturing method of a user identity module (UIM) with a card frame, and a UIM with a card frame, which does not scratch a person, without leaving sharp protrusions on frame sides, when the UIM 1 is broken off from the card frame 2. PSOLUTION: The UIM with a card frame has a surrounding slit within the card frame for forming the UIM 1 enclosed therein, and bridges 1 and 3 through which the UIM is connected to the card frame. The manufacturing method of the UIM includes the steps of (1) milling the surrounding slit 4 by an end mill, with the bridges 3 being left on the periphery of the UIM on the card frame, (2) machining half-cuts 6 at the bridge portions along the periphery of the UIM, and (3) forming a notch 5, by the end mill on the periphery of the UIM and at both ends or both of near ends of the bridge portions so that sharp protrusions are not left on the card frame sides, after breaking off the UIM.
