Claim 11:
12. A wireless communication card manufactured in a method comprising the steps of:
processing an antenna inlay layer including an antenna coil;
stacking a first overlay layer that covers a top surface of the antenna inlay layer;
processing a PVC insert inserted in a chip-on-board (COB) accommodation space, which is formed by milling a specific area of the first overlay layer, and provided with an accommodation groove in which a lower portion of a pad of the COB is supported;
passing both ends of the antenna coil drawn out from the antenna inlay layer through the PVC insert, and connecting the antenna coil to contact areas of the COB; and
mounting the COB in the PVC insert inserted in the COB accommodation space, wherein
the step of processing a PVC insert includes, the step of extracting the PVC insert having an area the same as that of the COB from a laminate material by laminating a COB scrap, wherein the COB scrap is obtained by winding a surplus sub-body that remains after a plurality of arrayed COBs is punched and opened by perforation in order to obtain the COB, and a PVC film wound around a second reel, and by perforating the laminated laminate material in an area the same as that of the punched opening.
