Detailed Description
Referring to fig. 1 and 2, the smart card with standing gold 11 provided in this embodiment includes a metal sheet layer 1, a shielding layer 2, an intermediate layer 3, a back surface printing layer 4, and a back surface covering film layer 5, which are laminated in this order. The shielding layer 2 and the middle layer 3 are bonded through a first colloid layer 6, the middle layer 3 and the back printing layer 4 are bonded through a second colloid layer 7, and the metal sheet layer 1 and the shielding layer 2 are bonded through a third colloid layer 8. The intermediate layer 3 is provided therein with a communication coil (not shown in the drawing) and an RFID chip (not shown in the drawing) electrically connected to each other, and the shielding layer 2 is a ferrite layer or the like. The holding groove 9 has been seted up to the one side of sheetmetal layer 1 facing away from intermediate level 3, and holding groove 9 is logical groove, inlays in the holding groove 9 and has found golden 11, and the upper surface of found golden 11 exposes in sheetmetal layer 1, and the shape of found golden 11 is the same with holding groove 9, and found golden 11 and the upper surface of shielding layer 2 pass through adhesive 10 bonding.
Alternatively, the accommodating groove 9 is a blind groove, and the standing gold 11 is adhered to the bottom wall of the accommodating groove 9 through an adhesive 10.
The accommodating groove 9 comprises an upper portion 90 close to the upper surface of the metal sheet layer 1 and a lower portion 91 close to the shielding layer 2, the cross-sectional area of one side of the lower portion 91 close to the shielding layer 2 is larger than that of the lower portion 91 close to the upper portion 90 on the projection of the plane where the metal sheet layer 1 is located, the lower portion 91 is in a horn shape, the cross-sectional area of the lower portion 91 gradually increases from the direction close to the upper portion 90 to the direction close to the shielding layer 2, the thickness of the lower portion 91 is between 0.02mm and 0.04mm, the thickness of the metal sheet layer 1 is between 0.3mm and 0.6mm, and the depth of the accommodating groove 9 is between 0.05mm and 0.5 mm.
