Method Of Manufacturing A Smart Card

Abstract

A method of manufacturing a smart card (20) embedded with an integrated circuit module (28) and an antenna coil (8) includes step (a), embedding an antenna coil (8) on a core sheet (6), (b), laminating the core sheet (6) with a number of outer sheets (10, 12, 14, 16) to form a laminated panel (18), (c), forming a cavity (22) in the laminated panel (18) to expose two ends (24) of the antenna coil (8), and (d), connecting two electric contact regions (30) of an integrated circuit module (28). The exposed ends (24) of the antenna coil (8) are connected by a mezzanine electrode diffusion welding method, controlled by a transformer output manipulation energy output control method.
