Abstract
A method and apparatus for soldering terminal ends of an antenna embedded in a plastic smart card to contact terminals of an IC module disposed on the card are shown. The enamel coated antenna terminal ends are pre-coated with solder with a heater having horizontal opening with melted solder retained therein. The solder pre-coated terminal ends are maintained in a secured contact with the terminal contacts of the IC module by heating coils mounted at a free front end of two pivotal elongated cantilever arms. A piece of predetermined amount of solder is dropped into the cavity of each heating coil, and the heating coils are actuated with a low electrical current to generate a concentrated intense heat to melt the piece of solder to form secure permanent solder joints between the terminal ends of the antenna to the contact terminals of the IC module.
