A card reading device includes an insulating housing, at least a set of conductive terminals, a rear wall, and a shielding member. The rear wall includes a metal plate and a plastic plate that is formed by insert molding, which has a stable configuration and is unlikely to shake or distortion. The rear wall reliably presses and contacts with a top edge of a soldering portion of the conductive terminals, which is easier to be soldered so as to avoid soldering skipping or solder voiding. Moreover, the shielding member presses a top edge of the rear wall so as to make the rear wall securely press the soldering portion. Furthermore, the rear wall includes a plurality of openings therein, which make the gas circulate so as to avoid solder voiding. Thereby the qualified ration is improved. |
