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.

摘要:
A high-efficiency multiple-pass nonlinear wavelength converter and amplitude modulator employs a variable dispersion element between adjacent passes of a nonlinear wavelength conversion process in a single nonlinear optical material substrate. When controlled by a voltage via the electro-optic effect, the variable dispersion element dynamically alters the phase matching condition of the multiple-pass nonlinear wavelength conversion process and thus modulates the laser output amplitude. When the phase mismatch between passes is completely compensated by the variable dispersion element, the multiple-pass nonlinear wavelength converter achieves its maximum efficiency.
