The integrating conversion technique employed by the APS-12D-1-02/TR8 effectively eliminates the effect of flicker from AC-powered lamps, increasing the stability of the measurement. Connected with an infrared LED (IRED), the built-in proximity sensor can reveal the closeness of approaching/departing objects. This device is intended primarily for use in applications in which measurement of ambient light and proximity sensing is a must, such as laptop computers, PDAs, camcorders, and GPS systems. Applications * * * * Detection of ambient light for controlling the backlighting of TFT LCD display Automatic residential and commercial lighting management Automatic contrast enhancement for electronic signboard Mobile phone, Notebook PC, Net PC, UMPC, GPS... etc. Everlight Electronics Co., Ltd.

Reflow soldering should not be done more than two times. 2. When soldering, do not put stress on the devices during heating. 3. After soldering, do not warp the circuit board. Soldering Iron Each terminal is to go to the tip of soldering iron temperature less than 350 for 3 seconds within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder. Repairing Repair should not be done after the device have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the device will or will not be damaged by repairing. Everlight Electronics Co., Ltd.
