Desktop computers boot failure detection and maintenance

In Electronic Infomation Category: D | on October 28,2011

(more DIY computer repair and MC3362DW datasheet and other knowledge, see-dimensional database technology information network ) on the desktop can not boot / no display failure, many of my friends feel that unable to start, could only turn to the business process. In fact, as long as there is a plum screwdriver, you can easily determine whether a computer failure, thus saving the telephone...

LED light reflection rate increase

In Electronic Infomation Category: L | on October 28,2011

As shown in Figure 2-25, in order to improve external quantum efficiency (hereinafter known as the light extraction efficiency), in addition to the metal reflective layer, the electrode structure also made modest improvements. Reflector with a light-emitting layer can generate the direction of reflected light toward the substrate, so that light from the LED surface removed. Reflective layer is loc...
