Abstract
VFD need to have a number of factory testing to include: high-pressure testing, a single scan, multiple scans, scan grid, allLight scanning. Detection system to the traditional detection through two machines, one to disassembly after testing to another instrumentDetection of the remaining, the process cumbersome, prone to error. The main purpose of the system is to use as a controller Panasonic FPX two-yee Save a device combining the middle of the process of disassembly, thereby enhancing work efficiency and also reduce the error rate, reduced workersWork intensity.
The vacuum fluorescence display monitor (VFD) using electronic impact phosphor, so that light-emitting phosphor is a self-luminous display.Because it can do more than color display, high brightness. Conductive thin-film substrate requirements VFD line width and line spacing less than 0.03mm, Resulting product is therefore vulnerable to connect with the disconnected, as the products of these two causes accounted for the end-of-life products for more than 80% of non-performing.
