The company holds a great hope on the domestic sales of Cell Phone Jammers .
With the continuous development of electronic technology, the complexity of the electronic components are increasing, so the components of the substrate processing more and more difficulty, for example, to the ceramic substrate complex contour machining and drilling, with the conventional method is difficult to ensure dimensional accuracy requirements, with high beam quality pulsed YAG laser processing of 2mm thick ceramic substrate, accuracy up to ± 0.05mm. Printed circuit boards using laser processing has also been widely used, especially in highly integrated surface mount device pin count, more and more smaller and smaller space, making prototype printed circuit boards not only duration, but also expensive, with YAG laser can process outlet width and spacing of 40μm of the printed circuit board. As early as 1976, began using this technology abroad, at least thousands of printed circuit boards installed in the laser processing system. Laser engraving and marking a mask imaging in two ways: cover mode marking laser imaging to the template pattern and ablation of the surface markers, laser source is mainly used CO 2 lasers. Sculpture-marking is a full-function high-speed marking system, laser beam Jing-dimensional optical scanning mirror focus after reflection to the surface, under computer control to set the trajectory of the material by vaporization, standard carve graphics or text, laser source is mainly used YAG laser.  China's laser processing of applications with different foreign countries, for the purposes of comparison, the 1998 application are listed in Table 4: China's 1998 total sales from 160 million yuan of view, with foreign sales in 1998 amounted $ 2.59 billion ( about 21 billion yuan) compared to explain China's major industrial areas of laser processing systems for technological transformation of traditional industries have a large space. Do not use advanced laser manufacturing systems will be difficult to deal with China to bring foreign products to enter the WTO on the Chinese market impact, while the market development fully demonstrates China's laser processing system has a large space. Do not use advanced laser manufacturing systems will be difficult to deal with China to bring foreign products to enter the WTO on the Chinese market impact, while the market development fully demonstrates China's laser processing system has considerable room for development, great importance should be given to the industry. The customer is satisfactory with the result of the final acceptance of Cell Phone Jammers .  In the laser welding process, when the laser beam hit the metal material, the heat transfer by thermal conduction to the surface and deeper below the surface. The role of the laser heat source, the material melting, evaporation, and the thickness direction of the workpiece through the formation of long and narrow hollow, with the laser welding carried out holes along the seams between two moving parts, thus the formation of the weld. Salient features of laser welding is a big melting, bead, small heat-affected zone, and high power density. Laser welding represents a small area in between the heating and cooling fine balance. The purpose of laser welding is produced by radiation absorption liquid bath, and make it grow to the ideal size, and then move along the solid interface, eliminating the welded components of the initial gap between the formation of high-quality welds. Pool is too large, too small, or the evaporation of a serious, will lead to weld failure. The lecturer always choose to use Cell Phone Jammers for convenience.
