The manufacturer to ensure the quality of cell phone jammer

The sampling inspection of  cell phone jammer has the specific requirement
Early in 1961 from Stanford University and 3M together to carry out the optical storage technology research, since we also had optical storage technology. In 1981, Philips and Sony jointly launched the CD player, and its wholly-called CD-DA. In 1993, Philips and JVC to develop a VCD standard. In 1992, the U.S. Agency for International Radio and Television Technology Exhibition, the C-CUBE display MPEG (image decompression) technology cause was Group General Manager of Anhui Jiangwan Meng interest, this technique can image stored in a small CD-ROM and sound. Since then, the Jiangwan Meng has invested $ 570,000.
Able to use their technology in China, their own ideas of the optical storage industry developed, and even lead the world. The laser head technology development status in 2001 Disc Industry Promotion Committee developed a DVD optical head standard in China, some of the relevant scientific research units have also invested a lot of manpower and resources to develop the DVD laser head technology with independent intellectual property rights, and has achieved remarkable results. The successful development of the domestic Tsinghua University, Optical Memory National Engineering Center DVD internal multi-dimensional moment, at the same time, a new DVD of the electronic switch of the TN liquid crystal cell, CD compatible optical head design program. The main features of this program is sufficient to ensure the quality of the read the DVD information. The safety lock of cell phone jammer  can ensure the safety and security of the customer.It should be obeyed by the manufacturer to ensure the quality of  cell phone jammer
At present, the laser head production is technically not only serious to rely on foreign manufacturers, and currently popular in the domestic market rather monotonous types, resulting in higher overall domestic prices, competition with foreign manufacturers has been at a disadvantage. But in China, many household electrical appliance enterprises are not far behind, and actively develop their own DVD products and DVD production core technology. Anhui countries share Optoelectronics Technology Co., Ltd. is a respected photoelectric core parts supply and service companies "for the mission," responsibility, focused, pragmatic, efficiency values based on the domestic market, to the Optical Memory National Engineering Center at Tsinghua University domestic cutting-edge technical support.
