Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high Shenzhen circuit board quality, Guangdong circuit board module, quality assurance, reasonable prices. Automatic detection technology circuit board with the introduction of surface mount technology and applied, and makes the packing density of the circuit board rapid increase. Therefore, even if the density is not high, the automatic detection of the general number of the board, the board is not only essential, but also the economy. In the complex circuit board test, two common methods are tested and double needle bed or flying probe test. Shenzhen Electronic Technology Co., Ltd. Newell GPS module cold start, warm start warm start (today's technology basically has the cold start and warm restart mode parameter has done two very close, so it phased out warm start) three parameters, if GPS module is powered for the first time, four circuit board module, or move more than 500 km after power, the multi-layer circuit board module, the module to be recalculated once ephemeris data, GPS module under normal circumstances only 30 Multi seconds to normal positioning (which is a cold start), S-87 has a built-in button batteries, can be inside the module, when the next module can be quickly locate ephemeris data storage, usually as the S-87 只takes 1 to 3 seconds can achieve a new positioning, a circuit board module design principle, that this positioning is called hot start, if the module off time more than four hours, there is no real-time power supply internal RTC, then again turn is also equivalent to Cold start. Circuit board module foil thickness, Guangdong circuit board modules, Newell record (view) provided by the Department of Shenzhen-Electronic Technology Co., Ltd. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) is a professional "pcb board" company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "division Snyder, Newell a" brand has a good reputation. We adhere to the "service first, customer first" principle, so that record Newell won the trust of customers all of the printed circuit board, and establish a good corporate image.
