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, quality assurance, reasonable prices. Bonded Copper PCB is obtained through the etching process. Bonded Copper and copper foil has a base plate, the base plate commonly used insulating material such as glass fiber and covered with a layer of copper foil (usually oxygen-free copper). After etching the copper foil remaining after a section of the twists and turns of copper circuit board recycling, these foils called traces. These trace function is equivalent to the circuit diagram of those connections, which are responsible for the pin components are connected together. Foil drilled with holes for mounting electronic components, called drilling. And for the component leads soldered copper is called pads. Newell Shenzhen Electronic Technology Co., Ltd., we often say GPS positioning module known as user part, it's like "Radio" received as a satellite broadcast demodulation C / A-code signal to a frequency of 1575.42MHz. GPS module does not broadcast signal, a passive positioning. By pseudo-distance circuit board schematic operation of each satellite, determined using the intersection method from the receiver to draw longitude, latitude, altitude and time correction of these four parameters Shenzhen circuit board, characterized by a point and fast, but the error Great. Initial positioning module requires at least four satellites involved in the calculation, called 3D positioning, three satellite positioning can be realized 2D, but poor accuracy. GPS module via the serial communication port constantly positioning information and auxiliary information output NMEA format for the recipient to select applications. Circuit board, Newell Year (online consultation), Shenzhen board is supplied by Shenzhen Electronic Technology Co., Ltd. Newell. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) Guangdong Shenzhen, printed circuit board leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Newell create leadership with the staff warmly welcome all inquiries negotiations to create Newell create a better future.
