Snyder International Ltd. Shenzhen Branch Newell Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional supplier of production module circuit board how long it takes, there is the main provider of sheet HDI boards, finger board, Bluetooth module plates, half plate, through the plate, rigid-flex board, plywood and other series of plates. Printed circuit board design is based on circuit schematics, circuit designers to realize the function required. Printed circuit board layout design mainly refers to the need to consider a variety of factors external connector layout, optimizing the layout of the internal electronic components, optimizing the layout of metal wires and vias, electromagnetic protection, thermal dissipation. Excellent layout can reduce production costs, achieve good circuit performance and heat dissipation. Simple layout can be realized by hand, complex layout needs the computer-aided design (CAD) implementation. Newell Shenzhen Electronic Technology Co., Ltd., we often say GPS positioning module called user part of the circuit board, it's like "Radio" receive the same satellite broadcast demodulation C / A code signal circuit board gold thin have any questions, to a frequency of 1575.42MHz. GPS module does not broadcast signal, a passive position. By pseudo-distance operation with each satellite receiver using the distance calculated intersection method derived latitude, longitude, altitude and time correction amount of these four parameters, is characterized by fast point, but the error is large. Initial positioning module requires at least four satellites involved in the calculation, called 3D positioning how to identify the thickness of gold-plated circuit boards, three 2D satellite positioning can be achieved, but poor accuracy. GPS module via serial communication port continuous positioning information and auxiliary information output NMEA format for the recipient to select applications. Why board needs proofing, Newell record (certified), Shaanxi Province, Shenzhen board by Newell Electronic Technology Limited. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) Guangdong Shenzhen, PCB's leaders over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Newell record in leadership with the staff warmly welcome all inquiries negotiations to create Newell create a better future.
