The name of the board are: PCB, PCB board, circuit board materials, aluminum plate, high-frequency boards, thick copper, impedance board, PCB, thin circuit boards, thin boards, printing (copper etching techniques) Board Wait. The circuit board mini, visualization, and optimization of fixed circuits for mass production with the electrical layout plays an important role. Circuit board may be referred to a printed circuit board or a printed circuit board, the English name (Printed Circuit Board) PCB. 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 storey density multilayer professional supplier, to provide customers with high-precision high quality Shenzhen board, quality assurance, reasonable prices. For high-frequency circuit also consider how to suppress high frequency radiated noise, it is: be bold ground, in order to reduce the noise on the impedance; over the ground, that is in addition to traces of the transmission signal, the other part of the whole as a ground. Do not Have a large area of ??copper foil used. Ground should form a loop, to prevent high-frequency radiation noise, but surrounded by the loop area is not too large, so the instrument is in a strong magnetic field, the induced current. However, if only the low-frequency circuit, board schematics, avoid ground loops. The best of digital and analog power isolation, separated from ground arrangement, if there is A / D, where only a single point in common to the circuit board proofing, Shenzhen board, Newell record (view) from the Department of Shenzhen-Year Electronics Technology Limited. 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.
