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. Clock oscillation circuit board layout, special high-speed logic circuit winding up part of the land, so close to zero around the field. I / O-driven devices, power amplifier element as close as possible PCB, near lead connectors. The system can meet the requirements of the lowest frequency of the clock, the clock generator as close as possible to the clock of the device used. Quartz oscillator housing to ground, the clock line as short as possible, and do not attracted everywhere. Use 45-degree fold line wiring, do not use the 90 degree line, in order to reduce the transmission of high frequency signals.
