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. As electronic devices become more complex circuit board Bluetooth module, part needs more and more natural, PCB top of the line and part of more and more intensive. Bare board (top no parts) is also often referred to as 'the printed circuit board Printed Wiring Board (PWB)'. The base board itself is insulated, it is not easy to bend the material made into. Can be seen on the surface of fine copper wiring material, copper foil originally covering the entire board, and in the part of the manufacturing process is etched disposed, he left to become part of the mesh of the fine line . These lines are called conductors or said wiring and circuit components on the PCB to provide connectivity Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional supplier, mainly sheet provided there HDI boards, finger board, Bluetooth module board, half plate, through plate, rigid-flex board, plywood and other series of plates. Imposition whether the gap make-up, and there is a gap imposition phone circuit board module with a gap imposition Imposition gap not less than 1.6 (thickness 1.6) mm otherwise it will greatly increase the difficulty of milling job board imposition of large, overlooked the device is not the same is not the same circuit board module, about the imposition of 0.5mm gap gapless Process side no less than 5mm. A character width can not be less than 0.153mm (6mil) circuit board module discoloration, character height can not be less than 0.811mm (32mil), the ratio of height to width ratio is preferably 5 for the relationship to say, word width 0.2mm character height of 1mm.
