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, circuit board design software, the price is reasonable. Automatic detection technology circuit board with the introduction of surface mount technology and applied, and makes the packing density of the circuit board rapid increase. Therefore, even if the density is not high, the automatic detection of the general number of the board, the board is not only essential, but also the economy. In the complex circuit board testing, the Guangdong circuit boards, two common methods are tested and double needle bed or flying probe test. Snyder International Ltd. Shenzhen Branch Newell Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional supplier, circuit board design sample, sheet main services provided are HDI boards, finger board, a Bluetooth module board half-plate, through orifice, Flex PCB, plywood sheets and a series of line 1. Minimum width:. 4mil (0.1mm). That is less than 6mil width will not be produced, if conditions permit design, design bigger the better, the greater the width, the better the production plant, the higher yield generally conventional in design 10mil around this point is very important, design must be 2. Consider the smallest line: 4mil (0.1mm) .. Min.Trace.Spacing is line-to-line, line-to-pad distance of not less than 6mil from the production point of view, the bigger the better, the general routine in 10mil, of course under the design conditions, the bigger the better this is very important. 3. line to the contour line spacing 0.508mm (20mil) via through-hole 1. Minimum aperture:. 0.3mm (12mil) 2 smallest vias (VIA) pore size of not less than 0.3mm (12mil), Shenzhen circuit board test pads Single side no less than 6mil (0.153mm), preferably more than 8mil (0.2mm). 3. vias (VIA) to the hole spacing (hole edge to the hole side) is not less than 6mil, preferably greater than 8mil. 4. to outline pad pitch 0.508mm (20mil) circuit board _ Newell Year (online consultation) _ Guangdong board is supplied by Shenzhen Electronic Technology Co., Ltd. Newell. Newell Shenzhen Electronic Technology Co., Ltd.
