Snyder International Ltd. Shenzhen Branch Newell Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional providers, the main provider of the plate there HDI boards, finger board, Bluetooth module board, half plate, through the plate, rigid-flex board, plywood and other series of plates. Plug the hole depending on the size of your components to be, but it must be greater than your components pin 0.2mm above proposal is greater than the minimum of 0.6 means that components of the pin, you have to be designed at least 0.8 thick copper circuit boards to Anti-machining tolerances cause difficulty inserted. Snyder International Ltd. Shenzhen Branch Newell Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional providers, the main provider of the plate there HDI boards, finger board, Bluetooth module board, half plate, through the plate, rigid-flex board, plywood and other sheet metal series line 1. Minimum width:. 4mil (0.1mm). This means that if the line width of less than 6mil will not produce, if conditions permit, design, design bigger the better, the greater the width, the better the production plant, the higher yield of around 10mil conventional general design of this very important steel board the design must consider 2. Minimum line distance: 4mil (0.1mm) .. Minimum line spacing is the line-to-line, line-to-pad distance of not less than 6mil departure from power circuit board production point of view, the bigger the better board, general routine at 10mil, of course, the design of conditions, the bigger the better This point is very important. 3. Line to outline pitch 0.508mm (20mil) via vias 1. Minimum aperture:. 0.3mm (12mil) 2 minimum vias (VIA) aperture of not less than 0.3mm (12mil), the pad can not be less than unilateral 6mil ( 0.153mm), preferably greater than 8mil (0.2mm). 3. vias (VIA) to the hole spacing (Hole to Hole) can not be less than 6mil, preferably greater than 8mil. 4. pads to outline pitch 0.508mm (20mil) steel board | Newell record (certified) | Changshou District board provided by the Shenzhen Electronic Technology Co., Ltd.
