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 quality Shenzhen circuit board buried vias board fiberglass board, quality assurance buried vias board expansion, at reasonable prices. As a result of the non-through vias technology, making large vias on the PCB will be very limited, it is possible to provide more space for traces. The remaining space can be used as a large area of ??the shielding purposes to improve EMI / RFI performance. At the same time more space can also be used for devices and key inner partially shielded cable to have optimum electrical performance. Non-wearing pilot hole, it can more easily pin fanout devices, making high-density pin devices (such as BGA packaged devices) it is easy to wiring and shorten the length of the connection, to meet the high-speed circuit timing requirements. 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 circuit board professional supplier, to provide customers with high-precision high quality Shenzhen board, quality assurance, reasonable prices. Blind hole in which only the top or bottom layer visible, the other can not see that layer, that blind holes are drilled from the surface, but do not drill through all the layers. Blind holes may be as long from 1-2 or from 4-3 (benefits: 1 buried vias board special resin, 2 conduction does not affect the alignment of 3,4); and vias throughout 1,2,3 , 4-layer circuit board buried vias for layer alignment influential irrelevant, but the higher cost of blind holes, need laser drilling machine. Blind plate is applied and one or more communication with the inner surface layer, the hole in the side is the side of the board, and then through to the interior of the board of date; simply put, it is a blind hole surface can only see one side, the other side in the plate yard. Generally used in four or more than four PCB board substrate buried blind hole circuit board _ Gansu province buried vias board _ Newell record provided by Shenzhen-Electronic Technology Co., Ltd. Department. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) strong, credible, a printed wiring board in Shenzhen, Guangdong and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Newell invasive and you hand into the brilliant, for a better future!
