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, circuit board materials, information, and reasonable prices. The late 1980s, with notebook computers, mobile phones, camcorders, represented by a small camera portable electronic products began to enter the market. These electronic products, fast moving small, lightweight, multi-functional direction, greatly promoted the PCB toward the fine pores, fine wire of progress. Under these PCB changes in market demand, enabling a new generation of high-density multilayer wiring - laminated plywood (called BUM) in the 1990s come out. This important breakthrough technology, but also so that the substrate material industry has entered a high-density interconnect (HDI) multilayer substrate materials led to the development of a new stage. In this new phase, the traditional technology by CCL new challenges. PCB substrate material both in the manufacture of materials, product varieties, the organizational structure of the substrate, the performance characteristics, or in the product's features, there is a new change, new creation. 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, Guangdong circuit board materials, the price is reasonable and drawing lines: lines are used as conduction between the original tool in the design will also devise a large copper surface as the ground and power planes. Line and drawing are made simultaneously. Screen Printing: This non-necessary structure, main function is labeled on the board the names of the parts of the Location box, easy assembly after maintenance and identify with. Hole: vias allow two or more lines each level conduction, larger vias are used as a plug-in parts, and another non-conductive hole is typically used as a surface mount positioning and fixing screws when assembling. PCB circuit board composition is not very simple, and all of them were particularly important for non-use of the PCB, its various components of the materials are not the same. Therefore, in general, the production of circuit board materials, PCB circuit board prior to production, circuit board materials company, we have to carry out PCB proofing, suitable for the production model, go according to PCB proofing circuit board for mass production . Flexible circuit board material | Guangdong circuit board materials | Newell record provided by the Department of Shenzhen-Electronic Technology Co., Ltd. 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!
