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 plywood supplier silver professional circuit board material for clients provide high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices dielectric layer: for holding the line and insulation between the layers, known as the substrate. Solder Mask: not all have to eat tin on copper surface parts, so the non-food area gilt tin circuit board material, will be printed eat tin copper surface layer of isolation material (usually an epoxy resin), to avoid non-eating tin between short-circuit. Depending on the process, into green oil, oil, oil blue. Surface treatment: since copper surface in the general environment, it is easily oxidized, resulting in not on the tin (solder adverse), and therefore be protected eat tin copper surface. Protection methods are sprayed tin, gold, silver, tin, OSP, methods have advantages and disadvantages, collectively referred to as surface treatment. 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, the price is reasonable PCB circuit board is a printed circuit board or printed circuit boards, insulating panels to the substrate, cut to size, with at least one on which the conductive pattern, and a cloth with a hole What is a circuit board material, used in place of conventional means of electronic chassis components, and to achieve interconnection between electronic components. PCB circuit board used in a very wide range of computer motherboards, IC board, all with the PCB-related products. It runs through our lives, and all walks of life work. PCB circuit board Why such a wide range of purposes? It is composed by what part? In fact, the PCB is mainly composed of several parts of the dielectric layer, the resist ink, surface treatment, line and drawing, screen printing, holes and other components. What is a circuit board materials, Shenzhen circuit board materials, Newell record (view) provided by the Department of Shenzhen-Electronic Technology Co., Ltd.
