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, reasonable prices. Many people have heard about 'PCB' the abbreviation name. But in the end What is the meaning of it? Actually very simple printed circuit board material prices, is a printed circuit board (Printed circuit board, PCB). It will appear in which almost every electronic device. If there is some kind of electronic components in the device, they are set in the sizes of the PCB. In addition to fixing a variety of small parts, the main function is to provide top of the PCB components are electrically connected to Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single panel, double-sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices dielectric layer: for holding the line and insulation between the layers, commonly known as the substrate. Solder Mask: not all have to eat tin on copper surface parts, so the non-food area of ??tin, copper surface isolation layer will be printed eat tin material (usually an epoxy resin) pcb circuit board material quality and avoid non-eating short-circuit between the tin. 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) silver circuit board material, it will be protected eat tin copper surface. Protection methods are sprayed tin, and gold circuit board materials, silver, tin, OSP, methods have advantages and disadvantages, collectively referred to as surface treatment.
