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, professional supplier of PCB 2-40 layer multilayer principle, to provide high precision, high quality Shenzhen circuit board buried vias circuit board, quality assurance, reasonable prices. FR-4 substrate is a copper substrate highest level who is an epoxy resin, glass fiber cloth fabric was eight, and three distinct copper plating material impregnated, covered from pressure. Wherein the glass fiber cloth impregnated with epoxy resin adhesive film is formed as an insulating and supporting electronic components used between the copper foil is made for electronic components of the line connecting conductors. 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, research affordable domestic automatic detection system printed circuit board began around middle period of the 1990s, still in its infancy. Engaged in research in this area is relatively less research institutes, but also because of the influence of various factors, research for the printed circuit board defect AOI system is also stuck in a relatively early level. Because automatic detection system overseas printed circuit board is too expensive mobile phone circuit board, but there is no developed country in the true sense of the printed circuit board automatic test equipment, so the vast majority of the domestic circuit board manufacturer or artificial with a magnifying glass or Projector side view of approach to the subject. Due to the large labor-intensive manual inspection, eye fatigue, high leak rate test. Moreover, with electronic products towards miniaturization, digital development, printed circuit boards also moving high-density, high-precision development, test methods using artificial board, basically impossible. For higher density and precision circuit board (0.12 ~ 0.10mm), have been completely unable to test. Detection means backward, led to the current domestic multilayer (8-12 layers) of the product passing rate of 50 to 60%. Circuit board design, circuit board in Shenzhen, Newell record (view) from the Department of Shenzhen-Electronic Technology Limited. Newell Shenzhen Electronic Technology Co., Ltd.
