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. Circuit schematic design is the use of Protel DXP Schematic Editor to draw schematics. Network Reports Network Report is generated circuit diagram show a link between the various components of the report and the multilayer circuit board material, which is connected to the circuit schematic design and board design (PCB design) bridge and link, via the circuit schematic Network report, you can quickly find contact circuit board materials testing between components, thus facilitating Snyder International Limited Shenzhen Branch Newell Electronic Technology Co., Ltd. - The Department of Electronic Technology company was behind the design is a professional PCB custom single-sided, double-sided, 2-40 layer multilayer professional providers, to provide customers with high-precision, high-quality Shenzhen circuit board circuit board materials, quality assurance, reasonable prices. PCB exposed hole plating mask forming process, involving the circuit board vias hole wall, welding position, the circuit board is partially coated or plated with thick lines in different metal layers associated processes; comprising the steps of: (1) Select the vias CCL has metalized blocks or boards; (2) an ink or paste printing photographic photosensitive dry film, and photographic ink drying; (3) has drawn a good light vias holes or welding position or line part Local film to be thickened, counterpoint exposure; (4) developing the exposed after the exposed light solid vias holes or welding position or line part of the partial vacancy needed to be thickened or welding position; (5) mask-hole plating electronic circuit board material to a desired thickness; (6) In addition to the surface cover of ink or photosensitive dry film was vias holes or welding position or line to be part of the local thickening of CCL block or circuit board. The process is simple, can be a great saving of copper, other metals and chemicals, less environmental pollution.
