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 board material prices, 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 immersion gold circuit board materials, larger vias are used as a plug-in parts, and another non-conductive hole is typically used as a surface-mount circuit board positioning material, is assembled by fixing screws. 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. So, in general, gold-plated circuit board materials, PCB circuit board prior to production, we have to carry out PCB proofing, suitable for the production model, go according to PCB proofing circuit board, high-volume production.

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. Usually we are talking multilayer core board and by stacking prepregs each other nip formed. And a so-called prepreg wetting layer, acts as an adhesive core board, although there are some initial thickness, but their thickness during pressing some changes will occur.
