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 circuit board professional supplier of special features, providing customers high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. A method for the printed circuit board prototyping is to use a low viscosity inks specially designed for high tack, highly conductive film formed in each through-hole wall. This eliminates the need to use a plurality of chemical processes, only one application step, followed by thermal curing, a continuous coating film can be formed in all the special circuit boards inside of the cell walls, it does not need further treatment may be directly electroplated.
