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 storey density multilayer professional supplier, to provide customers with high-precision high quality Shenzhen board, quality assurance, reasonable prices. For low frequency analog circuits, in addition to bold and shorten the ground, each part of the circuit is the best choice for one-point grounding ground interference suppression, flexible circuit board materials, mainly due to the ground to prevent common impedance between the resulting parts The mutual interference. As for the high-frequency circuits and digital circuits, since then the ground inductance Effect will be even greater, circuit board materials suppliers, a little longer grounded cause actual adverse impact ground, then the ground should be taken apart and a little Ground combination Snyder International Limited Shenzhen Branch Newell Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 storey density multilayer professional supplier, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. We can not just pass electrical insulation board, an integrated circuit board materials, so the surface needs copper. So we put the PCB, also known as copper substrates. In the factory, the code is common copper substrate FR-4, this is generally no difference in the various card manufacturers inside, so we can say that we are at the same starting line, Guangdong circuit board material, of course, if the high-frequency board card, preferably with the high cost of copper-clad glass cloth PTFE laminate.
