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. General FR-4 and high Tg difference of FR-4: Yes in the hot state, especially in the absorbent material when heated aluminum plate under the circuit board, the mechanical strength of the material, dimensional stability, adhesion, water absorption , differences in the thermal decomposition of a variety of conditions, thermal expansion, etc., high Tg significantly better than conventional products PCB substrate material. 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 circuit board circuit board material details of the deal, quality assurance, reasonable prices. A lot of people can not tell the difference between analog and signal ground, and sometimes do not distinguish between digital and analog, but that would make the circuit board material degradation, affecting the performance of the circuit: analog circuits involving weak signal, but digital circuit threshold level is high, the power requirements on some lower than analog circuits. Systems have both digital circuit analog circuit in the circuit board layers of material, the noise will affect analog digital circuits, and the analog circuit small-signal indicators deteriorated way to overcome is to separate analog and digital circuit board material details of the deal, Newell invasive, Shenzhen circuit board material by the Department of Shenzhen-Electronic Technology Limited.
