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, good or bad circuit board modules, and reasonable prices. General module has semi property, it is carried out the processing circuit board module surface technology on the basis of the chip, so that subsequent applications easier. For end users, the image of the point, said: Bluetooth module is a semi-finished circuit board module design specifications, Bluetooth adapter is finished, Shenzhen Electronic Technology Co., Ltd. - The Department of Bluetooth wireless technology is used in a spread spectrum digital narrowband signal coding technique, by encoding operation increases the number of bits sent, expanding the bandwidth usage. Bluetooth uses frequency hopping spread spectrum manner. Frequency hopping spread spectrum such that the power spectral density of the bandwidth of the signal is reduced, thus greatly improving the capability of the system of anti-electromagnetic interference, anti-crosstalk, making Bluetooth wireless data transmission more reliable. Circuit board module which, Shanghai City circuit board module, Newell Newell hit by the Shenzhen Electronic Technology Limited. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) strong, credible, a printed wiring board in Shenzhen, Guangdong and other industries has accumulated a large number of loyal customers.
