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, the impedance of the circuit board, for clients provide high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. In this part of CCL, circuit board design issues, there may be B-class board there are three, one is a glass cloth defects in materials, and the second is a problem prepreg or out of date, and the third is a pinhole and copper oxide, and in the CCL manufacturing process will produce B-level board may, a process is a glass cloth impregnated with epoxy resin at the time, the board cross-line principle, not all impregnated, bubbles exist. The second is in Overlaid CCL is Shenzhen board, pressure with the temperature right, resulting in gum or rubber, which also generates a B-level board. Above that is the core material of PCB CCL produces a B-level board, and a lot of PCB manufacturing process, will also have a lot of B board Shenzhen Electronic Technology Co., Ltd. Newell GPS module in practical applications often used as a time reference , supplemented inside the module RTC, get very high-precision time reference for the product is designed to provide a great convenience. As for the GPS speed, but on the basis of obtaining the latitude and longitude, make an extension application to achieve simple calculation.
