Shenzhen Electronic Technology Co., Ltd. Newell GPS module performance * price index mainly receiver sensitivity, positioning time, position accuracy, power consumption, time accuracy. Module power positioning time is very different in different startup mode. In general, the cold start time refers to the internal modules have not saved any help to locate the data, including the ephemeris, time, etc., usually in less than 1 minute nominal; Warm start time refers to the internal module newer satellite ephemeris (generally not more than two hours), but the time difference is large, generally less than 45 seconds nominal; hot start time is the shutdown was not more than twenty minutes, and RTC time error is very small case. Usually less than 10 seconds nominal; recapturing time as auto drilled a tunnel circuit board, recapturing satellites out of the tunnel. Usually the nominal within 4 seconds. 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 which board for customers provide high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. Production of copper foil if requirements are relatively high, so in the production process. The possibility of the problem is not large, but there are two more serious problem of copper foil, a pinhole (pores), a surface oxidation, due to the production of copper CCL are based on the form of copper plating circuit board benefit, so if bath impure, then it would cause a pinhole, and copper production after a good multi-layer circuit board, if improperly stored, it will oxidation. With such a foil produced CCL, of course, a grade B board. Glass cloth impregnated with epoxy resin after a rapid warming, followed by rapid cooling of the glass cloth and epoxy resin combined into a cured state, known as prepreg. But the cured state is very unstable, and therefore must be placed in 20 ° about the problem, save, and the shelf life is very short. If you take that expired prepreg to pressure CCL, then out of the course grade B board circuit board power planes | Newell record (certified) | Chengdu circuit board provided by the Department of Shenzhen-Electronic Technology Co., Ltd. Newell Shenzhen Electronic Technology Co., Ltd. (www.yipcb.com) (www.yipcb.com) Guangdong Shenzhen, printed circuit board leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Newell create leadership with the staff warmly welcome all inquiries negotiations to create Newell create a better future.
