Snyder International Ltd. Shenzhen Branch Newell Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional providers. PCB printed circuit board historical Austrian inventor Paul Eisler (PaulEisler), he in 1936 in a radio device uses a printed circuit board. 1943 circuit board design, a large number of Americans use the technology in the military radio. In 1948, the United States officially recognized the invention is used for commercial purposes. Since the mid-1950s onwards, the printed circuit board technology began to be widely used. Shenzhen Electronic Technology Co., Ltd. Newell antenna condition monitoring how to do? Antenna open short circuit when the need how to handle it? The best way is to open the GPS antenna module can output short-circuit condition statement to prompt customers to do this inspection board, this advantage is that it allows customers to easily see the problems, while protecting the modules are not subject to large current impact, Many of these applications on the market board pictures, for example, S-87, S-90, S-93 and UBLOX some modules also has the function of a circuit board schematics, but the point is the difference between peripheral devices Ublox need to take to achieve this function, Vasco da Gama is without any peripheral devices, like flash version of this function can only be achieved, rom version can not be configured IO port, there is no way to achieve this functionality.
