Snyder International Ltd. Shenzhen Branch Newell Electronic Technology Co., Ltd. The company is a custom 2-40 layer PCB board professional supplier of rigid circuit boards, sheet main services provided are HDI boards, finger board, Bluetooth module board, half orifice, through plate, rigid-flex board, plywood sheets and a series of blind and buried vias PCB board: blind buried via pcb gold-plated mobile phone pcb pcb pcb double-sided copper clad PCB board Goldfinger: PCB board Goldfinger HASL PCB board: HASL pcb double-sided copper clad pcb gold plated PCB board: Industrial equipment finger pcb pcb pcb phone Other series pcb Immersion Gold PCB board in the face of double-sided documents PADS properties to choose vias property (Through ), can not generate drilling files can lead to leakage drilling. If you do metalized slots safest approach is to put together more than one pad, this approach is not necessarily wrong. The circuit layers Category: divided into single-sided, double-sided and multilayer boards. Newell Shenzhen Electronic Technology Co., Ltd., we often say GPS positioning module known as user part, it's like "Radio" received as a satellite broadcast demodulation C / A-code signal to a frequency of 1575.42MHz. GPS module does not broadcast signal, a passive positioning. By pseudo-distance operation and each satellite, determined using the intersection method from the receiver to draw longitude, latitude, altitude and time correction of these four parameters for complex circuit board manufacturers, it is characterized by multi-point fast fiberglass board circuit board, but the error is large. Initial positioning module requires at least four satellites involved in the calculation, called 3D positioning, three satellite positioning can be realized 2D, but poor accuracy. GPS module via the serial communication port constantly positioning information and auxiliary information output NMEA format for the recipient to select applications.
