Circuit design techniques, PCB design flow
Second: PCB (HDI pcb Printed circuit board) structure design. This step, according to the size of the circuit board and mechanical positioning, PCB design environment to draw PCB board surface, and according to positioning requirements placed the required connector, key / switch, screw hole, assembly hole, and so on. And fully consider and determine the wiring area and non wiring area (such as the screw hole around the large area belongs to the non wiring area).
Third: PCB (Small volume pcb manufacturer) layout. Layout is plain, put the device on the board. At this point, if all of the preparatory work discussed earlier is done, the network table (Design->CreateNetlist) can be generated on the schematic diagram, and then the network table (Design->LoadNets) will be imported on the PCB diagram. Saw the device crashed all over the heap, and there are links between the legs of the cable line prompt.
