1. Preparation includes preparation component library and schematic diagram

"If you want to be good, you must first benefit your instrument." To make a good board, in addition to designing the principle, you must also draw well. Before the PCB board design, you must first prepare the component library of the SCH and the component library of the PCB board. The component library can use the library that comes with Peotel, but in general, it is difficult to find the right one. It is best to make the component library according to the standard size data of the selected device. In principle, the component library of PCB proofing first, and then SCH component library.

PCB's component library requires high requirements, which directly affects the installation of the board; the component library of SCH is relatively loose. As long as you pay attention to define the corresponding relationship between the pipeline and the corresponding relationship with the PCB board component. PS: Pay attention to the hidden tube foot in the standard library. After that, the design of the schematic diagram is ready to start the PCB design after being done.

Second, the structural design of PCB manufacturers. Based on the size of the circuit board and various mechanical positioning of this step, PCB board surface is drawn in the PCB design environment, and the connecting parts, keys/switching, screw holes, assembly holes in the positioning requirements are placed according to the positioning requirements. And fully consider and determine the wiring area and non -wiring area (such as the non -wiring area around the screw hole).
