PCB Boards

Generally, basic PCB design process follows seven steps: pre-preparation- structural design- layout- optimization and silkscreen- net check, DRC check, and structural check- board fabrication. In this article, the first two steps will be outlined. 

Step 1: Pre-Preparation
A good board requires a good design and good painting skills. Before designing a PCB board, it is necessary to prepare a component library of the schematic diagram and the component library of the printed circuit board. You can use peotel library as the component library, however, generally it is difficult to find the right one, so you’d better make your own component library based on the standard size of your selected components.
In principle, you need to make the PCB component library first, and then make the SCH library. PCB component library requirements are higher as they can directly affect the board installation; SCH component library requirements are relatively loose as long as the pin attributes and the PCB components are corresponding. 
PS: Note the hidden pins in the standard library. After the schematic design is done, the PCB design is the next. 

Step 2: PCB Design
This step is to draw a PCB board surface based on the determined board size and the mechanical position, and put connectors, buttons/switches, screw holes, assembly holes, etc. according to the positioning requirements. Fully take the wiring and non-wiring areas into consideration, such as areas around screw holes are non-wiring part.
