1. Circuit and pattern (Pattern): The circuit is used as a tool for conducting between components. In the design, a large copper surface will be designed as a grounding and power supply layer. Lines and drawings are made at the same time. 2.Hole (Throughole/via): The through hole can make the lines of more than two levels conduct each other, the larger through hole is used as a component plug-in, and the non-conductive hole (nPTH) is usually used as the surface Mounting and positioning, used for fixing screws during assembly. 3.Silkscreen (Legend/Marking/Silkscreen): This is a non-essential component. Its main function is to mark the name and position box of each part on the circuit board, which is convenient for maintenance and identification after assembly.● -Layer Count: 2L/4L/6L/8L/10L ● -Max.
