Line width 0.22 mmPCB board with gold fingers

General pcb wiring line width considers two problems.One is the size of the current, if the current is large, the line can not be too thin; the second is to consider the actual board manufacturing capacity if the current is small, the line can be fine, but too fine, some PCB board factory may not make, or produced but the yield rises, so China Best Technology Co., Ltd. is your best choice!
