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!
Do you know the role of installing the Goldfinger?
Through the golden finger and the card slot spring blade contact conduction, the external PCB and the main board are interconnected, and the user is convenient to remove and replace due to the difference of the user's performance needs.The most common goldfinger designs appear on graphics cards and memory bars inside a computer.
