Golden finger function: ① If Shen Jin+Gold -plating finger process is made, the welding of double -sided PCB boards will be very good, the performance of the PCB board will be stable, the pads will be stronger There will be poor contact and short circuit. ② If you choose to spray tin+gold -plated finger (PCB board with golden fingers, other plate surfaces are tin spray), you need to be able to double -sided PCB board width and pads.③Reducing the cost of production, and it will not affect the use of PCB double panels.
