PCB with plating gold surface
1. solderability: plating gold solderability is equal to OSP pcb, while ENIG PCB is equal to HAL PCB, HAL solderability is the best among all surface finishing of PCB.
2 Gold Thickness, plating gold surface thickness is much thicker than ENIG PCB, but pad flatness is not as good as ENIG finishing.
3. Plating gold is normally suit for gold finger, some times also plating gold to solder pad.
