2L PCB FAQ
Q: What the package of the products?
A: We use vacuum packaging.
Q: Do you accept PCB design with different boards on the same panel?
A: Of course, we can do different boards on the same panel.
Q: What kind of surface treatment process do you adopt on my double layer PCB boards?
A: Such as ENIG, Plating Gold, HAL-LF, Chem.Tin, Chem.Ag and OSP.But on you double-sided pcb usually uses immersion gold.
