The Premium PCB Service can meet more than 95% customer’s requirements, for some guys, especially makers/startups who have experience in hardware developing and electronics projects that need many special requirements, they will need more reliable & advanced PCB services, such as multiple layers more than 4, FPC (for example: FPC With stiffener, Rigid-Flex PCB, Multilayer FPC), Immersion silver(AG) finished, Flash gold/gold finger, Epoxy Via Plug, BGA or pad less than 0.3mm, a width of wire less than 4 mils, drill holes less than 0.3mm, insulated Metal Substrate, HDI, High-frequency Rogers, Castellation Plating, etc... That’s why Makerfabs provides this "Premium PCB Service".

2. What’s the main upgrade compared to the common PCB services?

This “Premium PCB” service is based on “One-by-One Quotation”, so we will be able to meet your personal requirements. Compared to the common PCB service, the main upgrade is:
