We use pattern classes and drill classes as convenient shorthand method to measure the manufacturability of the PCB.

This controls whether the board can be made in our pooling services (PCB proto, STANDARD pool, TECH pool, IMS pool) and controls the price.

This classification is also used as a basis in our design rules made available for certain CAD programs ( currently for Cadsoft Eagle ).

For more information please see our PCB Design Guidelines – Classification page.
