We have created an EAGLE DRU file for each of all of our Eurocircuits PCB pooling services (PCB proto, STANDARD pool, TECH pool and IMS pool).
Unless in case of any unexpected anomaly, using these DRU files and their values will assure that your PCB design will fit in the pooling service linked to the DRU of your choice.
