Does your order keep getting put on hold for insufficent inner layer clearances or your outer layer pads are too small and you're just not sure what this means?
Here is an inner layer clearance
Here is a outer layer pad
We have a drill table listed on our PCB Manufacturing page that shows what your pad size or clearance to your drill hole should be. Your pads should be .018" larger than the finished hole size for your outer layers and the inner layers we would like to see .025" clearance over the finished hole size (.020" for Full Feature).
