5 Tips for Specifying PCB Hole Size Tolerance
One of the crucial yet often overlooked aspects of PCB design are the holes through which components are mounted. Specifying the tolerance of hole dimensions in PCB fabrication ensures proper fit of plated-through-hole (PTH) components. Just as important, those dimensions must be clearly communicated to the fabricator so that the boards are properly made. Now, Altium ® PCB design software allows you to add hole tolerance attributes for your pads
