Printed Circuit Design Tutorial (K. Half hole design)

K. Half hole design

Half PTH holes are usually designed at the edge of the board, the holes are plated. The way to design this is just to put the  holes at the edge of the board, and put the border line across the middleof the holes. The min hole size will need to be 0.8mm (32mil), the min clearance between the holes need to be 1.1mm from the center from one hole to another. There  is no requirements for thesize of the pads, you can design the pads the same size as the hole.
