I recently ordered a PCB and on one component footprint I accidentally set the solder pad size to what should have been the hole size (diameter) for a thru-hole component.
The difference is about 0.5mm / 20mil. The component is a fuse holder with two pins per terminal which I will use with a 10amp fuse (so roughly 5amps will be carried by each pin):
In order to do some testing on this board while I wait for a re-order, I am wondering about a temporary fix. Here are my questions:
- Can I use a drill to increase the size of the holes?
- Do I need to do anything to the hole after increasing the size in order to ensure a good connection?
