PCB design problems

<< < (3/3)

For Pad size calculation use this formula.
Minimum Pad size, P = (2 x R) + FA + D
P = Pad size, R = Annular ring, FA = Fabrication allowance, D = Drill or tool diameter

For hobby level PCB design, add 1 to 2 mm to drill size to get the Pad size. 

I know this is probably stupid but would it be possible to use a conductive pen for spot repairs?
