8.4.2 covers the basic formula but the Land Pattern Creator does not calculate these for you. You need to know the dimensions in order to create a Land Pattern, if this were the case then couldn't I

. The Axial Lead math formula comes from IPC-2221 or IPC-2222. Axial Components Pitch Calculation : Thanks...Is there any theoretical

: IPC-2221B calculation formula is: Land size, minimum = Hole size + 2*Min. annular ring(Min 0.05mm) + fabrication allowance IPC-7351C calculation formula will be: Pad diameter = Hole size + 2*Min. annular ring(Min 0.2mm) , or = Hole size
