Pad Diameter for Components on a PCB WA2FTV on 30/7/19
Cedric,

There's plenty online regarding plated through hole size and NPTH - a guide is here:

http://www.pcb-3d.com/tutorials/how-to-calculate-pth-hole-and-pad-diameter-sizes-according-to-ipc-7251-ipc-2222-and-ipc-2221-standards/

There's also charts:

Some in that page.

73's,
