. IPC uses the Pad Size to calculate Thermal Relief and Proportional uses the Anti-pad to calculate the Thermal Relief. The big difference is that the Anti-pad is a much more stable number because it's calculated by the hole size which is always consistent

Posted: 08 Nov 2012 at 12:03pm I just generated a 4x2 shrouded header and I have questions regarding the output. 1) The hole size is shown as 1.08mm (based on .62mm square pin

;There is also a Toolbox with a Pad Stack Calculator. You can either enter the terminal lead length width or the hole size length and width and it will calculate all the pad stack details.
