Hello, IPC-2223 contains an equation labeled 'Equation 2' for calculating the minimum bend radius for double-sided circuits with coverlay. I wonder if I am missing something because when I plug in the values shown there as an example the 'R' value does not match what is shown there. Any help would be appreciated.
