Bill,

I get the same results as shown.

R = (100/2 + 35) * [(100-.3)/.3] - 75 = 28173 um

Subject: EXTERNAL: [TN] minimum flex bend radius

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.

Bill
