Hi all
Now I have one question for Bow and Twist (Percentage) calculation per IPC-TM-650, 2.4.22
For nonrectangular PCBA, since it has been mounted with components on both sides, it can’t be placed on surface plate, how to test bow and twist?
And for nonrectangular board, how to calculate L,W and D?

Hope someone could reply my question.

Thanks!
BR/Eileen
