PWB strain specs?

PWB strain specs? | 30 July, 2008

Folks, I'm looking for some specs for the maximum bend or strain that should be put on a PWB. Not looking at the solderjoints. I'm concerned with localized bending of the fab and what might be a reasonable limit for that bending. I've measured 1053 microstrain, which is borderline for some solderjoint reliability papers. I'm wondering what there effect on the fabs is.

Note, this is in final use application, not from some test fixture.

Not quite what you'ree looking for, but may be interesting: JESD22B113, Board Level Cyclic Bend Test Method for Interconnect Reliability Characterization of Components for Handheld Electronic Products
