Sheer strength of a BGA assembly

Has anyone ever run across a specification for the sheer strength of a soldered BGA assembly. We are looking to qualify a process and would like to have a target number to shoot for. Thanks

There is no specification. Shear tests are very material / operator dependent. BALL SHEAR TESTING OF RAW BGA DEVICES: A total of 3 devices were subjected to ball shear testing. Results of the testing indicated shear values in the range of 0.7-1.25
