temp stress reliability test for SMT solder bonds

Electronics Forum | Thu Apr 09 12:25:43 EDT 1998 | Dave Hammond

I am currently involved in a reliability project related to SMT QFP and TSSOP fine pitch solder joint reliability. I have decided to use a temp chamber for stress testing. Is there a test standard that covers this? I am also a bit unsre as to whether

reflow solder joint shear strength

Electronics Forum | Wed Jul 03 15:40:17 EDT 2013 | davef

Shear tests are [in my opinion] senseless. The shear stress you measure depends more on the shear rate and on the point where the force is applied than on the grain structure. When shearing a component, you not only apply shear stress, but also roll

Solder joint strength

Electronics Forum | Tue Mar 22 07:39:05 EST 2005 | davef

There is no standard. This is a relative test. If you wish to do tests of this kind, we suggest to pay attention to the following points: * Shear strength of soft solder depends on the deformation speed applied. The faster the material is deformed t

Is there any chance that the boards were mechanically stressed (for instance, installed in a fixture) before, during, or after the testing? I'm just looking for other possible root causes.

Continuing, I�ve optioned about the uselessness of shear testing of solder connections on this forum previously. So, the points that you make about the elusiveness of developing a standard for measuring solder connection strength is well taken. I�l
