Hi mates, I did a recent shear test (destructive test), on a uBGA liken product, and noted the post-shear solder joint, had clean "smooth" visual appearance under the uBGA pad, however the matching pcb pad was clearly lifted clean. Question: 1) how

I need to perform shear tests on components that have been glued prior to wave soldering. Can any one recommend a shear tester and some standardized info on testing? We have had problems with poor glue bonds and would like to implement a test metho

Your customer is correct. Components should not fall a board during a reasonable drop test. A shear test poorly represents a drop test. A drop test represents a drop test very well. If you want to proceed with shear testing, search the fine SMTne

Hello, When we discover the broken caps, there are missing and we can observe only either the 2 terminaisons or a small part of ceramic. The defect is due to a shock during the process but it's possible that the caps are fragilized during an operati

When I was a salty old fart in the Navy, we sent the babes from the turnip patch off on snipe hunts. 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

Dear Colleagues Does anyone know or care to share any information as to typical torque values ( N/cm ) for components that have been placed using screen printing surface mount adhesive, using a plastic stencil ? Are there any industry set shear test
