In a previous job, we had torque off requirements for different sized components for our screen print adhesive (non-conductive in our case). We used a torque watch that would measure max torque, so we could test production boards, shear testing was

Assuming that you need information such as the type and size of screw to the recommended torque value. I have found great information from the torque tool manufacturers themselves! There is an ANSI spec but I don't know the specifics. Your torque d

Also, check the website for Assembly magazine, http://www.assemblymag.com, they have some good information on the basics of torque. Determining the "correct" torque value can become very complicated very quickly. The same size screws made from differ

Some thoughts- Torque applied to each joint is case specific. I know there are charts and all, but they don't account for YOUR situation such as screwing a fab to a chassis(or your aluminum screw). If the customer sets a spec then use it. (But i

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

Specifications of testing force are not fixed, but (incase of wave soldering) the value should be at least 120-150 % of the force the wave. So for small chip components we assume that the force from the wave on the component is about 3 Newton, this m

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

We find that the raw BGA's pad sheared surface has the SnPb solder at various Z heights whereas the assembled BGAs pad leave a smooth layer of SnPb along the pad. Like to understand the cause for the difference. Who could guess? Solder joint streng
