Shear Testing

Shear Testing | 1 June, 1999

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 method to sample boards for acceptability.

Thanks in advance,

John Sims ACD Tridon

Marc is at the following as he recently has been involved in similar studies:

I used a Chatillon device. If you would like to know more, feel free to contact me.
