Hi Alejandro,
Most pull-test rigs are made in-house; but why do you want to run such tests?
While they will tell you whether or not you have good solder wetting, there
are better (and cheaper) ways of doing this—±and pull-tests do NOT tell you
anything about the reliability to be expected for these solder joints.
