Howdy, This subject may be a little off subject, but I have been looking for a source that can give me info for the recommended torque on hardware. What I would love to see, is a chart that can show me, for example a column for the screw size (SAE &

Have been having problems with the above IC but dont know why. Our profile is well within the manufacuters recommendations. We are getting a higher than desired first off fail rate and are concerned. It is not possible to inspect the soldering as the

It�s hard to tell you one good profile for a specific machine cause profiles are mainly dependent on the specific assembly you want to rework. My aproach to this problem is trying to get a close as possible profile as under normal reflow conditions u
