Have you tried turning the theta manually to feel if it is stiff or having a harder time turning. This will cause Quadalign errors. also be sure the handling is not set to 10% on the theta this is also a problem.

Dude - check the centering jaws as well. If they're off a bit it'll do this as well. Is it just mechanically centered parts, or optically centered parts also?

My machine TP9-2U have the same problem. I use the camera to walk through the program and it is off and not repeatable. I think the machine has backlash but I don't know how to tighten it up. Can you help??? Thanks, -Michael

This is the TP9-2U machine and have about 2000 hours on it. When I used the camera to walk through the program, it is not repeatable.

Bert, This is a mistake by Fuji (yes they do make some). The fitting is on the table but is blocked by the retainer for the lead screw sleeve. Jerry

Always could go get a stethoscope and that seems to help isolate a problem that you may be having. I have one of these on hand because they come in handy.

Is the flux rated for lead free? These higher temps will cause most lead rated fluxes to burn off prior to the wave. Jerry

Likely causes of this are: -Preheat temp. too low -too much dross -uncured epoxy -PCB contamination ...also varify the solder flow over the wave is smooth.

MF300S is quite an old flux, & a lot has happened since then on the flow solder front - are you sure it's designed for Lead free, or is it just a traditional flux that SHOULD work OK with Lead free?

Sounds like your flux to me. Since you cannot change the board or the machine, changing flux would be one question mark you could take away with a phone call and a sample. You will really be surprised how different fluxes can affect your final prod
