When we had problems on our Omni 5 with fluctuating chain speed, the problem turned out to be the Dart speed control board. After replacing the board the problem went away.

Bert, Let it fly. The machine was built to run at 100% speed for certain components. I recommend finding a copy of Fuji's "SMT Report" to help you with speed settings for different packages. You can control the head speed on a part by part basi

Asymtech glue machine would do the job..different heads are available. Fuji GL series machines are also good but require a offline controller Even with PTH components Screen printing glue is still possible,some call it pump printing? what type of pl

Our board suppliers tell us, there is no specification they use for HASL thickness, other than "coverage". They also say they have very little control over the HASL thickness. This was not an issue for us in the past, until we started using Pb-fr

Try lowering your blower speeds on the bottom zones. Works as well and lowering temps but easier to control than balancing your delta T from zone to zone.
