Screen Printer Eval

My printer evaluation has come down to the Fuji GP-6 or the Dek 265LT. I'm looking for experienced opinions on both of these options, we're currently running an older vintage Dek 265 printer that gives us constant electronic system problems. The vision recognition can't seem to find it's marks know matter how many times you fine tune the threshold, also we have initialization failures that attribute to slow start-ups. The Fuji chipshooters we use have robust electronics but we have no experience with thier screen printers. Are they as reliable? Do they run with minimum downtime? How does Fuji's hermetic squeege compare to the Pro Flow? If anyone can help me answer these questions I'd be anxious to hear from you. Thank You!

Thank You! | The DEK hands down out performs the Fuji's. We now have 6 DEK 265 GSX's, replacing Fuji printers (very clunky) and I just finished a contract using two LT's. I have never been more impressed except with MPM 2000 and 3000 series machines.

Concerning DEK, it is a very robust platform with very a precise fiducial recognition system. It's software is a comparitive breeze to use and machine setup is great.

So many options are available, including ProFlow (we are now preparing to install), auto bottom side tooling, etc. I do have some netative information about ProFlow that should now be resolved with carefully re-engineered fixes.

My past experience with ProFlow had cartridges half empty and not capable of being totally evacuated, leakage, misprints, etc. I've been reassured by DEK and other users these problems are a thing of the past. When ProFlow works, the prints are outstanding with near perfect formations as X, Y, and Z profiles and volumes.

The machine, as we use it, has no down time and keeps up with our extensive Fuji and BTU lines (again 6 of them). We do very large panels demanding the 350mm cartridges though currently using squeegees. The current print quality is excellent as we are now using QC-Calc on line as networked in real time and/or batch mode to verify all board and squeegee relationships.

Service is very good and American though the manual (on CD) is a bit British. The service and technological support gets better all the time.

Though not an endorsement for the machines, I would recommend DEK number two overall to MPM. Maybe my reasons relate to one issue and that being razor sharp board clamps capable of cutting of the tip of one of my operators fingers while setting up the magnetic, bottom side, support pins.

There's much more, but Fuji does what it does best - "shoot em" fast,

Thank You! | I would buy the DEK over the Fuji. I agree with what Earl says. DEK/MPM are the experts in solder printing. Have used DEK 265 series for many years. Purchased one of the first 265LT machines about 2.5 years ago. Anyway, we use the 265LT all the time. Almost no down time due to machine failure. Only problem was on the understencil wiper. Went through a few motors due to wiper paper winding up stopping the motor. Fixed this by adjusting the paper clutch.

Your vision problem on your old DEK 265, I believe, is due to an older vision system. I believe Dek switched to Cognex vision due to the problems with the old vision system. Can't remember old vision manufacture. I have had experience with both vision systems on 265 printer. Dek with Cognex vision is the one you want. When I purchased the Dek 265LT, the vision on MPM machines was not good enough to see thick film hybrid fiducials. Fiducials are silver on white background. Almost no contrast. Dek 265LT works perfectly with this type of fiducial. I don't have the stencil fiducials filled in black either. Don't need to anymore.

Thanks,

Chris

They wouldn't happen to be the Mark I model would they? Those were pretty tempermental and DEK did upgrade to the Cognex vision platform for better performance. I have a 265GSX and an LT on the way. I'm happy with the improvements that DEK has made. I don't have any experience with the Fuji printers so I can't offer any help there.

Thanks, Justin
