First thing is you should be using a 08MPFX nozzle for a 0603 part if you are using a flex head. Then to check the vacuum you should have received a vacuum gage with a nozzle tip that fits on to your spindle and then you turn on the vacuum in diagnos

Good advises thanks. I'll go thru all nozzles and vacuum check today and tell the programer about PD's and nozzle vs shutter. Should I check at the same time all the vacuum filter ? For the placement test, we use the same feeder at the same position.

I use to have that kind of problems with other type of machines and here are the causes: 1- Spray fluxer head partially obstructed (check flow rate) 2- Defective pre-heater probe (manually check temps) 3- PROFILE (last preheat to 280) 4- we sometimes

We had similar problem, the root cause was that the cooling fans on the VME rack were not working and the vision card hangs up if the temperature is too high. Also check the power supplies, we had also a problem that the filter condensator inside the

check your clamping rails and see if you see any little wear marks, we constantly hit these clamps during placement when the parts are too close to the edge. The height of that clamp is either 4 or 6mm I beleive and the noozles will hit them on occ

Check your pick height/depth. Check your feeder alignment. We run 0402s at 0.10 tact. We run 0201s at 0.20 tact, but only because I don't require any more throughput - I have placed them at 0.10 during testing, and there are companies that place th

Vision #1 only looks at the outline of the part. Only enter this info. Do not enter any info on the balls. Vision #1 won't care if it's coming from a tray. Triple check data entered. Check max and min nozzle size values. Most likey a typo in th

I fear your files are not stored in the default directory or your hard drive is full. Boot with a DOS boot disc and check your C drive for program and fiducial information. Try an older program to check if the program structure and vision informatio

True, we weren't just checking for lead at the test lab we were also checking for banned substances in the plastics - PBB's & PBDE's which apparently appear a lot in the recycled plastics used in manufacturing connector bodies; & also the other banne

Vick Russ is very correct. Get the paste material specificatioin. Please get your favorite data logger (ECD, KIC, DatPaq, etc..), attach some TC's and take a profile. This is the ONLY way to know what your reflow system is doing and how to alter.
