Great information guys..I am learning a lot. Reading all the info changing the nozzles, pressure and coatings are certainly narrowing the choices. A lot of coatings I have come accross seem to come from the Mould industry especially Teflons etc. I lo

You can leave the booster in the original position and mount two small fans directly underneanth it blowing upward. By leaving it in the original upright position you get quite a bit of air velocity in the small space between the booster and the mach

We work with a lot of larger boards over 24", haven't run into this issue yet. I agree with scott could be your board supplier if they are lower quality, from something as simple as unit conversions in CAD to dealing with different temperatures. A

I disagree with the statement that using pads as fiducials shouldn't be a problem. If he's using pads on the PCB, than he is most likely using corresponding apertures on the stencil. During production, these apertures will start to have paste accumul

UFOS is the language of that generation of philips/Yamaha Surface mount machine. Indeed there are other commands. My program PCBSynergy, generates 2 variations of UFOS that will likely program that machine. Unfortunately my copy of these is in storag

I have some boards that go through the assembly process on our SMT Line mounted on SMT Fixtures. Currently, we are experiencing some quality issues (shifting, tombstones, etc) on some of these assemblies as a result of not being able to keep the PWBs

Worked on these for many years as a Speedline FSE, now doing my own thing. You could have motion or alignment issues in the printhead. The setting in the INI could be wrong, but unlikely. Or are you just using the wrong squeegees. Without a stenc

I'm not sure of the timeframe with which you have to work, but I'd consider sending the frame and mounted stencil back to DEK for repair. I'm not a huge fan of these systems, because I believe consistancy in the process is critical, and these system

Has anyone experienced bridging on topside (solder destination side) surface mount devices after wave soldering? We x-rayed 100% of the placements after smt re-flow with no issues. When the same placements were x-rayed after the tht wave solder pro

Is there anything on the other side of the board? If not the process will be very standard. 1. SMT - place the small parts on your board. It is called surface mount technology. Basically one machine applies solder paste on the board, another machine
