I am looking at dispensing solder paste using a Fuji GLV glue dispenser. This is to enable us to produce prototype pcb's without the need to purchase a stencil. Has anybody tried this before? If so what problems should I expect to encounter.

Does anyone out there have experience dispensing solder paste with a Universal GDM (4716AL) with positive displacement pumps? I'd like to hear any comments on the success or failure of the machine to dispense consistently, effect of temperature varia

The FGLV has a air pressure displacement valve, which is designed for adhesives. A positive displacement valve is better suited for solder pastes. Check with Fuji to see if they offer optional valves.

Has anybody successfully used an automated dispensing system to put solder paste dots on .5 mm pitch pads?? I need to replace some Meritec tsop sockets and I don't want to use the single site stencils for .5 mm parts.

With a standard valve and no-clean solder paste you may get a few good dots. But, repeatability will be terrible too many variable, air-pressure, board height (two post nozzle), valve time on/off, retract height, retract time, etc... A RMA paste wi

What I would ask before actually answering your question is, what is the smallest footprint/pad which can be pressure dispensed/jet printed? Regards, Tom.

Jet printing can reach 80um, whereas contact dispensing is 0.3mm I believe. 0402 pads are 0.6x0.5mm.

And I can set deposits down to 34 um on our my500. I do not have the exact numbers in front of me on the my700 or Essemtec, but they will both be better than that.
