Is jet dispensing of highly filled polymers possible? I have only seen applications with SMT adhesives, where the filler content is on the order of 10%.

You may not find a supplier with an "out of box" solution. But you might be able to jury-rig something without too much pain and cost. Try this: * Buy a fairly brainless feeder [like an old quad feeder] from an used equipment supplier / broker [sea

Hi, In your case definitely go with a pure time/pressure. If you want to make repeatable small dots later - only Archimedian screw. Another way is jet printing technology, which I assume is very expensive and far away from your case. Regards, Emil

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

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.

Seeing this graphic has me rethinking solder paste jetting as alternative to stencil printing. It seems it's only 2-3x faster 80k points per hour vs 28k. Wouldn't it be better to get 10 time pressure dispensers vs 1 solder jet?

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.

The my700 can dispense 1 million dots per hour. It's not an exaggeration either. It literally never stops moving, and is dispensing without contacting the board. It uses the same type of mathematical calculations that a plane dropping a bomb uses in

Hi, I think that the jet printer is going to work for your process - the key with this device is to maintain it really good so you don't get any clogs. These are very fast devices.

Hi, I have never been able to find an acceptable dispense process for dispensing small dots of solder paste. I currently have an auger screw automated dispense system and can not accomplish 0.010" dot sizes. In addition, stencil printing is much m
