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?

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.

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 all, We plan to buy solder paste height measurement machine. However, not sure which is the better one..2D or 3D? As far as I know,3D is quite slow and but more accurate in term of measurement result. Pls share with me if anyone who has this e

Hi, yes may be 3d is slow but it gives you great results as it shows the height while 2d picture shows error when the paste in your machine appears to end i.e. when it see that the pad starts to appear. I don't know which company brand you prefer but

Good Morning, We have a 3D solder paste inspection machine. We purchased it on a recommendation from a consultant. We are a CM high mix low volume. The President of my company has attended some seminars and meetings where it was conveyed to her that

Seminars and meetings are the best way to get a clear understanding of a machine's capabilities. I have found that the manufacturing engineers will oftentimes skew the results of machine evaluations with facts and data. In practice, I've found it
