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

For 20 mil pitch applications, two important properties to evaluate are (1) dispensing volume consistency, (2) slump performance. As to the dispensing equipment, positive displacement will be the better choice for better consistency. Nozzle size is v

Why do you want to apply paste by dispensing ? Have you given up all the solutions for your solder paste printing? The cost effective way of using your Cam/Alot is to dispense adhesive. And use your Stencil Printer to apply solder paste. That's what

Can't find "WS601" on the Alpha site. What is that stuff? So, with nothing to go on, I'll just guess ... Yer probably cold welding the solder particles together. The nozzle size (inside diameter) determines the dot size. * With glue, small dot si

Bing, thanks for your reply. The nozzle that I will order needs to have standoffs, because we paste and then dispense glue (not my idea) So using the dimensions that you gave me I found the one that will work with our aplication. Thanks again for

How do these factors affect paste selection? How does paste selection affect nozzle slection?

However the OP is talking about a machine that replaces a placement nozzle with a dispense head. This is a $20k upgrade that runs at a fraction of the speed an inline stencil printer or Mycronic dedicated dispensing machine. Essemtec offer a similar

All, I have a reoccurring issue with the Alpha-Metals WS601, water-soluble paste in that the size 20 nozzle of the auger-type dispenser on my Camalot Gemini II clogs up rather frequently. Every few hours we are having to go in and clear out the nozz

John we paced through the same question recently. Both automatic dispensers and printers can be used to deposit SMT adhesive or solder paste on substrates with a relatively high component density. Dispensers are superior to printers in terms of exa
