Does anybody have a practical experience with solder paste dispenser for small-scale production (prototypes, or 10-20 pcs. batches)? What ptich size is realistic? Let's say that the speed is not an issue, but the quality is. - Deni

For what it is worth, we are purchasing a dispensing system including a Robotic Arm, Positive Displacement Valve (as opposed to volumetric displacement) and Controller. We have purchased this unit for doing lead free 20 mil dots at 30 mil pitch in s

My group supports a couple hundred lines all over the world. Most of them use squeegees but a few use either the MPM Rheometric pump heads or the DEK Proflow heads. I absolutely hate the enclosed heads. Flux separation, compaction, and the print q

The paste dispensers work well as long as the humidity in your shop is properly controlled. If it gets too humid, and the paste gets "soupy", then it will take less air pressure to dispense it onto the stencil. Paste dispensers use a controlled, pre-

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c
