In a recent I-Connect007 survey on jet printing solder pastes, we asked the following question: "What are the major benefits with jet printing solder pastes?" Here are just a few of the replies, slightly edited for clarity.
Erik Widding, Birger Engineering Inc.: "No stencils and immediate ability to vary paste volumes anywhere on the PCB. Also, very little wasted material, as none is exposed to the environment until after dispense."
Jason Nipper, UTC: "Ability to selectively print without Kapton taping apertures on stencil. No need for stencil, good for test and NPI development."
Stephan Kohler, Turck: "Rapid prototyping."
