Marlies, Larry's correct. The terminology used to describe the nozzle is normally brought about by the methods at which the machines generate the "vacuum". Good job Larry, it's like you just won Fuji's WHIZ-QUIZ!! Have fun all!!!!!!!!!!!

well... it depends on what you are placing. Many odd-form placement machines, like Chad or Jot, use some sort of mechanical gripper as a "nozzle" without vacuum. John Thorup

There are two types of nozzles most commonly used nozzle is vaccum type. but when it comes to odd component which is not standard either plain form. must use machenical grapper to pick up the component

What does everyone use for stencil apertures on D Paks? What's the best way to keep them from floating during reflow?

Hi Larry, you might find something looking for the thread "D-Pak misalignment Problem - Kantesh Doss 23:43:23 12/02/1999" Good luck Wolfgang

We use a homeplate design with 80% coverage on the tab, and 100% coverage on the leads 6mil stencil. All of our stencils are laser cut electropolished. We have had good success with this.

Hi, Can anyone tell me when are bent leads too bent to be straightened again. I'm thinking about the strength of the lead where it meets the housing will be weakened the further you bend it. thanks.

Hi, I'm facing smear after printing on DEK288 using reverse squeegee at the edge of panels. I've checked the fixture, printing parameter, stencil, solder paste. What else can I do?

Tracy, I would check the squeegee blade for wear at the edges. Also, check the squeegee pressure to ensure it is not to high, forcing the paste between the stencil and the land, causing a smear. Good luck.

Check the print gap and check the clamp edges, sometimes the clamps is damaged causing a distance between the PCB and the screen. Good luck
