Square you say? Wouldnt this give less paste deposition than a circle and basically reduce the standoff height the same as making the pad bigger? Would using a type 4 paste for this size stencil aperture (.013") be a good idea? Thanks JD

You will want the square in this case to be .013" with rounded corners (slight overprint). I do not see why you would need a type 4 paste for this. the aperture as it sits should release well but obviously there is something wrong.

Really you think the 256 is the issue eh? I have some a sample of the type 4 powder size coming in hopefully today. Hopefully that will help, if not its back to the old solder eval drawing board. I love my job...

What is your price difference between the #3 and the #4 powder. ....see where I'm taking this?

Does anyone know of a reputable supplier of quick turn flex that can handle 4 layers on a 10 day turn? Thanks John S

I know that the smallest size available Kapton Tape is only 1/4". Does anyone know if there is such a thing, or where I can get a custom made roll of 1/8" Kapton Tape?

Hi Doug, Can they be mounted on standard FR4 PCBs & reflowed at Lead Free temperatures? Cheers, Rob.

Depends on how many nozzles you will need for the larger board - if its 8 or less (4 per head) then you can take it out. You shouldn't have too many problems with this as with your setup you have one for small stuff & one for big stuff.

That I can do, checking the placement height that is and the clamps. I believe my clamps are 4mm. If your nozzles have survived 5 years how many placements is that...roughly? In the billions?
