Dave, Thanks for the info! Yes, I have read the IBM document and realized that I was missinformed about the paste volume. I need 5000 to 5600 cubic mils of paste. Running the numbers I get a 32 mil aperture with a 7 mil step (the rest of the board

I hate getting "roped" into math stuff, but here I go again ... Area of aperture = volume of paste / stencil thickness = {[5000 mil^3] / 5 mil} = 1000 mil^2 Side of the square aperture = Sqrt of the area = [1000 mil^2]^1/2 = 32 mil Diameter of ape

Hey MoonMan, Did I catch in one of your fabulous threads that you're using Tetra stencils? I'm anxious to find out how you're liking them. We we're all set up to go to Tetras, then mgt decided to close down our factory - Dooop! "Foiled" again! (te

We are not doing this right at the moment but I have done it with great success. Of cource it depends on your pad layout we have a 20 mil gap in between pads, we printed at 10 mil wide with a 5mil stencil. I will try to find the glue we used, I kno

J Rose at EMPF says: The introduction of no-clean solder fluxes in electronics manufacturing has given rise to greater levels of solder balling simply because the opportunity to remove them in the wash process does not exist. They are typically cause

The tendancy always has been "when in doubt, touch it up"... this is not the way to "verify the process" and is not the best strategy for multiple reasons (unessecary rework, additional labor costs, as well as making the solder joint more brittle, [i

Yes I would, most of our old Yamaha machines (before 2005) will do 30-35 microns @ 3 sigma with the fine camera option. Our Jukis with His res camera's will hit it too. You should be OK with most things after 1997 with the right camera choice (whic
