Are you referring to a feeder or just a platform to place trays on? I'm looking at a used Topaz purchase right now and am trying to make sure I understand the language. Have you tried any of the refurb houses for this stuff?

If you're using vaccuum to hold the board, too much vacuum can cause bad print. This generally occurs during snap off. You can either decrease snap-off time of reduce vacuum.

Look for a new shield. For the exact reason already mentioned, most shields are available in two piece units. You install the frame when installing everything else... You clip the top on later.

Dave, I had the same problem in the past. Use fresh paste and a slightly higher profile. My guess is that you may not be completly reflowing. It worked for me. If that doesn't work you may want to check the bga itself, make sure balls are universal.

You're correct. So, you're thinking about putting the PTH parts on the same side as the SOIC LED, making the top into the bottom, right?

Rob, just curious how did you overcome this through stencil design? Did you play around with foil thickness and aperture geometry?

Your DEK could read non-blackened fids? Wow, you must have bought them from Superman. Or did you just teach baord pads and stencil openings?

A couple of Fuji 842E Chipshooters if you are buying new, they will eat this kind of work, major service every 3 years on a single shift, and you can leave them to your kids.
