I think it might be the feeder banks, that is causing the problem. I've tried picking a SOT-23 component using head 2 spindles 1-4 from a rear feeder bank and it is picking off centre. Doing exactly the same, but putting the feeder in a front bank it

Hi All, Has anyone out there used an Airvac DRS-22 for RoHS rework on lead free BGA's?

Does anyone have a solution to using thick tape on quad feeders? The feeders are not strong enough to handle the thicker carrier tape. This causes much downtime and frustration.

Some guys used to hang weight on the spent tape with a binder clip to help pull the tape through. Not ideal of course, but may help in a pinch...if you try it, you'll have to move the weight(s) up every so often.

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?

Not an expert on PCB manufacture, but it looks like mask from other side of PCB flowed through vias before this side was masked. Is it possible previous vendor masked this side first, or used film-type mask which would not flow through?

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.

I just wonder anyone had the idea of solderability test for through hole by using a wetting balance equipment? I read the jstd002/003 however my feel is now our machine (metronelec st60) is not capable of this test?
