Have you looked at the cover tape wheel on these different feeders and made sure that they are turning correctly when the feeder is advanced? There's not too many things that could be wrong, either the wheel isn't turning properly and keeping the co

I am interested in performing SMT Assembly on flex boards that would be a couple of inches wide but 2 to 5 feet long. Obviously quite a challenge. I would like to hear from anyone that may have seen anything similar done, or at least has an idea of h

Also Rehm Thermal Systems Ovens would be worth a look... They are well made, ALL stainless tunnel , 3 phase blowers, highly realiable, and they have new entry level series called VXC Series starting at 6 zones+, but based on same tech and build as t

We will try both the solder mask and the .001" Kapton and see where we end up with each. This is a fine pitch dual row QFN and we cannot afford too much paste on the .004" stencil we are using. We have experienced shorting in the past with .005" sten

Are you concerned with physical vibration or electronic interference? If you can see your morning coffee have "rings", screen printers may suffer. Trains are a monsterous source of electrical "noise", just by thier engine (electric and diesel) not

IIRC - After completing the reflow, you'll need a soak in DI water for a few minutes (be patient), then peel with a tweezer, and finally use a soft brush to remove the extra bits. At least it used to work that way with the Winslow/Solderquik product.

1) I think maybe not, however having said that, our conveyor does not work between the final placement machine and the oven, in the early days before I became a "experienced" operator in pulling the board out of machine running it along the track to
