Epoxy inks tend to be more resistant to discoloration than the acrylics that are used more widely now. The acrylic-based inks vary in their ability to maintain color after heat cycles. The technical data sheets from the ink supplier should indicate:

I've never had this problem on an Omniflo oven, but have seen it on others. It has always turned out to be mechanical. A bearing going bad or FOD in the rails. I would pull the chains and carefully check each link of both chains, all of the bearin

Comtra doesn't usually sell directly to the end user. Try consulting your machine manufacturer. On the mechanical belt feeders there are no adjustment. On the electrical feeders there is a turn switch to select the feeding travel of the belt. T

If I follow your description correctly (no fiducial correction occuring between load position and 19000 pulses) I agree that the encoder area is the problem. The encoder may be OK but the mechanical connection from the motor to lead screw may have c

We had one mechanical engineer from a certain customer telling us we had to crop components leads so they didn't protrude through the board, as they could then come in contact with the case as the board was flush. Had I have known then what I know

CKH, if I understand you correct, only some components(for example 2 from 10 parts in one reel) goes wrong. there is one more. How your machine alignes the components? Vision, laser or mechanicly. The problem can come from there. If the recognition
