Profiling on rail vs mesh conveyors

Electronics Forum | Mon Dec 14 09:22:04 EST 2009 | jammm

I need to profile a single sided board thats width is less than the profiler. Is there a difference in profiles when one is completed using the rail conveyor versus just laying the board and profiler on the mesh conveyor?

jamm, As with the other answers you've received, I agree there will be a difference. The question is will the difference between the temperatures of the product profiled at the mesh belt put you out of spec when you run production on the rail? the ke

We've got an MPM Accuflex printer that generally works great, but we've had a recurring problem. The powered rail (rear rail) fails to initialize. Sometimes all it takes is restarting the machine to get it to work. At the suggestion of the repair

Yes, there will be a difference. When the board is on the rail conveyors it is closer to the top heaters and farther away from the bottom heaters than when on the mesh conveyor. That difference will create different temperatures on both sides of yo

We had this. The anti-backlash nuts were binding. We took them apart, chased the threads with a tap and re-assembled with slightly less pre-load. Hasn't been a problem since.

I have moved golden boards from chains to mesh as I got tired of fishing t-couples under the chain rail. I saw a 3-5 deg. decrease on top-side parts peak temp. (all t-couples were on top side). I had to bump zones 6 and 7 a few degrees to make up f

I dealt with the same issue for a month or so. We jumped through a lot of hoops, replaced both lead screws, verified the motor was good, a ton of stuff. Ended up being an intermittent wire connection between the control board and the conveyor width

We also had this problem and found similar results with the anti-backlash nuts binding. We went through the process of cleaning the lead screws and the nuts which resolved the problem for about 6 months only to have it return. We learned that the
