well, the problem we have is with the shaft cam (in the mtu), when the machine moves the trays upward there is a vibration that moves to the components, we need change the shaft cam, but meanwhile we replace it I need to control this problem and I be

I had something similar to this on a different type of machine but it turned out to be a broken wire terminal connector at the switch causing intermittent connection. Often with safety circuits they are kept high and brought low or interrupted to dis

I wouldn't think the vibration from weights dropping would be significant enough to effect the SMT machines. If you are concerned, look into placing vibration dampening pads under the machine feet. you don't need anything fancy, just neoprene pads wo

I am mainly concerned with physical vibration. Will machine to machine alignment be affected.

You can't really use a pasted board to troubleshoot the program as any components not on target simply slide off with machine vibration and movement as they won't be held by the solder paste. Whereas on double sided sticky tape they remain in place

dedicated fixture works best if the board is very much populated. But if the parts to be inserted are less than 300components, adjustable fixtures may be used. But the secret of good insertion is a precisely measured tooling pin to prevent the boards

Hi Fred Thanks for your advice. That can cause bcoz may be Machine Vibration also. I did not check whether the parts were already upside down before advance.I'll do it in next run. We found that other diodes,see atached pic, were no troble duri
