From some previous article I read (sorry, don't have citation), I think the main reason for limiting reflow count was due to via integrity.

Yes, he is correct, it is probably a sensor. That does NOT mean a sensor is bad, just that it has not been activated during a time limit or servo count. Watch what the last 2 or 3 things it does before the error.

Hi, thanks for your answer. I was thinking to go even deeper by counting the hours the paste was exposed, but it probably doesn't make a lot of sense, especially considering the fact that my operators will add paste when the level goes too low. I wi

Hello, Can anybody tell me what is the life span of a stencil? How many stokes on the stencil is the maximum count to have PREDICTIVE maintenance on the stencil.Thanks

That is the optimal solution. Most placement equipment have very accurate methods to count the fall off per part/nozzle/feeder. Tie that together and you would be golden.

Does any one know how to calculate BGA height change after reflow oven? I guess the calculation will be based on the component size, weight, ball diameter and ball count of the BGA, but how to get the actual height?

Does the component supply count setting do the trick? We have picked simultaneously same part number in two different feeders with our KE-2020L.

Hey man, can you please suggest what you do for traceability system to count cycles of the stencil. Is there any special setup for that or just a Excel sheet with formulas.?
