If I understood on that electronics, you have a bot and a top side...and problem is when is first side in oven second time...So I thought that the temperature in the lower part was lowering..and increase in the upper temperature part in your oven. th

I got a 3000 that is acting crazy. After a print, the board is unclamped and the Z-axis lowers. It continues to lower until it trips the limit switch. It is suppposed to move in the Y-axis to line up with the tracks while lowering in the Z-axis.

@Alexei Shkolnik Ah, I hope this doesn't become a problem. But if it does perhaps we can redesign the whole system? Push the components with a pusher that's connected from above rather than pulled by a magnet below. Perhaps the pusher can still clim

I concur with your second approach. A profile needs to be tailored to the design of the board, the components, and the solder paste. Your first approach seems to try to balance lower quality soldering with a lower process complexity.

Hello, Dr. Ning-Cheng Lee The melting point of solder PB-Free its to higher do you now the lower temperature of an PB-Free and its constitution. Its true if the solder paste have in its constitution a Bismut component the melting point its lower?

We have very good results with a mixture. Lower 1st and 2nd preheat is convection, 3rd lower is calrod. No upper 1st and 2nd, 3rd upper is IR. With this combination I have found no challenge that could not be turned into a good profile.

Try lowering your blower speeds on the bottom zones. Works as well and lowering temps but easier to control than balancing your delta T from zone to zone.

Is the mechanics ok with the raising and lowering into the vapour ie no small movements that could be moving the part ? Most Vapour Machines have a lower and raise mechanisim so movemnt of parts can happen if not smooth, especially when coming out o

Is it the correct type of thermocouple? If it is designed for a K type and you put a J or T the reading will be lower. Also a bad connection can give a lower reading.

Need help on how to fix or temporary fix to bypass the "Rear feeder bank in lower position" error for the Juki 2080 machine. Even replace with different feeder bank won't fix. Any suggestions?
