There are several different technologies in the industry today to assist in the out-gassing of flux cores. On automated soldering systems, there are two main types of perforating solder feeders: - Hole Drilling - "V" Scoring By perforating the so

Electronic devices required higher speed, I/O capability, and density to meet standard requirements. Automated robotic soldering solutions that meet the demands of applications are too challenging for hand soldering. Manual soldering, even with the m

but we do not have laminate preheating on robots. There is no flux separate application, the flux is in the soldering wire

Try baking the boards; you may have a moisture problem.

Are you using nitrogen in your soldering process?

@Capse, No but the machine has such a construction, I can not this change

Hello I have the problem with selective soldering on the robot. Thin balls appear on the laminate. The tin sometimes shoots...? and then the balls are a few millimeters from the soldering point. I tried up or down with temperature, but it did not wor

If N2 is not an option, the cut wire feeder or drilled wire are your best bet for now. You need to optimize wire feed rate as well. The solder joint on the robot takes about the same time to form as in manual soldering. If you need to speed the solde

I would start with checking the flux amount and trace and the thermal profile(preheating is important) for this assembly. Then I would consider changing to another flux and run it again.

Thanks from your answer. A few days ago the supplier told me about these rolls. Now I am waiting for them and I will make tests. Maybe I will also try to reduce the ejection speed but this will lengthen the process
