No clean and foam fluxing is not a very good process from my experience. I know that the flux manufacturers claim that they are suitable but I am not sure what "suitable" means. I would bet that you have very inconsistant flux coverage. How often

Morning Mike, We use Pb63/Sn37, Alpha Metal alloy. Solder pot is at 250 C. The profile of board after Preheat about 100 C, Lambda Wave about 220C (use both Lambda and Chip wave), DWell time 2.1s ~ 3s. Conveyor speed 1.5 in/min. We run by bare board a

With DIP type components, a sub-par fluxing method (foaming a no-clean), and a chip wave where one is not needed are formulas for bridging and insufficient wetting. If you have SMD's on the wave solder side of the board greater than 0603, and no SOT

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

Are you using nitrogen in your soldering process?

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

First of all, more info is needed. Solder shorts can be caused by much more than flux. Is the solder short always in the same spot or all over the place? More detail please.

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

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
