Ideally first you need to analyze the residue to see what it is. We had a customer with white residues after wave and elemental analysis revealed tin.

I have used the Versaflow 40/50 which is the model before the 3. The machine is a very good machine, the electro magnetic pumps work well and do not cause alot of dross.

We own two KISS 305 machines from ACE. Extremely happy with the machine. More so, with thier support. The support is the best from any vendor I deal with which is a critical part of our operations. Another thing is thier continuing R & D work. They

We would agree with Pete B about both the under etching as a possible issue and you will not be able to remove this gold. Another possibility is the solder mask (plating resist) hasn't been taken right to the edge of the pad.

PCB Supplier made an EDX anaysis, the found a chemical trapped in the holes, and some burnt burrs, according to what they say this stains are over the solder mask & silk, so they do not affect functionality.

Are the conditions (Bullets) under the IPC Acceptable and Defect sections "ANDs" or "ORs"? In other words, does every condition under a section must be meet to be Acceptable/Defect or meeting any one condition suffices?

We've done the same as what Woodsmt has suggested. Bread pans and a ladle. Slow going but safe. We did not have to add anything to the pans to prevent sticking. Woodsmt, did you have to worry about the pot heaters over heating while draining?

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

Hi, I was using different brand machine but it will behave the same way as yours when it is dirty or clogged. Try to clean your nozzle and your supply mechanism(pump, propeller...) and you should get a smoother wave. Good luck!
