Solder balls, can be excess paste by opening ST. Do you see the curve still working pasty with lead with alloy "63Sn / 37Pb alloy" has defects?

I agree with DWL's comments. Also, your profile is really really inconsistent. How did you attach the probes to the board? You have a 25c delta in your peak temps. Unless that is from a probe lifting, that is really bad. What type of oven are you usi

Hi all, I have an inconsistent situation. Lately, we seem to have excessive dross buildup in the solder pot which inturn causes the pot to overflow. Has anyone had a similar experience? Here are the details: age of machine= 9 years, flux used= Kester

I am just wondering what other people are using as far as gloves when cleaning the dross out of the wave solder pot. We currently are using welding gloves, but the operators say that they are too big and bulky. Does anyone have any suggestions on wh

Your leadfree dross should float, similar to your leaded dross. It's possible you're thinking about the process for removing excess copper from the solder pot. Following the same process, with: * Leaded solder, the copper floats. So, you scoop the

Horace: You weren't real specific about the set-up of the two machines. So what's the diff man?? Big dross generators are: 1 R Woodgate says that pump speed is the biggest driver to dross production 2 Chrys uses low dross cast bar: Alpha HiFlo 3
