Hello Could somebody inform us about real consumption of lead free solder alloy SN100C on your wave solder process. We do not use some antiaxidant and had had alloy consumption about 1 kg per hour. What is your experiance? All sugestion will be wellcome Peter

What volume of boards are you putting through. 1Kg per hour does sound very high but then again it does depend on volume Using an antioxidant is a must with Lead Free some alloys have additions in them to start with but those drop out with use so the rate of dross increases rapidly. A good supplier will offer you antioxidant to run with it. As a general rule of thumb if you use a good antioxidant then dross rates for Lead Free are half that of Leaded solder if it is running higher then you may have a golden/yellow colour to the solder and dross will increase.

Thanks Greg Our main problem is that we are putting small number PCB through, about300 PCB, size180*250. Such number order our customer in week. In result we got such high solder consumption and high production cost. We will tray to use antiacidant. Bye for now Peter

If you are saying you're going through 1kg/h while only producing 300 pcbs a week and the rest of the time the machine is standing still, then 1.there is something seriously wrong with your machine or 2. check if an operator is suddenly covered in shiny tin chaines and rings.
