You should set the temperature at liquidus point of the solder used on the BGA plus 20 to 25*C. So, for tin-lead that would be ~215*C. Most lead-free solders run about ~20 to 25*C higher than that.

It's possible that the flux residues from the solder paste used in your SMT process is not compatible with your water wash process. For instance, some no-clean fluxes leave resudues that are not water washable. When these residues are washed, they de

Does anybody use a paste mixer in their shop? I am looking at one that uses "Psuedo-Planetary Motion" to mix and soften solder paste. If someone answers "yes", has this benefitted your paste consistency and improved your print repeatability?

I am using TopazX2, placing 0603 caps with #72 FNC nozzles. Sometimes, there is solder splash around the caps, being blowed out by the nozzle (?) when it placed the part down. Any idea about the reason and solution. Thanks.

Hello, we are having issues with two assemblies where the Melfs will lift or not solder on one end of the components. Has anyone had issues with this in the past? What can be done to help this? Thanks

Does anyone have success / recommendations for any specific make / model of a selective solder machine. What should I look at? This will be used in a lead free application.

I only have it here as a storage favour, have never run it. For lead free, I made a 2nd pot for my wave solder identical and we switch when required. Pete

CK, I agree with you totally except for the �art� part. Soldering is a �science� of primary physics in nature. The European commission also looked at soldering as art (not science) and thought that RoHS would just change the materials the artist ha
