Jigo, We have never had a need to do internal testing on solder paste, and your paste supplier should be able to tell you what the correct operating temperature range is. All of the big names in solder paste have tight quality control and I suspect t

Dear Hussman We use automatic machines on mounting PHILIPS and though quality and velocity of their mounting are very good, the girls occupied with quality control can not on 100 % to check quality of the soldering FLIP CHIP and BGA!!! Pavel
