We have already started to ship ROHS products to our customer since mid of last year. So far, I do not encounter any problems that you describe. Have to check with your flux manufacturer, is it for leadfree process?

Yes, we also never experience erosion phenomenon on our solder pot. We are currently using one Sn Cu based alloy, which is SCS7.

SS EROTION WITH ANY SACK ALLOY IS INEVIDABLE GETTING A YEAR OF USE IS ONLY BECAUSE YOU ARE USING SACKX MOST OTHER SACK ALLOYS WOULD HAVE CAUSED MORE DAMAGE IN THE SAME PERIOD.ED
