Thank you- my point exactly and it starts in SMT- operators pulling the wrong paste from the fridge, touch up using the wrong solder wire, etc. My solution- GET THE LEAD OUT!!!!! I'm a CM- high mix, low to medium volumes. No steady all day every day

We use SN100C for wave soldering and hand Lead free soldering and have had very good results. The wire cored solder for hand soldering flows good and makes very good solder joints. The SN100C in the wave solder machine also works very good. We use
