Personally I would go for one alloy it just makes it all simple to control. I have only used tin/silver and tin/copper so far with good process results. Reflow is relatively straightforward, I have had more shorts with wave on tin/copper. To date I

I have an application that requires soldering pieces of metal (copper plate and copper fins to make a heatsink). Each piece is about 1 lb. I cannot test it in our reflow oven (5 zone) since the piece is about 3" in height. Has anyone attempted to
