Here’s a quick post on how a board looks like after coming out from the reflow oven using our Arduino compatible reflow oven controller shield. Look at the curvy solder joints of the components. It ain’t that shinny because it is lead free solder paste. One of the main advantage is, if your solder paste dispensing (either through syringe or stencil) is at the correct amount, I’ll bet that you’ll have zero rework on the boards that came out from the reflow oven!
