Folks, Question - I believe that it is common practice to use the same forced convection reflow oven to reflow Pb-free as well as SnPb boards in today's world but I was wondering if anyone has experienced any issues doing this as well as what safeguards should be implemented so Pb-free flux residue deposited within an oven does not contaminate SnPb boards (e.g. flux build-up in the oven could redeposit onto boards going through the oven?). thanks again.
