We had an order of 50 PCBs that after reflow, it was discovered that we had 
tombstoning and quite a few components that didn't solder correctly. We have 
traced it to the operator using an incorrect profile. I've been in the business 
long enough to remember that you could run a board through the wavesolder 
twice, without damaging it. Does the same apply to reflowing SMT? Can I re-
run the boards through the reflow oven again? We are a small ECM that has 
been in business for 20+ years and we have never had this happen before, but 
I am hoping someone can help me out.
