We are now running SMT ROHS assemblies. We are losing some upside down parts in the reflow oven when running the 2nd side. These are parts that do not fall off the leaded version. Anybody else having problems with this? What are you doing to stop it???

Try using the loctite(glue) during the top side process. Other way is to separate bigger component IC on the last process (top side).
