We start to get mixed component leaded and lead-free, we still using leaded solder paste in the SMT process. Do you see this a problem to use leaded process 179 deg celsuis temperature reflow on RoHS compatible lead-free components with same specific

AJ, Thanks for your input, forgot to inform that there is none BGA on the PCB. I also discovered that there was another topic related mixed component that give me support enough. Will inform my supplier to perform the process in the SMT line and not
