Is the mechanics ok with the raising and lowering into the vapour ie no small movements that could be moving the part ? Most Vapour Machines have a lower and raise mechanisim so movemnt of parts can happen if not smooth, especially when coming out o

We don't know dip about vapor phase soldering, but we can't help but wonder how well the leads of the component match with the pads on the board.

Hi, I also paid attention on the solder balls.. I thought it was because of the pop-corning, but the customer told me the component was not damaged.. Regarding the bunch of tented vias, I need to ask the customer about that. Probably, they have unpo

I'd be more concerned with the pcb itself then I would be with standard SMT components. Are you using a PCB with a high Tg? (170 degrees C or greater)

Questions are: * On what portion of the second side of the board [eg, solder only, solder mask only, etc] do you see this white hazy residue? * Could you attach a picture? * You mention cleaning this residue. What have you used to clean the residue?
