Most machines for lead free have adjustable conveyor angles (4 to 8 degrees). In the good ole days with lead, we typically ran at about 6 degrees. Often we see closer to 4 degrees with lead free. This is very common, and provides longer immersion

Hi all, How can I convince my equipment purchasing supervisors that to properly solder BGA's a 7 zone oven would be far superior than a four zone? We currently own a 4 zone oven and I'm fearful that the BGA will not get adequate heat for solder
