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

Can anyone tell me the differences between the CP6-4000 and the CP643? Is the CP643 able to place a wider component range? Does the CP643 have some sort of vision system while the CP6-4000 doesn't? If anyone has the Fuji Specs on the CP643 and could

We have 30 years of soldernig experience, 25 years in soldering robotics, and have had laser based systems for a few years now. I'm not sure you need a laser for this application. It's really going to depend on whether or not an iron tip can get in

I would suggest accepting components only in paper tape. I have had better luck with 0402s in punched paper over plastic embossed tape. You can also pick with oversized nozzles if your vision system does not give you trouble with seeing the nozzle.

Like most things - "it depends". There just isn't a simple formula for applying general air exchange rates. Your baseline should be doing some air quality (industrial hygiene) testing to see what types of exposures the workers have. THEN, you can
