Re: Why would I want to use photonic soldering for my rework applications?

Reworking BGA with hot air systems (ie, AirVac, SRT) is fairly complicated and requires fairly rigorous process control. Please compare and contrast BGA rework using hot air and your laser based system.

They are a CP40 and CP50. The CP40 is fairly new and the 50 is fairly new but we bought it as a used piece. It is in good condition. As far as I can say everything seems set up correctly. By the sounds of your reply I should dig into this more deeply

Solder Balls at Electrolytic Cap

Electronics Forum | Tue Jun 15 13:36:30 EDT 2004 | John S

We are launching a new product and are fairly new to reflow soldering. A concern that has arisen is a fairly consistent solder ball that forms at an electrolytic capacitor. We changed to a homebase aperture design on our passives to eliminate mid-c

No, raising the solder pot temperature to 800*F will not affect affect your solder alloy. We expect that you had a fairly high level of intermetallic compound generation, but most of that would be included in the fairly high dross generation that ha

Environmental Regulations on Reflow Exhaust
