This sounds like sales-type teaser posting, but let's see what we get. When comparing convection to IR BGA rework stations, IR stations perform poorly when: * Evaluation board has no power and ground planes. Worst case PWB as IR energy from bottom h

Thank you for the answers to my questions. We are running two-lead LED insertions. Most of our PCBs are square between 9" and 14.25" in a 16 x 16 array, so pitch ranges from 0.52" to 0.90". Further complications are that most of the boards have th

good * No IMC => bad Intermetallic growths are diffusion limited, and therefore the thickness of the intermetallic is given by: z^2 = (Do)(t)exp[-Q/RT] Where Do (m^2 s-1) is the diffusion coefficient, T(�K) is the temperature, Q (J mol-1) is the act
