. The flux vapor exhaust volume is approximately 100 to 125 scfm (2.8 to 3.0 m3/min) maximum, while the waste cooling air volume is approximately 200 to 225 scfm (5.6 to 6.2 m3/min) maximum

. Does IPC define Thermal ID and OD? I don't find explanation that define these diameters. I use CADSTAR software and Thermal ID and OD are differently defined

). "Therefore, the calculations for ‘‘S’’ minimum and maximum dimensions are as follows: Smin = Lmin - 2Tmax = 5.8 mm - 2 (1.27 mm) = 3.26 mm Smax = Lmax - 2Tmin= 6.2 mm - 2 (0.4 mm) = 5.40 mm Stol = Smax - Smin = 5.4 mm - 3.26 mm = 2.14 mm" Section 3.4.1 discusses the reason for creating New_Smax
