For the applications you mention you would probably want to resolve details of at least 8 microns (0.0003") which would translate into a bare minimum resolution requirement of 60 to 100 line pairs per millimeter at a minimum geometric magnification o

Hi, Does anyone have guidelines on minimum SMT component spacing for bottom sided wave soldering? I am looking for general rule of thumb in wave soldering bottom side SOTs, 0805 & 0603s. How about minimum through-hole lead to pad distance? Peter
