I'm looking for a typical SMT placement defect rate from others in the field so I can judge whether or not we are in an acceptable range. If I give you a board with 200 components (0603, 0805, SOICs, 20mil MSOPs, tantalums, DPAKs and a few 20mil fin

John, SOT 23's on the bottom side is no real problem...as long as you get the orientaion to the wave right and you remember to increase the pad sizees to allow the solder to get to the pads. Soldering with only one wave would be trick as Vinesh sugg
