Refer to this article, http://articles.jimtrade.com/1/212.htm The main advantage is of course the density of the board. All the advantages for SMT over PTH are related to the decrease in component size. This is a good selling point for your custom

| Also the preheating of the board is done to help evaporate any water/alcohol that is in the flux - water is a big problem in No-clean processes. From our experience, a temp range around 200f - no more than 220f is ideal for the bigger boards, but t
