Steve , I use a general set of guidlines when developing reflow profiles: Ramp rate to 140 deg C - 50-60 seconds Time at preheat (140-160 deg C) - 90-120 sec Time above liquidous (183 deg C) - 45-90 sec Time at peak (215-225 deg C) - 9-12 sec peak t

All, I am having a problem with joints being soft after SMT. Especially 25 mil and smaller parts. It seems as though you can slide the leads right off of the solder. It takes only about 30-40 oz. of compression at 45 deg. to move leads off of join
