<I'll have to try that. I guess, everyone has their own way of fixing bad <solder contacts. I've used the method I described over the past 16 years o <dozens of old mini computers... never had one come back because of problem <caused from the chemicals I use...< < <john Warning... Silicone grease is persistant stuff and one on what ever it's very hard to remove. So a board that requires soldering need that done FIRST then wipe the fingers with a thin film. If you get Silicone grease on something you dont want it on a it takes a lot of P11 (tetraflurocloroethane) solvent to get it off and trying to cook it off with the iron will not win due to very high temperature resistance of the stuff. Stuff like ethanol and Isopropanol (alchohols) will not touch it. Most quality contact cleaners that have a lubricant have some silicone in them. Allison
