Hi Shawn, that you're baking the components makes me think that they are either old, or have been sitting around for a while (or none of the above & you are really dilligent!) Whilst baking will sort out the MSD issues (such as popcorning) it will

Last week, when we turned on our IP3, we received an error on our IP3, which read "Fatal Error with VP Turn Power Off" We had been running product the day before, and the day after we received this error. The function keys are locked and will not w

Fastek, You are correct. I know of machines you can get for 25k that are in working condition. But if I was going to buy one used, I would want it refurbished and calibrated. I would also be interested in support and warranty. I don't know of an

That's my exact suspiscion too. This guy is trying to find some type of "scapegoat" for some unknown defect that nobody can figure out. First, he'll try blaming the solder paste, thinking that the CM is too dumb to choose the correct soldering mate
