I have asked several questions regarding plastic parts with good results, but still have one issue. Throughout IPC-SM-786A there is reference to baking out plastic parts at 40C and <5%RH. HOW? Who has the equipment to bake under these conditions? I assume you need a special oven to keep the humidity low... A regular oven running in a standard ESD safe environment will not have such a low RH inside...
