Proper method to bake PCBs

Proper method to bake PCBs

Also, you need to allow enough time for any of the moisture adsorbed in the inner layers to make their way out of the PCB. Depending on the board thickness this can be 4+ hours. Since you want the moisture (and other solvents, possibly) to escape, the best way to do this is to have the boards in a rack, vertically with some space in between the PCBs.
