Part 7: SOLID STATE CIRCUIT BOARDS 7.5 Circuit Board Removal and Replacement General Notes: The circuit boards should always be handled with care. Keep the board it its packaging until it is time for installation. Do not place the board on metal surfaces. The boards have a protective coating that resists electrostatic discharge (ESD) but it is good practice to touch a metal surface with your hand to discharge any static built up on your body before handling a board.
