3. A third cause of failure is when a metal screwdriver tip slips or a screw drops onto the board while it is powered on causing a short between a power pin and a signal pin on a component This can cause overvoltage power supply problems described below To avoid this type of failure only perform assembly operations when the system is powered off Sometimes boards are stored in racks with slots that grip the edge of the board This is a common practice for board manufacturers However our boards are generally very dense and if the board has components very close to the board edge they can be damaged or even knocked off the board when the board tilts back in the rack Diamond recommends that all our boards be stored only in individual ESD safe packaging If multiple boards are stored together they should be contained in bins with dividers between boards Do not pile boards on top of each other or cram too many boards into a small location This can cause damage to connector pins or fragile components Power supply wired backwards Our power supplies and boards are not designed to withstand a reverse power supply connection This will destroy each IC that is connected to the power supply In this case the board will most likely will be unrepairable and must be replaced A chip destroyed by reverse power or by excessive power will often have a visible hole on the top or show some deformation on the top surface due to vaporization inside the package
