    Why do pcb's (nic's and power supply's) blow?

    Has anyone got some sort of letter or formal discription of why a certain pcb will blow or pop etc. (esd, power dips,spikes or lightning)
    We need to give it to customers for insurance claims etc.
    Thanks guys!

      Any particular machine? if you're talking about Ricoh MPC4500 there is a tech bulletin about a component blowing on the power supply board. attached is the appropriate Tech bulletin

          If it is the MPC3500/MPC4500, I'm sure the insurance company will be delighted to know the damage is caused by the machine not being operated correctly
