Q

What path does the I/O shield use to protect the chip from ESD

A
  1. Pins in the I/O shield connect to
  2. The external metal parts of the ports to the metal case which is in turn
  3. Bonded to the PSU, chich connects to
  4. The building’s ground system when plugged in. Which provides a safe path for ESD to drain into instead of arcing to a chip.
