In this appendix, the focus is on electrostatic shielding. Several electrostatic effects can in fact damage or cause failure in electronic components and assemblies. High- speed and high-density electronic devices are especially vulnerable because of their high static sensitivity. In general, the presence of even a single very static sensitive device on a printed-circuit board requires that the entire assembly be handled with static protective precaution. The most typical example of electrostatic damage consists o…
