Which of the following may be damaged or destroyed by electrostatic discharge?

Electrostatic discharge (ESD) can lead to significant damage or destruction of electronic components, particularly sensitive devices. Both printed circuit boards (PCBs) and solid-state devices are susceptible to the effects of ESD.

Printed circuit boards often contain delicate components and intricate circuits that can be disrupted by the high voltages associated with electrostatic discharge. A sudden discharge can lead to malfunction or catastrophic failure of these components.

Solid-state devices, which include transistors, integrated circuits, and diodes, are particularly vulnerable as they operate at very low voltages and currents. The sensitive nature of their internal structures means that even minor static charges can cause permanent damage, degradation of performance, or complete failure.

As such, both printed circuit boards and solid-state devices are at risk, making the option that states "Both printed circuit boards and solid-state devices" the correct choice. Recognizing this potential vulnerability is essential for proper handling and protection measures in electronic work environments.
