When components are mounted on a board, what is a common misconception about their ESD susceptibility?

• A. They are totally safe from ESD
• B. They become more susceptible to ESD
• C. They are less susceptible to ESD
• D. They only need ESD protection during shipping

Answer: (C)

The belief that mounted components are less susceptible to electrostatic discharge (ESD) is a common misconception. When components are mounted on a circuit board, one might think that being enclosed and connected to ground or other components would automatically reduce their vulnerability to ESD events. However, this is not the case. While some shielding effects can occur due to the structure of the board and grounding techniques, it does not eliminate the risk entirely. In fact, once components are installed, they can still be exposed to ESD during handling, soldering, and testing. The risks of ESD damage can still be present due to the potential for accidental discharge from handlers or from other electronic components in close proximity. Therefore, recognizing that mounted components still require careful ESD protection protocols is essential for maintaining their integrity and reliability.
