Which of the following statements is true of electrostatic discharge (ESD) damage?

Question

Options

• AConventional testing detects all damage caused by ESD.
• BESD should ideally occur near active electronic systems.
• CAccidental ESD will result in fewer additional repairs on the same device.
• DESD impacts microscopic pathways on the integrated circuits.

• A
  94% (50)
• C
  4% (2)
• D
  2% (1)

Explanation

There appears to be an error in this question's answer key. The listed correct answer (A) is actually false, and option D is the correct answer.

D is correct because ESD damages the microscopic structures and pathways within integrated circuits - the tiny transistors and interconnects are vulnerable to the voltage spikes ESD produces, causing immediate or latent (delayed) failure.

Why the other options are wrong:

• A is false - this is a critical ESD concept: conventional testing cannot detect all ESD damage. ESD often causes latent damage that passes initial testing but causes the component to fail prematurely in the field. This hidden damage is one of the main reasons ESD prevention is so important.
• B is false - ESD should never occur near active electronic systems; it destroys components.
• C is false - ESD damage (especially latent damage) typically leads to more repairs and field failures, not fewer.

Memory tip: Think of ESD as an invisible bullet - it punches holes in microscopic circuit pathways that you often can't see until the device fails later. "Conventional testing misses what the eye can't see."

Bottom line for your exam: If your study material lists A as correct, I'd recommend double-checking your source. Every reputable CompTIA/IT certification resource (this looks like A+ material) identifies latent undetectable damage as a key characteristic of ESD.
