Which of the following is an ESD precaution that must be taken when working with Apple devices?

Question

Options

• AUse polyester foam mats to ground the workbench.
• BDo not place internal components on metal surfaces.
• CPick up circuit boards using their connectors.
• DWhen handling internal components, wear synthetic materials.

• B
  92% (23)
• C
  4% (1)
• D
  4% (1)

Explanation

Placing internal components on metal surfaces creates a path for electrostatic discharge, potentially damaging sensitive electronics - keeping them on non-conductive, anti-static surfaces (like an ESD mat) is standard ESD protocol when servicing Apple devices.

Why the distractors are wrong:

• A - Polyester is a synthetic material that generates static electricity; ESD mats must be made of anti-static or conductive rubber, not polyester foam.
• C - Picking up circuit boards by their connectors is a mechanical damage risk and can also transfer static directly to the most sensitive contact points; always handle boards by the edges.
• D - Synthetic materials (polyester, nylon) are notorious for building up static charge - technicians should wear natural fibers (cotton) or use an anti-static wrist strap grounded to the chassis.

Memory tip: Think "ESD = Everything Static Dies" - anything that generates static (polyester, synthetics, metal surfaces without grounding) is the enemy. The safe rule is: non-conductive, anti-static surfaces + natural fibers + wrist strap = safe handling.
