Technician Tommy is replacing a logic board on a Mac mini. Which of the following should he hold when handling the logic board?

Question

Options

• AAny components
• BThe heat sinks
• CThe connectors
• DThe edges of the logic board

• A
  5% (2)
• B
  3% (1)
• C
  3% (1)
• D
  90% (35)

Explanation

Holding the edges of the logic board minimizes contact with sensitive components and reduces the risk of electrostatic discharge (ESD) damage or physical damage to circuitry and solder points.

Why the distractors are wrong:

• A (Any components): Touching random components risks bending pins, dislodging chips, or transferring oils and static to sensitive circuitry.
• B (Heat sinks): Heat sinks are attached to components and applying pressure to them can stress the underlying chips or break thermal paste seals.
• C (Connectors): Connectors are fragile and easily bent or contaminated - gripping them risks damage and poor connections after reassembly.

Memory tip: Think of a logic board like a photograph - you always hold a photo by its edges to avoid smudging or damaging the surface. Same principle applies here: edges only, nothing in the middle.
