ACMT Tools, Safety & ESD Procedures

Question 1

What does ESD stand for in the context of Mac repair, and why is it a concern?

Accepted Answer

Electrostatic Discharge; can permanently damage sensitive electronic components with static electricity

Answer

Electrostatic Discharge is the sudden flow of static electricity between objects, which can permanently damage logic board components, RAM, and other sensitive parts during repair.

Question 2

Which item is most important for a technician to wear when working on internal Mac components to prevent ESD?

Accepted Answer

An anti-static wrist strap connected to an ESD mat or ground point

Answer

An anti-static wrist strap bonded to a grounded surface continuously dissipates static charge from the technician's body, preventing ESD damage to components.

Question 3

What is the purpose of an ESD mat on a repair workstation?

Accepted Answer

To provide a grounded static-dissipative surface that prevents ESD buildup and safely channels static to ground

Answer

An ESD mat provides a controlled, grounded surface that dissipates static electricity, protecting components placed on it from electrostatic discharge.

Question 4

Before opening a MacBook for repair, what should the technician do to reduce ESD risk?

Accepted Answer

Touch the metal chassis of the Mac (when unplugged) to equalize potential, and use an ESD wrist strap throughout

Answer

Touching the unplugged Mac's metal case equalizes the technician's static potential with the device, and wearing an ESD wrist strap throughout the repair maintains that protection.

Question 5

Which type of screwdriver is most commonly used for internal screws on MacBook logic boards and components?

Accepted Answer

Torx T3 or T5

Answer

Internal MacBook screws securing components to the logic board commonly use Torx T3 or T5 heads, requiring the appropriate Torx driver to avoid stripping.
