What does ESD stand for in the context of Mac repair, and why is it a concern?
Answer: Electrostatic Discharge; can permanently damage sensitive electronic components with static electricity
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.
Which item is most important for a technician to wear when working on internal Mac components to prevent ESD?
Answer: An anti-static wrist strap connected to an ESD mat or ground point
An anti-static wrist strap bonded to a grounded surface continuously dissipates static charge from the technician's body, preventing ESD damage to components.
What is the purpose of an ESD mat on a repair workstation?
Answer: To provide a grounded static-dissipative surface that prevents ESD buildup and safely channels static to ground
An ESD mat provides a controlled, grounded surface that dissipates static electricity, protecting components placed on it from electrostatic discharge.
Before opening a MacBook for repair, what should the technician do to reduce ESD risk?
Answer: Touch the metal chassis of the Mac (when unplugged) to equalize potential, and use an ESD wrist strap throughout
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.
Which type of screwdriver is most commonly used for internal screws on MacBook logic boards and components?
Answer: Torx T3 or T5
Internal MacBook screws securing components to the logic board commonly use Torx T3 or T5 heads, requiring the appropriate Torx driver to avoid stripping.
What is the risk of using a magnetized screwdriver near an SSD or logic board during Mac repair?
Answer: Magnetic fields can corrupt data on magnetic storage; while SSDs are less vulnerable, magnets near certain sensors or components can cause issues
While SSDs are generally not affected by magnets (unlike HDDs), strong magnetic fields near sensors, speakers, or other components can still cause issues; using demagnetized tools near critical components is safest practice.
