To prevent CPU pins from being bent or damaged, which items must technicians ensure are in use when repackaging?

The use of an ESD (Electrostatic Discharge) bag and a ZIF (Zero Insertion Force) Socket T cover is essential in protecting delicate CPU pins during repackaging. ESD bags are designed to prevent static electricity buildup that could potentially damage sensitive electronic components. By using an ESD bag, technicians ensure that any sensitive electronic parts are shielded from electrostatic discharges, which could result in component failure.

Additionally, the ZIF Socket T cover provides physical protection specifically for the CPU pins. This cover helps to keep the pins aligned and secured, significantly reducing the risk of bending or damage during handling or transport. This dual-layer of protection—against both static electricity and physical damage—makes the combination of an ESD bag and a ZIF Socket T cover the most appropriate choice.

The other options, while useful in various contexts, do not specifically address the need for electrostatic protection and the physical safeguarding of CPU pins. For example, plastic wrapping and zip ties may not provide adequate protection against static or physical impact, while bubble wrap and a corrugated box, though helpful for cushioning, do not mitigate the risk from static electricity. Similarly, cardboard and tape lack the specialized properties required for safeguarding electronic components effectively.
