When replacing a DIP chip, which safety measure is recommended?

• A. A static-damped wrist strap
• B. A grounded metal workstation
• C. Anti-static gloves
• D. An ESD static grounded pencil and work station

Answer: (D)

Electrostatic discharge control is essential when handling DIP chips because these sensitive components can be damaged by very small charges. The safest approach is to keep everything involved at earth potential by providing a continuous grounding path for charges. An ESD-grounded pencil and a grounded work station achieve this by giving a constant, low-impedance return path to earth for charges on the tool, the chip, and the board. With the tool and surface both grounded, any static built up during manipulation can flow away smoothly, dramatically reducing the risk of a damaging discharge as you install or remove the DIP. This combination works better than other individual measures because a wrist strap helps, but only if it’s correctly used and remains the sole grounding path; if it’s forgotten or misused, charges can still accumulate. Anti-static gloves reduce contamination but don’t guarantee a reliable discharge path. A grounded workstation helps, but without grounded tools, charges can still transfer through the component. Using a grounded pencil together with a grounded work surface provides a consistent, complete grounding setup for reliable protection.
