How should the technician handle the PCBs while dismantling or repackaging them?

The best handling technique for printed circuit boards (PCBs) during dismantling or repackaging is from the edges or sides. This method is crucial because PCBs are sensitive to electrostatic discharge (ESD) and physical damage. Touching them by the edges minimizes the risk of shorting out circuits or damaging components.

Holding PCBs by the center can be risky, as it moves your fingers closer to the sensitive components and traces, increasing the chance of physical damage. Furthermore, using gloves may introduce risks if they are not ESD-safe gloves, and while working in a static-free environment is optimal to prevent ESD damage, it does not address the physical handling of the PCBs. Therefore, handling them from the edges or sides is the most effective way to ensure their safety and integrity.
