What is the essential practice for handling printed circuit boards?

Always remove power when installing or removing boards
Keep boards in a humid environment
Use maximum force when inserting into slots
Handle without any form of gloves

The correct answer is: Always remove power when installing or removing boards

The essential practice for handling printed circuit boards is to always remove power when installing or removing boards. This is critical because it helps prevent electrical shock, which can be dangerous for the technician, and it also protects the circuit board itself from potential damage due to static electricity or short circuits. When power is removed, there is no risk of electrical current causing unexpected behavior or damage during handling. Additionally, keeping boards in a humid environment, using maximum force when inserting boards into slots, and handling without any form of gloves can all lead to various issues such as moisture damage, physical damage to the components, or contamination. Therefore, the practice of removing power contributes to safety and longevity of the electronic components, making it the correct choice in this scenario.
