Before using shielding bags, which test is mandatory?

• A. Electrical resistance test
• B. Visual inspection
• C. Tensile strength test
• D. Temperature stability test

Answer: (B)

Using shielding bags effectively is crucial for protecting sensitive electronic components from damage due to electrostatic discharge (ESD). The mandatory test prior to using these bags is a visual inspection. This step is fundamental to ensure that the bags are free from any physical damage, such as tears, punctures, or other types of degradation that could compromise their shielding effectiveness. A visual inspection allows personnel to verify the integrity of the shielding bags, confirming that they are in proper condition before storage or transport of ESD-sensitive devices. If the bags are compromised in any way, they may not provide adequate protection, leading to potential failures or damage to the components they are intended to shield. While other tests like electrical resistance or tensile strength might be relevant in assessing different properties or factors of materials and containers, the immediate visual inspection is the first line of defense in ensuring operational safety and reliability.
