What constitutes a 'major defect' in the context of IPC-A-610?

In the context of IPC-A-610, a 'major defect' is defined as a nonconformance that significantly impacts the functionality, safety, or performance of the electronic assembly. This classification highlights the critical nature of certain defects that can lead to failure or safety concerns in the end product. For instance, if a component is improperly seated or soldered in a way that affects electrical connectivity, this would be deemed a major defect because it can lead to circuit failure or unexpected behavior during operation.

The focus on functionality, safety, and performance underscores the importance of adhering to established quality standards within electronic manufacturing. This is essential to ensure that products meet the rigorous demands of performance and safety that they are designed for. Because a major defect can compromise the integrity of the entire assembly, it requires immediate attention and rectification to avoid any hazardous consequences or loss of reliability in the product's use.

In contrast, other options describe issues that fall outside the criteria for major defects—such as minor visual blemishes or defects that do not impact performance. These generally do not compromise the assembly's core functionalities or safety, thus they may be categorized as minor or insignificant. Issues that are easily fixable may also not signify a major defect because they indicate that remediation can be performed
