Study Notes
Criteria for Abnormal Level Judgement
- Abnormal levels of judgement are assessed through visual critical and non-critical defects.
Visual Critical Defects
- Defined defects that significantly impact functionality include:
- Missing parts which can lead to incomplete assemblies.
- Incorrect orientation that may cause operational failures.
- Reverse polarity, affecting electrical connections.
- Cold solder joints, which can lead to unreliable connections.
- Delamination that compromises structural integrity.
- Wrong components being used, leading to malfunctions.
- Scattered components indicating improper placement.
- Cracked solder joints, resulting in potential electrical failure.
- Burned components indicating overheating or electrical malfunction.
Visual Non-Critical Defects
- Non-critical defects require monitoring and include:
- Presence of 5 identical defects in the same location within one hour.
- Accumulation of 6 cumulative defects in the same location over consecutive hours, indicating a pattern that may need intervention.
Action Plan
- Operators are responsible for immediately notifying the group leader or production person in charge (PIC) when abnormalities are encountered to ensure timely resolution and maintain production quality.
Abnormal Level Judgement Criteria
-
Visual Critical Defects are serious issues that impact functionality:
- Missing part: A component is absent from the assembly.
- Wrong orientation: Components installed incorrectly, affecting performance.
- Reverse polarity: Incorrect wiring that can lead to malfunction or damage.
- Cold solder: Poor solder joints that do not establish a proper electrical connection.
- Delamination: Separation of material layers that can compromise structural integrity.
- Wrong component: Incorrect part used in the assembly process.
- Scattered defects: Multiple defects in various locations impacting reliability.
- Crack solder: Fractured solder connections that may lead to failures.
- Burn component: Components showing signs of overheating or damage.
Visual Non-Critical Defects
- These defects are less severe but still require attention:
- Duplicate defects: Identifying five identical defects in the same location within one hour prompts scrutiny.
- Cumulative defects: Noticing six or more defects at the same location over consecutive hours raises a concern for quality control.
Action Plan for Handling Abnormalities
- Operator's Responsibility: Should promptly alert the group leader or production PIC (person in charge) upon encountering any abnormalities to ensure swift resolution.
