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.
