Power Bank Incoming Quality Control (IQC) Checklist
Stop the wrong material before it reaches assembly. Verify incoming lots against the released BOM, approved source, revision and traceability requirements.
Incoming Quality Control — 4 Practical Checks
For each lot, record supplier, lot/date code, released requirement, result and disposition. Critical parts must remain traceable to the approved BOM and source.
Best for: preventing wrong or unapproved material from entering the line.
Supplier / PO / lot: ___
Part number / revision: ___
Approved source / alternate: ___
Received / sampled quantity: ___
BOM / drawing match: ___
Decision: Pass / Hold / Recheck
Best for: controlling the parts that drive safety and electrical performance.
Cell / PACK model & lot: ___
OCV / IR / Wh evidence: ___
PCBA / firmware revision: ___
Critical IC / MOSFET / inductor: ___
Solder / contamination / function: ___
Decision: Pass / Hold / Reject
Best for: catching fit, cosmetic, connector and packaging mismatch before assembly.
Cable / connector revision: ___
Continuity / retention: ___
Housing / color / dimensions: ___
Mechanism / magnet / coil state: ___
Label / artwork / pack contents: ___
Decision: Pass / Sort / Hold
Best for: deciding what happens when incoming material does not match the released state.
NCR / issue ID: ___
Hold / reject / sort / return: ___
Supplier response / CAPA: ___
Released quantity: ___
Inspector / date: ___
Release: Pass / Conditional / Reject
Rule: IQC confirms the material received matches the released requirement. It does not approve an unreviewed supplier substitution, mixed lot or engineering change.
IQC Release Decision & Next Control
Part, source, revision and critical criteria are verified and traceability is recorded.
Identity, source approval or revision is unclear. Do not issue the lot to production.
Acceptance criteria fail or defects repeat. Segregate the lot and trigger supplier action.
A substitution or mixed lot needs engineering / quality approval before use.
