Power Bank In-Process Quality Control (IPQC) Checklist
Keep the released product state under control while units are being built. Use IPQC to verify first-piece approval, line setup, firmware, assembly, patrol checks, rework and traceability.
In-Process Quality Control — 4 Practical Checks
Record the exact SKU, production lot, released revision, station owner, result and disposition. Use project-specific process limits and released work instructions.
Best for: confirming the line starts from the released product state.
Model / SKU / production lot: ___
BOM / PCBA / firmware: ___
Approved material lots: ___
Fixture / equipment setup: ___
First-piece fit / charge / function: ___
Decision: Continue / Recheck / Hold
Best for: controlling firmware, cable, soldering and assembly inputs.
Programming version: ___
Cell / PACK polarity & insulation: ___
Cable / connector revision: ___
Solder / weld / flex route: ___
Torque / adhesive / cure state: ___
Decision: Continue / Correct / Hold
Best for: detecting drift after first-piece approval.
Power-on / I-O charging: ___
PD / PPS / cable / mechanism: ___
Protection indicators: ___
Gap / flushness / alignment: ___
Cosmetic / patrol trend: ___
Decision: Continue / Stop / Recheck
Best for: controlling defects before more units are affected.
Defect / NCR ID: ___
Affected quantity / time window: ___
Stop / hold / segregation: ___
Approved rework / re-inspection: ___
Lot / station traceability: ___
Release: Restart / Conditional / Hold
Rule: IPQC must verify both the product and the process. If setup, firmware, material, tooling or work instructions drift from the released state, stop, contain and correct before continuing production.
IPQC Line Decision & Next Control
First piece is approved and the released process remains stable.
WI, fixture, firmware, material or setup no longer matches the released state.
A defect trend or yield drop appears; bound affected units before restart.
The issue repeats, escapes correction or shows the existing control is ineffective.
