Every harness follows the same documented process. See the ten-stage QC plan behind it.
QC1T-W-PG-010 · REV. B0
Ten controlled stages, on record.
Behind the seven processes sits our QC control plan — from incoming inspection to finished-goods storage, each stage with its frequency, method and record.
01MATERIAL / IQC
Incoming inspection
Check purchased materials against engineering data, inspection specs and the supplier outgoing report.
02MATERIAL / CONTROL
Material storage & issue
Storage: stock card, location label and protection. Issue: match name, part number and quantity to the work order.
03PROCESS / DIMENSIONS
Cutting & stripping
Verify wire spec, cut length and strip dimensions; check conductors for damage or broken strands.
04PROCESS / CRIMP
Terminal crimping
Check terminal spec, crimp appearance and retention force to the drawing and work instructions.
05PROCESS / CHECK
In-process inspection
Inspect terminal specification and crimp appearance with a magnifier.
06ASSEMBLY / POSITION
Housing assembly
Insert terminals into the housing; confirm wire order, wire positions and terminal seating.
07ASSEMBLY / PROTECTION
Sleeving & heat shrinking
Fit the specified sleeve and shrink it in place without heat damage.
08FINAL / INSPECTION
Electrical & visual inspection
Run continuity test to the required parameters, then visual inspection.
09DELIVERY / RELEASE
Packing & outgoing sampling
Confirm packing method, then sample finished goods to specs, drawings and customer requirements.
10DELIVERY / STORAGE
Finished-goods storage
Store accepted finished goods with matching stock records, correct location labels and protection.
