Process FlowKorea Circuit is at the center of the smart world.
Inspection
Process to check the product exterior and quality characteristics using visions and magnifiers
- Final inspection
- This is a 100% test. Mainly, the quality of the exterior is checked visually, or by AFI(Automatic Final inspection) or magnifiers.
- Outgoing/reliability inspection
- Exterior dimensions, hole sizes, and product thickness are tested. Shipping report is prepared.
