Quality Commitment
Excellence in Every Connection, Zero-Defect Delivery
At Yiou Guan Optotech Co., Ltd., quality is more than just a department; it is our unwavering promise to our global partners. We recognize that every wire harness and terminal is critical to system safety, which is why quality control is deeply embedded in our corporate DNA.
Our Three Pillars of Assurance
Precision Technology & Standards Following IATF 16949 automotive-grade logic to ensure material integrity from the very start.
Data-Driven Process Implementing Tensile Testing and monitoring with a strict Line Stop Mechanism to prevent defects from moving downstream.
100% Confidence in Delivery Every product undergoes 100% Electrical Testing and full traceability verification before it leaves our facility.
Our Philosophy: The Five "Mosts"
We are committed to providing: The Most Exquisite Technology, Reasonable Management, Accurate Delivery, Excellent Quality, and Satisfactory Service.
Total Quality Management (TQM) System
01
Incoming Quality Control (IQC)Material Integrity
100% Genuine Spec Verification Rigorous visual and dimensional inspections for all incoming wires, terminals, and connectors to ensure 100% compliance with original manufacturer specifications.
Conductor & Insulation Inspection Utilizing high-precision calipers and microscopic equipment to measure outer diameter (OD), wall thickness, and conductor structure.
Critical Data Monitoring Strict monitoring of terminal insertion/extraction force to prevent substandard raw materials from reaching the line.
02
In-Process Quality Control (IPQC)Precision Process Control
Parameter Lock-down Standardized First-Middle-Last (FML) inspections and periodic patrols for automated cutting, stripping, and soldering processes.
Crimping Excellence Utilizing Tensile Testers to monitor terminal crimp strength while verifying exposed wire cores and insulation crimp height.
Line Stop Protocol Implementation of a robust Line Stop Mechanism (Reaction Plan): production halts immediately upon detecting any functional or dimensional deviation.
03
Final Quality Control (FQC)Zero-Defect Delivery
100% Electrical Testing Mandatory 100% Electrical Testing before shipment to guarantee zero short circuits and correct housing/terminal alignment.
Functional Validation Airtightness and installation verification for seals and dummy plugs to ensure ingress protection standards are met.
Full Traceability Comprehensive inspection sheets and packaging labels for every batch, ensuring full traceability aligned with automotive PPAP requirements.
