For the verification of yellowing resistance of electronic connectors, it is necessary to focus on verifying the yellowing resistance of materials and stability of electrical performance in ultraviolet (UV), high temperature, humidity and heat, etc. It is suitable for reliability testing of connectors in the fields of automobiles, consumer electronics and industrial equipment. The following are the technical points and verification program:
1. Principle of yellowing-resistant aging test
Aging mechanism:
Light aging: ultraviolet light (wavelength 290-400 nm) triggered polymer materials (such as PA, PBT, PC) chain breakage, resulting in surface yellowing.
Heat aging: High temperature (>85C) accelerates the oxidation reaction, prompting plasticizer volatilization or material crystallization.
Moist heat aging: moisture penetration leading to material hydrolysis (e.g. PET) or interfacial corrosion (metal terminals).
Test Objective:
Verify the color stability (E 1.5) of connector housings and insulators in long-term use.
Ensure that electrical properties such as contact resistance, insulation resistance, etc. comply with standards (e.g. IEC 60512).
2. Test equipment and conditions
(1) Core equipment
UV aging tester:
Light source: UVA-340 (simulated solar spectrum) or UVB-313 (accelerated aging).
Irradiation intensity: 0.5-1.5 W/m/nm @340 nm (adjustable).
Constant Temperature and Humidity Chamber:
Temperature range: -40C ~ +150C, Humidity: 10%-98% RH.
Colorimeter:
Measurement parameters: CIE Lab E value (accuracy 0.05), quantifying the degree of yellowing.
(2) Test conditions (example)
Test Type Condition Parameter Standard Basis
UV aging 60C, UVB-313 light 8h + condensation 4h, cycle 1000h ASTM G154
High temperature aging 125C, 1000h IEC 60068-2-2
Damp heat aging 85C/85% RH, 1000h IEC 60068-2-78
3. Test procedure and evaluation method
Pretreatment:
Samples are equilibrated in a standard environment (23C, 50% RH) for 24 hours.
Initial performance test:
Color measurement: Initial Lab* values are recorded using a colorimeter.
Electrical test: contact resistance (20 m), insulation resistance (100 M).
Aging test:
Accelerated aging under preset conditions (e.g. UV + high temperature cycle).
Mid-term testing:
Take samples every 250h, observe surface cracks and deformation, and record E value.
End point evaluation:
Appearance inspection: visually compare the color cards (e.g. Pantone color number) and confirm that there is no significant yellowing.
Electrical performance: contact resistance change rate 10%, insulation resistance 10 M.
Mechanical properties: Plugging and unplugging force attenuation 15% (refer to EIA-364-13 standard).
4. Key influencing factors and material optimization
Material selection:
Anti-UV additives: add benzotriazole light stabilizers (e.g. Tinuvin 326).
Heat-resistant resin: Select LCP (liquid crystal polymer) or PPS (polyphenylene sulfide).
Process improvement:
Control mold temperature during injection molding (e.g. PBT needs 80-100C) to reduce yellowing caused by internal stress.
Optimization of metal terminal plating (e.g. gold/tin plating, thickness 0.5 m).
5. Test standards and industry norms
International Standard:
IEC 60512-11-14: Environmental test methods for connectors (including weathering test).
ISO 4892-3: Laboratory light source exposure test for plastics (Xenon/UV lamp).
Industry Specification:
Automotive electronics: USCAR-2 (high temperature durability), LV214 (hot and humid aging).
Consumer Electronics: Apple MFi certification (color stability requirements).

FAQ's of Verification of resistance to yellowing and aging of electronic connectors:
Q: How does the Yellowing & Aging Resistance Testing Machine verify resistance to yellowing and aging in electronic connectors?
A: The equipment exposes electronic connectors to accelerated environmental stress using UV and Xenon lamps, programmable cycles, controlled temperature (up to 300C), and adjustable humidity (20%-98%RH). Using its integrated spectrophotometer, it measures changes in color (yellowing index) over time, providing precise, real-time results.Q: What is the process for conducting a test using this machine?
A: Testing involves placing 1-12 electronic connector specimens in the chamber, programming the desired test parameters via the touchscreen, and initiating the cycle. The chamber then automatically manages exposure, temperature, and humidity while real-time data are logged internally and can be exported via USB for analysis.Q: When should I use this testing machine for electronic connectors?
A: Use this testing machine during quality control at various production stages or during product development when you need to assess long-term reliability and compliance with standards such as IEC, ASTM, or UL. It is suitable for both routine laboratory analysis and industrial verification.Q: Where can the testing machine be installed and operated efficiently?
A: This floor-standing machine is optimized for laboratory and industrial quality control settings. It requires an AC 220V power supply in an environment with temperatures from 0-40C and humidity up to 85% RH, ensuring operational stability within standard indoor conditions.Q: What are the benefits of using a programmable timer and automatic logging system in this equipment?
A: A programmable timer (up to 9999 minutes) and automatic logging promote precise control over test duration and ensure detailed, error-free documentation of every test. This reduces manual intervention, increases consistency in results, and greatly simplifies data management and result retrieval.Q: How is safety managed during the testing process?
A: The system incorporates overload, over-temperature, and leakage protection mechanisms to protect both users and specimens during testing. These automated safeguards monitor operational conditions and intervene if anomalies are detected, maintaining a safe environment throughout each cycle.Q: What are the advantages of integrated data storage and PC analysis software?
A: Internal memory and USB export allow direct retrieval of test results, facilitating analysis and record-keeping. The included PC software further enables comprehensive data review, trend analysis, and reporting, assisting in compliance, audits, and continuous quality improvement efforts.Tell us about your requirement
