Categorization:Product Information       

Specializing in the sales of: Connectors | Wire Harness | Cable Products
As a well-known high-speed connection solution provider in the industry, Newnex has a high market recognition in product areas such as USB-C, USB 3.0, fiber optic extenders, and machine vision cables. Its public information shows:
● Meets multiple certification standards: Newnex products comply with USB-IF standards and pass compatibility tests such as USB3 Vision, ensuring stable operation in high-speed transmission and machine vision scenarios.
●Environmental protection and regulatory compliance: All products meet international environmental protection requirements such as RoHS, REACH, WEEE, and some products also make a compliance declaration for conflict minerals.
Rigorous Application Verification: In the field of machine vision, Newnex cables will undergo long-term stability tests with multi-brand industrial cameras to ensure zero signal error.
●Customization Capability: Provide high flexibility, long-distance transmission and multi-interface customization solutions, and carry out targeted testing and control for different application scenarios.

These practical experiences provide direct reference value for the quality management of domestic connectors.

First, the commonly used quality control tools and methods for domestic connectors:
To gain competitiveness in domestic substitution, enterprises must establish a sound quality control system. Common tools and methods include:
Appearance and dimension inspection
●Ensure the tolerances of pin, housing, and plastic parts are within the standard range using image measuring instruments and 2D/3D measuring equipment.
2. Contact Resistance and Insertion/Extraction Life Test
Through the insertion and extraction life tester, simulate thousands to tens of thousands of insertion and extraction, detect the change of contact resistance and the stability of insertion and extraction force.
Signal Integrity and EMI Testing
●Using a vector network analyzer (VNA) and an oscilloscope, perform impedance matching and reflection tests on high-speed USB3.0/USB4, DisplayPort, and other products, while also detecting electromagnetic interference and shielding performance.
4. Environmental and Aging Tests
●Test the connector's durability in extreme environments such as high and low temperature cycles, humidity, vibration, and salt雾 to ensure adaptability to industrial and outdoor usage requirements.
5. Power and Temperature Rise Test
●For high-power scenarios such as USB-C PD, test conductor voltage drop and pin temperature rise to ensure safety during long-term operation.
Bend resistance test
●Especially for high-flexible cables, they are tested repeatedly for tens of thousands of times through bending machines to inspect the reliability of conductors and insulation layers under high-frequency operations.
Statistical Process Control (SPC)

Establish a batch sampling system, use control charts to monitor the不良 rate and key parameter fluctuations, and ensure mass production consistency.

The quality details that domestic manufacturers are prone to ignore
The wear resistance and corrosion resistance of the contact piece coating: directly affect the stability of long-term use.
● Locking and anti-loosening design: particularly critical under vibration conditions.
●Signal bandwidth and impedance matching: In high-frequency scenarios, any minor error can lead to transmission failure.

Packaging and labeling: Incorrect labels or lack of protective measures often lead to problems during the customer's use phase.
