In the connector industry, material quality control is a core factor that determines product performance, reliability, and lifespan. Especially in high-demand fields such as radio frequency, automotive, and industrial automation, connectors must not only ensure stable electrical performance but also possess durability and environmental friendliness in complex environments. This article will analyze the key points and trends in material quality control standards for domestic connectors in combination with the practical experience of IMS Connector Systems.
One, the quality concept of IMS Connector SystemsAs an international manufacturer focusing on high-frequency and radio frequency connection technologies, IMS Connector Systems has been serving high-reliability application fields such as communication, automotive, and industrial for a long time. The brand has production and R&D bases in China and has obtained multiple system certifications including ISO 9001 and ISO 14001, ensuring that materials and production processes meet international standards.
Their products, such as the SnapN Quick Lock series, 4.3-10 High-Frequency Interface, and the SMBA®/FAKRA series for automotive use, all have extremely high requirements for materials:
●High conductivity metal (such as gold-plated or silver-plated contacts), to ensure low contact resistance;
High-temperature resistant, flame-retardant plastic, meets the standards of automotive and industrial environments.
● Eco-friendly compliant materials, meeting international environmental regulations such as RoHS, REACH, etc.
This provides a valuable reference case for the material quality control of domestic connectors.
Second, the key points of quality control for domestic connector materialsConductivity material control standards
●The contact part should be made of high-purity copper alloy and undergo surface coating (such as gold plating, nickel plating) to ensure conductivity and anti-oxidation properties.
● Contact resistance should be maintained at a very low level to avoid signal attenuation due to poor material.
Insulation and shell materials
●Common engineering plastics such as PBT, LCP, PA66, need to meet high temperature, flame retardant (UL94 V-0), and moisture resistance properties.
In automotive and outdoor applications, it is necessary to undergo salt spray testing and cold-heat cycle testing to verify long-term environmental adaptability.
Environmental protection compliance
● Complies with RoHS, REACH standards, ensuring lead-free, halogen-free, and free of harmful heavy metals.
In the process of domestic substitution, environmental and regulatory compliance is an important prerequisite for gaining customer trust.
Batch traceability and detection
Each batch of materials must have a test report and batch traceability.
●Ensure material stability in the supply chain through XRF spectral analysis and mechanical property testing.
Three, insights for domestic substitution from the experience of IMSDomestic connectors should fully refer to IMS's standardized process in material control:
Establish a materials access list based on the international certification system.
Strengthen cooperation with local material suppliers to ensure the balance between localization and compliance.
●Through strict laboratory testing, achieve a closed-loop quality control;
Under the increasingly strict environmental protection regulations, it is advisable to plan for green materials in advance.
This will help domestic brands gradually enhance their market competitiveness and accelerate the pace of domestic substitution.
Domestic connector manufacturers must establish a sound standard system in material quality control to achieve stable substitution. From the conductive contacts to the insulating shell, from environmental protection regulations to the full-process traceability, only by controlling every link can we ensure that domestic products can compete on the same stage with international brands in the high-reliability field.
