In the trend of automotive electronics, intelligent driving, and electrification, the performance of connectors directly determines the safety and reliability of the entire vehicle. As an important brand in the automotive connector field, Raydiall Automotive has long focused on providing high-performance connection solutions for automotive manufacturers and first-tier suppliers. Its products cover Fakra / HFR3C high-frequency connectors, PCB connectors, and electric vehicle charging interfaces, and are widely used in vehicle antennas, cameras, V2X communications, and electric vehicle charging systems.
Raydiall's core strengths lie not only in products that meet automotive industry standards such as ISO 20860 and USCAR-17, but also in its experience in high-frequency signal integrity, waterproof sealing structures, and automated assembly processes, all of which provide valuable references for domestic connectors in material selection and performance comparison.
The core experience in material selection for domestic connectorsIn the process of replacing international brands such as Raydiall with domestic products, material selection is a key factor in determining performance and reliability. The following points are particularly important:
Conductor material selection
Raydiall commonly uses high-purity copper alloys, supplemented by gold and silver plating processes, to ensure low signal transmission loss and corrosion resistance.
When choosing domestic alternatives, high-conductivity copper alloys with good stress relaxation resistance should be prioritized, while ensuring the coating thickness and uniformity.
Insulators and sheath materials
●International brands often use engineering plastics such as PBT, LCP, and PA66, which have characteristics of flame retardancy, high temperature resistance, and resistance to moisture and heat.
●Attention should be paid to the flame retardant grade (UL94 V-0), weather resistance and UV protection when replacing domestic solutions, to avoid performance degradation in high temperature or outdoor environments.
Surface Treatment and Coating
The durability of the coating is directly related to contact resistance and signal integrity. Raydiall has a mature solution in the nickel + gold plating process.
Domestic manufacturers should strictly control the electroplating process to ensure the thickness and adhesion of the coating, and verify it through salt spray and humidity test.
Sealing and protective materials
Dust, rain, and vibration are inevitable in the automotive environment, and Raydiall's multi-range connectors have reached the IP67/IP69K protection level.
●Domestic substitution requires careful selection of sealing ring and rubber ring materials to ensure long-term aging resistance, while also considering ease of assembly.
5. Signal Integrity Material Control
High-frequency connectors require low dielectric constant and low-loss plastic materials to reduce insertion loss and return loss.
●Domestic manufacturers should focus on dielectric property data during material selection and perform RF S parameter verification.
Raydiall Automotive's technical accumulation in the automotive connector field provides a benchmark for domestic substitution. To truly achieve substitution, domestic manufacturers not only need to make high-standard material selection but also need to continue to invest in design, process, and testing certification. Through scientific material selection and reliability verification, domestic connectors have every opportunity to achieve a balance between performance and cost, meeting the stringent demands of the automotive industry.
