Domestic COAX Connectors High-Quality Process Unveiled

COAX Connectors is a leading British company specializing in the design, manufacturing, and supply of high-performance RF (radio frequency) connectors and cable assemblies, renowned for its rigorous design capabilities and full-process services. Whether it is from initial problem analysis, design concepts, rapid prototyping, to testing and certification, as well as mass formal supply, COAX can provide complete end-to-end services. This high-standard quality process provides us with a valuable reference sample in the research and development and production of domestic connectors—we are committed to creating domestic substitute products that meet or exceed international brand standards.

One, details of the quality inspection process for domestic connectors
Design Review
The core structure design and material selection must meet the requirements for high-frequency signal transmission, such as maintaining good impedance matching (50Ω / 75Ω) and signal shielding effect.
●Use high-quality materials (brass or Beryllium copper, with surface coatings such as tin/silver/gold, etc.) to ensure a balance between conductivity and corrosion resistance.
Sample Preparation and Rapid Prototyping
●The preliminary batch of samples is used for assembly, mechanical strength, and environmental adaptability tests, simulating field use (such as waterproofing, dustproofing, and durability of plugging and unplugging).
3. Test and Certification (Qualification)
● Includes electrical performance (insertion loss, return loss), mechanical performance (insertion/removal cycles, tensile strength), and environmental adaptability (temperature cycling, humidity and heat, vibration) tests. COAX provides full-process support from design to certification.
4. Process Control (Manufacture & Quality)
In mass production, strictly control the key process steps, such as crimping/welding quality, coating thickness, consistency testing, etc., to ensure that each batch of products is stable and reliable.
5. Final Inspection and Shipment

Inspection of appearance, dimensions, and electrical performance for each batch of products is conducted, and environmental durability tests are carried out as necessary to ensure that the connectors meet the standard performance upon shipment.

Industry General Quality Requirements Comparison
Material and electrical properties
High-quality connectors use brass or beryllium copper, and the surface finishing layer (silver, gold) improves conductivity as well as enhances oxidation resistance.
Impedance consistency
It is crucial to maintain a constant impedance at higher frequencies (such as SMA that can reach 18-26.5 GHz).
● Connection methods and applicability

Common types such as BNC (quick disconnect), TNC (threaded stabilization), SMB (high-frequency small-size), and N-type (high power, industrial grade) cater to different application scenarios and frequency bands.

How can domestic connectors achieve high quality?
● Leveraging the COAX full-process concept: referring to its overall process model from design, testing to certification, for the systematic upgrading of the domestic design system.
● Select high-quality materials: Optimize material selection and plating process to enhance conductivity and durability.
Fine craftsmanship control: Strictly implement process quality control and strengthen inspection standards.

●Performance benchmarking with international standards: Ensure that domestic connectors reach international standards in terms of signal transmission, mechanical durability, and protective performance.

By introducing a full-process quality system for COAX Connectors and optimizing and strictly controlling the design, materials, manufacturing, and testing of domestic connectors, it is possible to create reliable and high-performance domestic RF connectors. This not only reduces procurement costs but also enhances the autonomy and responsiveness of the local supply chain, providing customers with cost-effective, quality-assured connection solutions.
