COAX Connectors Connector Domestic Alternative Selection and Qualification Audit Key Points

Under the premise of ensuring the stable and reliable operation of electronic communication systems, whether domestic connectors can become a qualified alternative solution for international high-performance RF connectors such as COAX Connectors requires strict review from multiple dimensions such as product performance, production qualifications, and cooperation capabilities. The following are several key review points:

Understand COAX Connectors brand and product characteristics
COAX Connectors is a British company specializing in the design, manufacturing and supply of high-performance RF connectors and cable assemblies. Its products cover a wide range, including miniature connectors for 50Ω and 75Ω systems (such as the True 75Ω with a height of only 3 mm at 0.4/2.5 mm), as well as common models such as SMA, BNC, and N-Type.

The product line also includes cable components, special tools (such as crimping tools, extraction tools, strippers, etc.), protective accessories (protection caps, tension relief kits, washers, etc.), and customized connector design services.

Second, key points for the technical review of domestic substitute products
1. Electrical performance matching: Focus on comparing key parameters such as impedance (50Ω/75Ω), VSWR, insertion loss, and loop loss. The goal is to match the high RF integrity standards provided by COAX Connectors.
2. Mechanical structure and environmental resistance: Check interface dimensional tolerances, wear resistance, insertion and removal cycles, IP ratings (such as whether it reaches IP68) to meet harsh environmental conditions.

Material and Processing Technology: Inspect metal materials, plating (such as nickel, gold), injection molding, and sealing technology to ensure long-term stability and corrosion resistance.

Three, key points for qualification and quality management audit
System certification: Whether it has ISO 9001, ISO 14001, and product special certification (such as military and communication industry certifications).
2. Design and R&D capabilities: Whether it has an independent R&D team that can provide a closed-loop service from concept evaluation, sample production, testing and verification to mass production, similar to COAX's "Custom Connector Design Service".
3. Production equipment and process control: Are modern CNC machining, automatic testing equipment, environmental aging and mechanical cycle testing equipped?

4. The quality control process: whether the incoming inspection, IPQC (in-process quality control), FQC (final quality control), OQC (outbound quality control), etc., are complete.

Four, key points for supply chain and delivery capability audit
Capacity and delivery guarantee: Do you have the ability to produce samples quickly and deliver goods on time, and can you respond to sudden demands?
2. Tool and accessory services: Can you provide special tools and protective accessories that match the connectors, such as the tools and protective accessories provided by COAX?

3. Technical Support and After-sales Capability: Does it have a stable team of engineers capable of timely responding to customer scheme adjustments and after-sales services.

When auditing domestic connector suppliers, it should be carried out from multiple aspects such as electrical and mechanical performance, quality system, research and development and production capacity, supporting tools and delivery capability. Only when the indicators are close to or match international standards such as COAX Connectors, can the true domestic substitution be achieved and reliable guarantees provided for communication and broadcasting equipment.
