With the intensification of domestication and the substitution of defense equipment with domestic alternatives, terminal equipment has higher requirements for the reliability, environmental adaptability, and traceability of connectors. This article combines the capabilities of Foxconn Interconnect Technology (FIT) in connector manufacturing and certification with the typical requirements of military-grade (MIL-STD, etc.) components, systematically analyzes whether domestic connectors can be certified as "military-grade versions," the key conditions that need to be met, and how enterprises should plan their research and development and certification paths.
What is the "military product certification version"? What typical standards need to be met?"Military product certification version" generally refers to the components passing stringent environmental and reliability tests for military, aerospace, marine, and other harsh conditions, and meeting the requirements of the military/system integrator in terms of design, process, inspection, and traceability. Common test specifications or reference standards include environmental and durability tests (such as MIL-STD-810), basic environmental accelerated stress tests for electronic components (such as MIL-STD-202), and RTCA/DO-160 for system-level requirements. Different countries and purchasers may have specific acceptance procedures and customized verification items.
Part Two: Comparison with FIT (Foxconn Interconnect Technology): Existing Capabilities and Differences●FIT's capabilities: FIT is a business unit under Foxconn Group in the interconnection and component direction, with capabilities in stamping, mold-making, coating, automated assembly, and mass production. Its products cover multiple high-reliability fields such as computers, communications, automobiles, and industries. Its global manufacturing and quality system is an important foundation for supporting the introduction of complex customers.
●Common practices in the industry for producing military-grade components: Many military/aerospace-grade connector suppliers adopt vibration-resistant shell structures, special coatings (such as thick gold, electroless nickel/gold plating), special sealing, and salt mist resistance treatment, and conduct additional reliability amplification tests and full manufacturing traceability systems. There are already manufacturers on the market that offer circular or modular connectors that meet MIL-STD-202 / MIL-STD-810 as regular product lines.
The key issues to be addressed for domestic connectors to move towards "military-grade" (technology + management)Materials and Surface Treatment
Terminal material, coating thickness, and process (thick gold, nickel plating, anti-chloride layer) directly affect contact reliability and anti-corrosion ability. To pass military standard tests, there must be clear specifications and batch control for materials and processes.
Design for durability and mechanical strength
The military environment requires high vibration, high impact, wide temperature range (high/low temperature cycling), salt mist, humidity, and other factors. The locking mechanism, positioning, and back support design of connectors must be able to withstand higher mechanical and thermal stresses.
3. Reliability Test Capability (Laboratory Qualification)
●The enterprise must have or entrust a qualified laboratory to perform projects such as MIL-STD-810, MIL-STD-202, salt spray, vibration, shock, and thermal cycle, and produce auditable test reports and original data.
Process consistency and process control
●Military parts have extremely strict requirements for the manufacturing process: first article inspection, process capability (Cp/Cpk), welding technology, assembly operation manual (SOP), fixture and gauge control, etc., all of which need to be realized through documentation and long-term management and control.
5. Quality System and Traceability
Complete material batch tracking, key process records, shipment inspection records, and failure traceability mechanisms are rigid requirements for military supply chains. Suppliers also need to undergo on-site audits and regular audits by customers.
6. Compliance and Supply Chain Security
The procurement of military products requires more consideration of supply chain compliance, alternative material risks, and the source of key materials. Enterprises need to establish strict supplier management and alternative material assessment processes.
How can domestic manufacturers develop a feasible "military product" path (recommended route)?1. From high reliability commercial to military productization: choose product lines with high reliability requirements in automotive, industrial, and communication sectors as breakthroughs, first through higher-level reliability tests and long-term life verification to accumulate data and process capabilities; then gradually approach military standards.
Establish or cooperate in testing capabilities: Collaborate with authorized third-party testing laboratories or qualified laboratories within the national defense/military system to complete MIL-STD and other certification tests, and form reviewable test reports and long-term data.
Material and process upgrade in sync: Conduct special verification for key materials (terminals, shells, seals) and surface treatment (thick gold, special coating), and perform accelerated aging and environmental adaptation verification.
4. Process and Quality Management System Certification: Promote the management of systems such as ISO 9001 / IATF 16949 (may also be required if entering the automotive industry), establish production process capability indicators, and continuously improve.
Develop customer-specific specifications and joint verification: Collaborate with system integrators or military technical teams for prototype testing and scenario-based verification to meet customers' customized special operating conditions.
Document and traceability construction: Improve production traceability, batch management, inspection records, and failure analysis systems to meet strict audit and recall management requirements.
Five, Opportunity and Reality: Can domestic connectors achieve military product certification version?Realistic judgment: Domestic manufacturers with the necessary conditions have the full ability to develop and mass produce "military-certified version" connectors, but this requires systematic investment in materials, technology, testing capabilities, and quality management, and long-term reliability verification and customer audit. Taking enterprises like FIT / Foxconn, which have large-scale manufacturing and mature quality systems, as a reference, if domestic enterprises can reach the same level in several key links (surface treatment, process stability, testing and traceability), they can provide qualified products for military or quasi-military specification applications.
Opportunities: The national support for the localization of key electronic components, civil-military integration projects, and the demand for local supply chains provide policy and market momentum for domestic connectors to enter the military field. As long as enterprises can achieve "technically verifiable, quality traceable, and supply guaranteed," there is a high probability of obtaining opportunities for military or national defense-related projects.
To make "domestic connectors" into a true "military-grade certified version," the key does not lie in a slogan but in the enterprise's willingness and ability to invest continuously in material and process upgrades, testing capability construction, process control, and quality system, as a long-term engineering project. Technical, testing, and management thresholds can all be overcome; however, they require the enterprise to place quality first and treat data and traceability as core competitive strengths. For domestic enterprises that already have scaled manufacturing and R&D capabilities, military-standardization is an achievable strategic goal and also the inevitable path to entering the high-end market.
