QUICK ACCESSUse the project interface, structure, and application requirements to move into the right content.

Before detailed specification review begins, most micro-coaxial programs first need to confirm the connector family, pitch, wire gauge, impedance target, shielding structure, and verification scope. This stage is less about rushing into samples and more about defining the technical boundaries correctly.

Specification
REF-05For mixed-media assemblies that combine copper power, micro-coax signal, and fiber channels in one controlled harness.
Specification
REF-06For 50 ohm, 75 ohm, and 100 ohm micro-coax programs that need TDR, VNA, termination consistency, and test records.

Application
REF-04For server, switch, BMC, patch-panel, and hyperscale programs that need dense routing and batch stability.
Micro-coaxial engineering is usually driven less by part count than by whether the connector combination, wire gauge choice, shielding structure, and termination details are already settled. If those points are still in flux, samples, drawings, and process review tend to loop.
Receive connector models, pin definitions, wire specs, length requirements. Confirm wiring method (Pin1-to-Pin1 or custom pinout) and special requirements (impedance, shielding, bend radius).
Match optimal wire and connector combinations. Evaluate production feasibility and identify process risk points (stripping precision for ultra-fine wire, soldering gaps for high-density connectors).
Issue standard engineering drawings with complete pinout definitions, dimensions, BOM, and process requirements — all per IPC/WHMA-A-620 standards.
Production begins only after customer drawing approval. This confirmation step ensures both parties agree on specifications, avoiding rework and waste.

Connector-fit and routing-space review
Micro-coaxial programs usually carry tighter requirements around precision termination, impedance consistency, shielding execution, and batch-to-batch variation control. Rather than making broad quality claims, it is more convincing to show the actual risks, verification items, and release criteria. Confidence comes from inspection logic, test results, and version-linked records.
The main micro-coaxial risks usually sit in broken cores, cold solder, impedance drift, weak crimps, and jacket damage. The practical question is not broad quality language, but whether those failure modes are controlled before they turn into batch issues.
Typical verification covers Continuity, Hi-Pot, Insulation Resistance, Pull Force, TDR Impedance, Visual Inspection, together with microscope-based visual inspection, so precision termination, impedance consistency, and assembly condition all stay inside the released limits.
Typical release files include FAIR, OQC Report, IQC Report, Test Report, CoC, with compliance support such as ISO 9001:2015, ISO 13485, and UL when the program requires it.
