At millimeter-wave frequencies, geometric precision determines electrical consistency. The HALA-CUSTOM-PS delivers ±2µm coil ID control, <±1.5µm (3σ) turn-to-turn pitch uniformity, and ±3µm (3σ) coil length tolerance — verified by 6-axis machine vision at 2µm/pixel resolution on every single coil. Tungsten carbide precision mandrels maintain <±0.5µm drift per 1M coils, and closed-loop servo wire tension (0.5–5.0gf, 100Hz bandwidth) ensures inter-winding gap uniformity <±2µm. Active shape-lock pneumatic extraction preserves geometry during mandrel removal.
Every coil is individually tested at >30 coils/minute: RF inductance at specified frequency (100MHz–20GHz), Q factor, self-resonant frequency, and DC resistance (4-wire Kelvin). Coils are binned by tolerance grade (±20% standard, ±10% precision, ±5% high-precision). This eliminates the sampling risk inherent in AQL-based lot testing.
Parameter changes (lead length, plating, tolerance) flow into the next production lot with zero tooling change. Geometry changes (custom coil ID or turn count) ship in 5–7 business days with full verification cycle. Each coil receives a unique 2D data matrix linking to per-coil RF test records, wire spool genealogy, process parameters, optical inspection images, and S2P Touchstone characterization data — full digital twin traceability from raw material to finished coil.
