HALA-CUSTOM-FX: In-House Flex-Tooling & Advanced Failure Analysis Air Core Inductor

In-House Flex-Tooling & Fast Turnaround

The HALA-CUSTOM-FX eliminates external tooling dependencies entirely. Mandrel fabrication (tungsten carbide, precision-ground to customer-specified ID), winding parameter programming (closed-loop servo tension, turn count, pitch), and lead-forming tooling are all performed in-house on the HALA precision automated winding platform. This vertical integration reduces prototype turnaround from the industry-standard 2–3 weeks to 24 hours. Design received by 12:00 CST ships prototype coils the same business day with full S2P Touchstone characterization and optical inspection data. For non-standard geometries — custom coil IDs, non-circular cross-sections, asymmetric lead configurations — the in-house tooling approach avoids the 4–6 week lead time and NRE charges typical of external tooling vendors.

Advanced Failure Analysis & Life-Test Reports

Every qualification lot includes a comprehensive failure analysis and life-test package at no extra charge:

• Cross-Section Analysis: SEM imaging at 500*–5000* magnification, EDX elemental mapping for plating thickness and intermetallic compound (IMC) layer characterization, optical micrographs of wire-to-lead interface
• Thermal Cycling: IEC 60068-2-14 Na, -55 to +125°C, 500 cycles, with inductance and Q factor measurements at 0/100/250/500 cycle intervals — full drift analysis with before/after S2P overlay plots
• Constant Acceleration: JESD22-B103, Condition E (30,000g), Y1 orientation, pre- and post-stress electrical test
• Mechanical Shock: JESD22-B104 Condition B, 1500g 0.5ms half-sine, 5 shocks per axis * 6 axes, full waveform capture and pre/post electrical comparison
• Random Vibration: JESD22-B103, 20g RMS, 50–2000Hz, 4 minutes per axis, pre/post electrical comparison
• Solderability: JESD22-B102 steam-aged 8 hours, dip-and-look at 3*–10* magnification, wetting balance analysis
• Accelerated Life Test: Weibull distribution analysis, MTTF estimation at use condition, activation energy per Arrhenius model — full statistical report with confidence intervals

All FA reports include raw data files (SEM images, EDX spectra, S2P files, waveform captures) and are reviewed by a senior applications engineer before delivery. Direct engineer-to-engineer consultation on FA results, corrective action planning, and Weibull life prediction is included at no charge for every qualification lot.

100% RF Electrical Testing at All Volumes

Every coil receives 100% per-coil RF testing (L, Q, SRF, R_DC) — not sampled, not AQL-based. Per-coil 2D data matrix identification links each coil to its test record, wire spool genealogy, process parameter log, and FA report. This full lot traceability architecture ensures that if a field return occurs, the exact manufacturing conditions and test results for that specific coil can be reconstructed — critical for root cause analysis and corrective action.
