Pre-Production Engineering & DFM / DFA Optimization
24-Hour DFM / DFA Audits: In-depth rule checks for minimum trace/space (2.5 mil), annular rings, solder mask dams, microvia aspect ratios, and component spacing to eliminate pre-production engineering queries (EQs).
Signal Integrity & Stackup Modeling: Polar SI9000-based impedance calculations for single-ended, differential, and coplanar waveguide traces with strict ±5% tolerance control.
Thermal & Power Plane Simulation: High-current optimization for heavy copper (up to 10oz), thermal relief routing, and heat sink placement in BMS and high-power inverters.
Authorized Component Sourcing & Supply Chain Services
100% Franchised Sourcing: Direct procurement via authorized distributors (Digi-Key, Mouser, Arrow, Avnet) with full manufacturer Certificates of Conformance (CoC) and lot date-code tracking.
BOM Cost Reduction & Lifecycle Alerts: Proactive identification of End-of-Life (EOL) or obsolete parts with drop-in, pin-compatible alternative cross-referencing.
Custom Buffer Warehousing: Dedicated ESD storage and bonded inventory management for rolling mass production contracts to protect against market shortages.
Precision Testing & Reliability Verification
Multi-Tier NDT Quality Gate: 100% 3D Solder Paste Inspection (SPI), dual-angle 3D AOI, and micro-focus 3D X-Ray inspection maintaining micro-BGA voiding rates strictly < 10%.
Custom ICT & FCT Fixture Engineering: Turnkey design of bed-of-nails In-Circuit Test (ICT) and Functional Circuit Test (FCT) fixtures with custom automated test software.
Environmental & Electrical Stress Labs: Metallurgical microsectioning (hole wall copper ≥ 25 μm), thermal cycling (−40°C to +125°C), and high-voltage Hipot testing (> 4000V AC).
