A European automotive Tier 1 supplier is developing an exterior LED lighting control board for passenger vehicles. The product must operate under vehicle vibration and wide temperature cycling.
Key Challenges
Technical: AEC-Q100 automotive components must withstand -40℃ to +125℃ thermal cycling and mechanical vibration.
Manufacturing: Solder joint reliability under long-term vibration.
Compliance: Full traceability required for automotive quality audit.
MTI End-to-End Solution
Automotive DFM Review: Copper layout and pad design optimized to enhance solder joint vibration resistance, with high-Tg PCB material recommended for thermal cycling. Automotive SMT Assembly: Strict reflow profile for AEC-Q components and AOI inspection of all solder joints. Environmental Reliability Test: Thermal cycling, vibration aging and functional testing to simulate vehicle working conditions. Supply & Traceability: AEC-Q100 devices sourced from authorized automotive distributors with all lot numbers recorded. Box Build Integration: Full enclosure assembly and final system integration for the automotive auxiliary electronic system.
Final Outcomes & Measurable Value
Reliability: The PCBA passed automotive thermal cycle and vibration testing with no solder joint crack after long aging tests. Audit Support: Complete batch records ready for automotive quality system audit. Production Ramp: Successfully ramped from prototype to serial production for the vehicle lighting module.
