Automotive PCB manufacturing supports vehicle electronics requiring AEC-Q200 qualified components, extended temperature operation (-40 to +125°C), functional safety per ISO 26262, and 15+ year reliability across ADAS sensors, infotainment systems, powertrain controllers, and body electronics demanding robust construction surviving vibration, thermal cycling, and harsh environments throughout vehicle lifecycles with zero-defect expectations in safety-critical applications.
At APTPCB, we manufacture automotive PCBs with automotive electronics expertise implementing qualified processes, validated materials, and comprehensive testing supporting ADAS through powertrain applications.
Achieving AEC-Q Qualification and Automotive Standards
Automotive components require AEC-Q100 (ICs) and AEC-Q200 (passives) qualification validating reliability through extreme temperature cycling, humidity testing, and mechanical stress. Qualification challenges include extended temperature ranges (-40 to +150°C junction), qualification sample sizes, and long-term reliability validation. Inadequate qualification causes field failures from thermal stress, premature wear-out, or environmental degradation — significantly impacting warranty costs and brand reputation.
At APTPCB, our manufacturing implements automotive-qualified processes achieving long-term reliability.

Through automotive-qualified manufacturing and comprehensive validation coordinated with NPI assembly development, APTPCB delivers automotive PCBs meeting industry reliability requirements.
Implementing Functional Safety per ISO 26262
Safety-critical automotive systems (ADAS, braking, steering) require functional safety implementation per ISO 26262 achieving ASIL-B through ASIL-D ratings through redundancy, diagnostics, and safe-state management. Safety challenges include implementing hardware safety mechanisms, achieving >90% diagnostic coverage, and validating systematic capability. Inadequate safety implementation prevents certification, causes liability exposure, or creates actual safety hazards — significantly impacting product viability in ADAS and autonomous vehicle markets.
At APTPCB, our manufacturing supports functional safety designs achieving ASIL compliance.
Functional Safety Implementation
- Redundant Architecture: Dual processors, sensors, or power supplies enabling continued operation despite single faults.
- Diagnostic Coverage: Self-test routines and hardware monitors detecting >90% of potential faults per ASIL requirements.
- Safe-State Management: Controlled shutdown or degraded operation during detected faults preventing unsafe conditions.
- Development Process Compliance: ISO 26262 design practices, DFMEA, and validation per automotive safety standards.
- Systematic Capability: Manufacturing processes achieving required failure rates and avoiding systematic errors.
Through functional safety expertise and validated processes, APTPCB enables safety-critical automotive applications achieving ISO 26262 compliance.
Supporting ADAS and Autonomous Vehicle Applications
Advanced driver assistance and autonomous vehicles integrate radar, cameras, lidar, and sensor fusion requiring high-speed data processing, automotive Ethernet networking, and functional safety. ADAS challenges include sensor data synchronization, deterministic processing latency, and redundant architecture for fail-operational systems. Inadequate ADAS implementation affects system performance, prevents safety certification, or limits autonomous capability — significantly impacting competitiveness in automated driving markets.
At APTPCB, we support ADAS manufacturing with specialized processes and validation.
