At APTPCB, we deliver specialized ADAS assembly services implementing safety-qualified processes, sensor integration, and real-time platforms with turnkey assembly capabilities supporting diverse ADAS features and autonomy levels.

Achieving ISO 26262 Functional Safety Compliance

ADAS safety functions require ISO 26262 compliance achieving ASIL-B (warning systems) through ASIL-D (active intervention systems) through safety analysis, architectural safety mechanisms, and validation activities demonstrating systematic and random hardware failure targets. Functional safety challenges include implementing comprehensive diagnostics achieving >90% coverage, validating fail-safe transitions to safe states, and demonstrating safety throughout development lifecycle. Inadequate safety implementation prevents certification, creates liability exposure, or results in actual safety incidents — significantly impacting product viability, legal compliance, and market introduction as ADAS adoption accelerates and regulatory requirements strengthen.

At APTPCB, our assembly implements ISO 26262 compliant processes achieving ASIL-B through ASIL-D ratings for safety-critical ADAS functions.
