Customer Project Scenario — High-Reliability Automotive Electronics

A global Tier-1 automotive electronics supplier partnered with LinkPCBA to produce a control board used in a fuel-injection ECU subsystem.
The project required:
- Stable performance under wide temperature ranges (-40°C to 125°C)
- Consistent impedance and multilayer reliability during high-current operation
- Automotive-grade solder joint durability and vibration resistance
- End-to-end traceability across all PCB and PCBA processes
- Small-batch verification followed by rapid volume ramp-up
LinkPCBA provided a fully validated PCB + PCBA manufacturing solution enabling early engineering verification and fast transition to mass production.
Technical Challenges Faced in Automotive Electronics
Automotive electronics operate in harsh and safety-critical environments. Common engineering challenges include:
- High-temperature and high-humidity endurance
Continuous operation in extreme conditions requires stable materials, precise lamination quality, and long-term dielectric reliability. - Vibration, shock, and fatigue resistance
Automotive modules must maintain solder joint strength and structural integrity over years of vibration cycles. - High-current and heat-management requirements
Power control units, BMS boards, and motors require thick-copper, low-loss structures, or thermal-enhanced PCB designs. - Zero-defect SMT and process repeatability
Automotive projects demand strict process control, detailed traceability, and batch-to-batch consistency. - Safety & functional reliability
From ADAS to braking systems, reliability and failure-proof performance are essential.
