EV & Autonomous Vehicle Manufacturing Solutions
PCBLion provides end-to-end electromechanical manufacturing for the automotive sector. From high-density PCB assembly to high-voltage wire harnesses and ruggedized box builds, we deliver zero-defect solutions for mission-critical vehicle systems.
Automotive PCB Assembly (PCBA)
The compact and high-density designs of modern EVs require robust PCBA techniques. We specialize in Heavy Copper (up to 14oz) for power dissipation and HDI Any-Layer technology for complex logic circuits. Every board undergoes 100% 3D SPI and X-Ray inspection to ensure solder joint integrity under vibration.
- Powertrain & Power: Battery Management Systems (BMS), On-Board Chargers (OBC), DC-DC Converters, and Motor Controllers.
- ADAS & Safety: Radar/LiDAR processing boards, Airbag Control Units (ACU), and Vehicle Control Units (VCU).)
- Body & Cabin: Instrument clusters and Body Control Modules (BCM).
Custom Cable & Wire Harness Assembly
EVs require complex power distribution and noise-free data routing. We manufacture custom cable assemblies designed to minimize Electromagnetic Interference (EMI) and prevent short circuits in harsh environments.
- High-Voltage (HV): Power distribution harnesses for charging infrastructure, battery packs, and inverter-to-motor connections.
- Data & Sensors: Shielded communication cables for ADAS sensors, actuators, and telematics networks.
- Interior Systems: Infotainment and safety system wiring arrays.
Electromechanical Box Build Integration
PCBLion offers turnkey Box Build assembly, integrating sensitive electronics into custom mechanical enclosures (plastic or die-cast metal) to achieve automotive-grade durability and IP67+ weatherproofing.
- System Assemblies: Fully integrated Power Distribution Boxes (PDU), Inverter assemblies, and Energy Management modules.
- Protection: Automated Conformal Coating and Potting services to protect against salt spray, moisture, and chemical corrosion.
- System Testing: End-of-line Functional Circuit Testing (FCT), Hi-Pot (High Voltage Isolation) testing, and Burn-in aging.
Full-Vehicle Electronics Manufacturing Capabilities
We don’t just understand the vehicle’s architecture; we engineer the PCB solutions required for each domain’s unique thermal and electrical challenges.
EV Powertrain & Battery Management (BMS)
Managing massive currents (up to 200A) and dissipating extreme heat in compact enclosures.
We fabricate Heavy Copper PCBs (up to 14oz) and Direct Thermal Path (DTP) Metal Core boards. Our lamination process uses high-flow prepregs to ensure void-free insulation for high-voltage (800V) platforms, strictly preventing dielectric breakdown.
Safety Systems & ADAS
Zero-tolerance for signal loss or solder joint failure in Airbag Control Units (ACU), ABS, and 77GHz Radar.
Manufactured strictly to IPC-A-610 Class 3 standards. We utilize hybrid stack-ups (Rogers RO4835 + FR4) with precise ±0.0005" etching tolerances for radar antennas, verified by 100% 3D X-Ray (AXI) for BGA solder joint integrity.
Domain Controllers & Infotainment
Routing high-pin-count processors (SoCs) and memory modules within a highly constrained dashboard space.
We deploy Any-Layer HDI technology (up to 7+N+7) with 3mil laser-drilled microvias. Our VIPPO (Via-in-Pad Plated Over) process ensures perfectly flat pads for 0.35mm pitch BGAs, guaranteeing high-speed data transmission (PCIe, Automotive Ethernet).
Body Control Modules (BCM) & Sensor Arrays
High-mix assembly of hundreds of sensors (temperature, pressure, proximity) and lighting drivers exposed to dust and moisture.
We offer automated Conformal Coating (Acrylic/Silicone) to protect boards from harsh cabin environments. Our MES traceability system records every component lot code for 15+ years to support your PPAP requirements.
