Automotive EMI Shielding

Electronic Control Units (ECUs) are the nervous system of modern vehicles. Each ECU requires board-level shielding to:

• Contain emissions from high-speed processors and switching regulators
• Protect sensitive inputs from ignition noise and motor drive interference
• Meet CISPR 25 radiated emission limits

Our two-piece shield assemblies allow rework access during development while providing 40-60 dB shielding effectiveness in production.

Advanced Driver Assistance Systems (ADAS) combine radar, lidar, cameras, and ultrasonic sensors—each with unique EMI challenges:

• 77 GHz radar modules require precise RF isolation
• Camera processors need protection from high-frequency interference
• Sensor fusion units combine multiple signal types requiring multi-cavity shields

POCONS provides custom shield configurations for ADAS applications, including multi-cavity designs that isolate different functional blocks within a single assembly.

Electric vehicle power electronics present unique EMI challenges due to high switching frequencies and power levels:

• Battery Management Systems (BMS) require isolation from high-voltage switching noise
• DC-DC converters generate significant conducted and radiated emissions
• Onboard chargers must meet strict EMC limits during charging cycles

Our components are qualified for high-temperature automotive environments and provide the shielding effectiveness needed for EV applications.

Infotainment systems combine WiFi, Bluetooth, cellular, GPS, and digital radio—all requiring careful RF management:

• Multi-band antenna modules need isolation between transmit and receive paths
• Audio processors require protection from digital switching noise
• Display drivers generate high-frequency emissions that can interfere with radio reception

POCONS provides integrated shielding solutions that address the complex RF environment of modern infotainment systems.

Automotive qualification requires more than just component performance—you need a supply chain that meets IATF 16949 requirements:

• Full traceability from raw material to your production line
• PPAP documentation packages for your qualification process
• Statistical process control ensuring consistent quality
• Change management procedures that protect your production

POCONS maintains IATF 16949 certification and provides complete documentation packages for automotive qualification programs.
