High reliability design
Triple-proof treatment: salt spray, moisture and mildew (triple-proof) coating is used to prevent marine environmental corrosion from causing circuit short circuit or failure.
Wide temperature operation: adapt to extreme temperature ranges from -40℃ to +85℃ to ensure stable operation in polar or tropical waters.
Anti-vibration/shock: Resist vibration and mechanical shock during ship navigation through reinforced design (such as metal frame, shock-absorbing material).
High integration and miniaturization
Ship space is limited, PCB cards need to integrate more functions (such as signal processing, communication, control) in a smaller volume, and multilayer boards (HDI) or high-density interconnection technology are often used.
Low power consumption and high efficiency
The ship power supply system is complex, and the card needs to optimize the power consumption design, extend the equipment life, and meet the real-time data processing requirements.
Electromagnetic compatibility (EMC)
Ship electronic equipment is dense, and the card needs to reduce electromagnetic interference through shielding design, filtering circuits and other measures to ensure signal integrity.
Key application scenarios of ship PCB card
Navigation and communication system
GPS/Beidou navigation module: integrated with high-precision positioning chip to support ship navigation safety.
VHF/MF/HF communication card: realize ship-to-shore and ship-to-ship voice/data transmission, which needs to be certified by the International Maritime Organization (IMO).
Power and propulsion control
Engine control unit (ECU): real-time monitoring of engine parameters (speed, temperature, pressure) to optimize fuel efficiency.
Thruster control card: control propeller speed through PWM signal, support dynamic positioning (DP) system.
Safety and monitoring system
Fire alarm card: integrated with smoke and temperature sensors, triggering sound and light alarms and linking fire extinguishing systems.
CCTV monitoring card: Process video signals and support remote monitoring of key areas such as cargo holds and engine rooms.
Automation and Internet of Things (IoT)
PLC control card: Realize automated control of ship equipment (such as pump stations and valves).
Sensor data acquisition card: Connect temperature, pressure, liquid level and other sensors to build the Ship Internet of Things (SIoT).
Design challenges and solutions for ship PCB cards
Environmental adaptability challenges
Challenges: Salt spray corrosion, mold growth, and sudden temperature changes.
Solution: Select corrosion-resistant substrates (such as CEM-3, PTFE) and use conformal coating to protect circuits.
Signal integrity challenges
Challenges: Long-distance transmission leads to signal attenuation and high-frequency noise interference.
Solution: Optimize wiring design (such as differential pairs, impedance matching), and add filtering circuits (such as magnetic beads and capacitors).
Certification and compliance challenges
Challenges: International standards must be met (such as IEC 60945, DNV GL, ABS).
Solution: Embed self-test function (BIST) in the design and pass the certification test of third-party organizations.
Future trend of ship PCB cards
Intelligent upgrade
Integrate AI chips (such as edge computing modules) to achieve fault prediction and autonomous decision-making (such as path optimization and energy consumption management).
Modular design
Adopt standardized interfaces (such as PCIe and CAN bus) to support rapid replacement and function expansion, and reduce maintenance costs.
Green and sustainability
Use lead-free solder and recyclable materials to comply with the RoHS directive and reduce the impact on marine ecology.
5G and satellite communication integration
Support high-speed data transmission to achieve remote monitoring, digital twins and other applications.
Typical cases
K-Pos dynamic positioning system of Kongsberg Maritime in Norway: Its PCB cards integrate multi-sensor fusion algorithms to support precise positioning of deep-sea drilling platforms.
Ship electric propulsion control card of China Shipbuilding Industry Corporation 711 Institute: Using SiC power devices, the efficiency is increased by 10%, suitable for LNG carriers.
Ship PCB cards are the “nerve center” of ship electronic systems, and their design must take into account performance, reliability and environmental adaptability. As the trend of ship intelligence and electrification accelerates, PCB cards will develop towards higher integration, lower power consumption and stronger adaptability, providing safer and more efficient solutions for the global shipping industry.
