Industry 4.0 & Beyond

The ‘Industry 4.0 Digital Revolution’ signifies a profound transformation within manufacturing and industrial processes. It’s powered by a suite of interconnected technologies that drive ‘smart’ systems, hyper-automation and data-driven decision-making at unprecedented speeds. Primary Industry 4.0 capabilities stem from this fusion of technologies, allowing for intelligent systems across various sectors; such as Autonomous Robots, Big Data and the Industrial Internet of Things (IIoT).

Smart Reliance on PCBs: To support the precision and connectivity that new-wave automated industrial applications demand, smart factories require dedicated electronics (machinery and equipment), enabled by advanced PCB technology.

For Today’s Electronics & Future Innovations:

Soft Robotics/Wearable Electronics: Using Flexible & Stretchable PCBs to enable conformable, bio-integrated robotics, like soft grippers or wearable exoskeletons that require non-planar electronics.

Additive Manufacturing (3D Printing): Using 3D-Printed PCBs for new or non-traditional circuit geometries with rapid prototyping; potentially integrating electronics directly into the product structure.

Artificial Intelligence (AI) at the Edge: PCBs with Integrated AI Accelerators, that incorporate complex, thermally managed boards to run machine learning models directly on factory floor equipment; for immediate decision-making, as with real-time visual quality control.

Advanced Traceability: PCBs with Embedded Traceability Codes. Miniaturized barcodes or RFID tags integrated into the PCB layers for end-to-end tracking of every board; enabling quality control and predictive maintenance.

Industry 4.0 Applications

PCBs are embedded in virtually every component of the smart factory ecosystem, enabling interconnected, autonomous, real-time operations for key applications:

1. Advanced Industrial Robotics (Robots and Cobots):

• Real-Time Motion Control: Multi-layer and High-Density Interconnect (HDI) PCBs house high-performance processors and motion control drivers, crucial for real-time communication protocols like EtherCAT or PROFINET, for precise, coordinated robotic movements.
• Sensor & Actuator Interfacing: To connect and manage an impressive array of embedded sensors, for torque, position, force feedback and actuators (servo motors).
• Flexible Circuits in Articulated Arms: Flexible (Flex) & Rigid-Flex PCBs are used in joints and articulated sections of robotic arms. Allows high-cycle bending while maintaining signal integrity and reducing overall weight and size of the arm.

2. Smart Sensors & Industrial IoT (IIoT) Devices:

• Miniaturization: HDI PCBs with Micro-vias and component embedding technology are essential for creating the small form factors required for IIoT sensors, fitting into constrained spaces on machinery or assembly lines.
• Edge Computing: Integrating low-power microprocessors to perform local data processing and filtering at the sensor level; reducing latency and data volume sent to the cloud.
• Connectivity: Supporting various wireless communication modules (Wi-Fi, 5G, LoRa) and managing the high-frequency signals required for reliable data transmission in crowded industrial environments.

3. Autonomous Guided Vehicles (AGVs) & Drones:

• Navigation & Control: Operation of flight-control and vehicle-control boards; integrating high-speed computation, inertial measurement units (IMUs), GNSS (Global Navigation Satellite System) receivers and motor control circuits.
• Lidar/Radar Modules: For Advanced Driver Assistance Systems (ADAS), housing the high-speed signal processing units for Lidar, radar, and machine vision cameras that enable obstacle detection and real-time mapping.

Demands for Specialized Industrial PCBs

PCB Technologies provide our customers in the industrial sector with advanced capabilities that meet the exacting demands of the digital industrial revolution. We offer PCB solutions directly responsible for helping to overcome the limitations of older automation systems, while also serving new-wave industrial needs.

• High-Density Interconnect (HDI) & Miniaturization: Smaller, more powerful electronics require HDI PCB technology for finer lines, tighter spacing and tiny connections (micro-vias), that increase component density; allowing for more complex control circuitry, processors and communication chips to be packed into less space.
• Durability in Harsh Environments: Industrial settings are often characterized by extreme conditions, (temperature, electronic noise, chemicals etc.), demanding extra durable PCB operation.
• Ruggedized Materials: PCB materials and laminates must withstand vibration, shock, dust, chemicals and wide temperature ranges (-40^ to 85^).
• Heavy Copper PCBs: Thicker copper layers used for high-power applications, such as motor control or power supplies. Heavy Copper PCBs manage high currents (up to 100A or more), acting as natural heat sinks to dissipate heat.
• Signal Integrity & Speed: Elevated data rates for real-time control and vision systems require high-frequency PCBs using materials with low dielectric loss to ensure minimal signal loss, interference or distortion at high frequency transmission (above 1 GHz).
• Controlled Impedance: PCB design must ensure that characteristic impedance of transmission lines (traces) is precisely controlled (~ 50 ohms) preventing signal reflection, noise or data corruption in high-speed protocols.
• EMI Shielding: Multilayer PCBs and specialized routing techniques provide robust electromagnetic interference (EMI) shielding, enabling clean signals in electrically noisy factory settings.
