A Detailed Discussion on Rising Trends and Challenges in PCB Designing
The complexity in PCB designs and assemblies is applicable in precision-demanding and mission-critical applications, including medical, aerospace, automotive, and defense. Continual research and innovation done to meet these complex requirements brings its own sets of trends and challenges along. Let’s understand this through an example. Developing autonomous vehicles or self-driving cars offers both opportunities and challenges for PCB design and fabrication players. Here, advanced sensor integration, high-speed data processing systems, and power efficiency are some opportunities, while safety-critical designs, regulatory compliance, and reliability are a few challenges. Below are some PCB designing trends and challenges that may shape the future of industries.

  • High-Power PCBs: These are rapidly emerging as a significant trend in PCB designing, driven by the increasing demand for compact yet powerful electronic devices across industries. They are designed to handle high levels of power and heat dissipation, enabling seamless integration of advanced components such as power transistors, amplifiers, and high-wattage LEDs. Critical advancements in manufacturing processes and materials have facilitated the development of high-power PCBs, allowing for enhanced thermal management, reduced electrical losses, and improved overall performance. Additionally, the increasing production of electric vehicles, renewable energy systems, and industrial automation applications has fueled the adoption of high-power PCBs as these technologies rely heavily on robust power electronics. The challenges here are related to heat generation and EMI issues.
  • High-density Interconnects (HDI): HDI technology allows for integrating intricate circuitry into increasingly compact spaces. This facilitates the creation of densely packed boards with multiple layers and fine-pitch components. By leveraging advanced fabrication techniques, such as laser drilling, microvias, and sequential buildup processes, they offer reduced electromagnetic interference, enhanced signal integrity, and improved reliability compared to traditional boards. HDI PCBs are driven by diverse industries, including consumer electronics, telecommunications, and medical devices, where miniaturization and performance optimization are paramount. With the increasing demand for high-performance, space-constrained electronic solutions, HDI technology plays a pivotal role in enabling next-generation PCB designs that push the boundaries of size, functionality, and performance. Component mounting and wiring in HDIs, although automated, can pose challenges at times.
  • IoT: The Internet of Things (IoT) revolutionizes how electronic devices interact and communicate in various industries. With the rise of interconnected smart devices with their sensors, and actuators, PCB designers are experiencing the challenge of developing highly optimized and efficient circuitry to support IoT functionalities. IoT PCBs combine wireless communication modules, low-power microcontrollers, and sensor arrays, all within compact form factors. As IoT applications continue to expand across domains like healthcare, smart homes, agriculture, and industrial automation, designers are innovating with new materials, miniaturization techniques, and integration strategies to meet the evolving demands of this interconnected ecosystem. The emergence of IoT is reshaping circuit board design in many ways and driving the development of multifunctional circuitry to power the connected world of tomorrow. The small size of boards is one of the major challenges even if automation is used.
  • Supply Chain Controls: This trend is driven by the growing awareness of supply chain risks and the need for greater resilience and transparency. PCB designers need to design PCBs that meet these requirements in terms of establishing secure supply chain networks, and verifying the authenticity of components to mitigate the risks of counterfeit parts, shortages, or disruptions. With the globalization of supply chains, geopolitical tensions, and regulatory complexities, PCB designers are introducing advanced technologies, such as digital twins and AI-driven analytics, to enhance visibility, traceability, and accountability across the supply chain systems. The challenge is to understand the growing complexities in supply chain management systems which may differ based on region, part availability, frequency of shipping, and other such parameters.
  • COTS Components: The use of commercial-off-the-shelf (COTS) components has grown over the years. This enhances the reliability and improves the design process for critical and space-confined parts. COTS components are available from established vendors, offering designers a wide range of standardized options for various functionalities, such as microcontrollers, sensors, and wireless modules. Using COTS components, PCB designers can streamline the design process, reduce development cycles, and minimize manufacturing costs. While COTS components offer several benefits, designers must consider factors such as compatibility, reliability, and long-term availability to ensure their designs’ overall quality and longevity. As the demand for unique and innovative electronic devices continues to grow, integrating COTS components into PCB designs is expected to become increasingly prevalent, thus increasing efficiency and competitiveness in the electronics industry. Businesses widely prefer custom options over COTS, and this is one of the challenges here.

These trends as well as challenges highlight the dynamic nature of modern circuit board design and emphasize upon the need for continual innovation and research. The challenges, particularly in areas like HDI implementation, high-power PCBs, and IoT integration, require focused attention.
