Smartphones and mobile devices, holding a projected share of 29.3%, constitute the largest application segment in the global HDI PCB market. As smartphone designs evolve, manufacturers are required to cram more components into increasingly smaller form factors, pushing the limitations of conventional PCB technology. HDI PCBs enable this by incorporating microvias, blind and buried vias, and fine lines, dramatically increasing the interconnect density while reducing the overall footprint.

Apple’s iPhone 14 and 15 models utilize HDI PCBs with stacked microvia technology to support their ultra-compact designs and high-performance functionality. Suppliers like Zhen Ding Tech and Compeq Manufacturing (Taiwan) have provided high-layer-count HDI boards using FR4 for non-RF modules, while premium materials were reserved for RF-specific layers.

Moreover, the proliferation of 5G technology and advanced communication protocols in smartphones demands PCBs capable of supporting higher signal integrity and faster data transmission. HDI technology meets these stringent electrical performance requirements, ensuring stable and efficient operation of high-frequency, high-speed circuits essential for enhanced mobile experiences.

Additionally, the rising integration of multiple functionalities—such as high-resolution cameras, biometric sensors, augmented reality components, and power management modules—in a single device leads to complex multilayer PCB designs. HDI PCBs facilitate multi-layer stacking and complex routing, enabling the seamless integration of these features without significantly increasing device size or weight.

Impact of AI on the HDI PCB Market

The impact of Artificial Intelligence (AI) on the HDI PCB market is becoming increasingly profound, particularly in the areas of design automation, defect detection, and production optimization. AI algorithms are enabling faster and more accurate PCB layout and routing processes by predicting optimal paths, minimizing signal interference, and reducing layer count—leading to smaller, more efficient boards.

For instance, tools like Cadence Cerebrus AI are already being used in PCB design to automate and optimize electronic layouts for complex boards, including HDI PCBs used in smartphones and high-performance computing systems. These intelligent design systems not only reduce time-to-market but also minimize material usage and improve signal integrity, which are critical factors for HDI applications.
