Kinji's 12-Layer 3-Step HDI Board Powers Industrial Intelligence Advancement

In high-end fields such as industrial control, edge computing, precision testing, and industrial communications, equipment demands extreme stability, high integration, and superior high-speed transmission performance. As the core interconnect carrier for industrial intelligent devices, the PCB forms the foundation for stable system operation, directly determining the performance ceiling and service life of end products. Addressing the critical industry needs for miniaturization, high computing power, heavy loads, and long-term stable operation in industrial equipment, Kinji proudly introduces its 12-layer 3-step HDI board. Leveraging cutting-edge precision processes and stringent industrial-grade quality control, this solution delivers high-density, high-speed, and high-reliability interconnection, comprehensively breaking through the performance limitations of traditional PCBs and empowering the iterative upgrade of advanced industrial intelligent equipment.

Advanced Process Iteration Builds the Core Foundation for High-Density Interconnection

Kinji's 12-layer 3-step HDI board employs mainstream high-order build-up manufacturing processes, integrating blind and buried via technologies with micro-via precision integration. This thoroughly overcomes the constraints of traditional PCBs in terms of routing space and layer count. Within the ultra-compact dimensions of a 1.2mm ultra-thin profile, it achieves orderly layering and efficient interconnection across 12 layers, effectively eliminating Stub interference in high-speed signal transmission. This establishes a low-loss, low-crosstalk, and high-consistency high-frequency transmission channel, perfectly matching the stringent demands of high-end industrial equipment for high-speed, real-time data exchange.

Micron-Level Precision Routing for High-Density Fine-Pitch Packaging

The product achieves industry-leading hair-thin routing precision, with a minimum via diameter of 0.2mm and line width/spacing precisely controlled to 2.95/3.54 mil. This fully accommodates high-density precision component packaging such as BGA, QFN, and μBGA. The complex multi-layer circuit layout is organized and orderly, effectively resolving design challenges associated with high integration and miniaturization in industrial equipment, providing robust process support for lighter, more integrated end products.

Gradient Copper Thickness Structure Balances Transmission Performance and Load Capacity

The inner layers utilize a differentiated gradient copper thickness design of 1/1/0.5/0.5 oz, while the outer layer finished copper thickness is stably maintained at 1.0 oz. This scientifically designed layer-by-layer copper thickness ratio balances high-speed signal transmission with high-current load requirements. It not only ensures low-loss, high-purity transmission of high-frequency signals but also significantly enhances the high-current carrying capacity of power and ground layers. Simultaneously, it optimizes the overall heat dissipation structure, comprehensively safeguarding long-term, high-load, uninterrupted stable operation of the equipment.

Stringent Material Selection Forges an Industrial-Grade Reliable Protection System

Industrial environments are frequently subjected to harsh conditions such as high-low temperature cycling, high humidity, dust accumulation, and high-frequency vibration. The stability of board materials and processes is paramount for long-term equipment reliability. Kinji adheres to industrial-grade quality standards, implementing strict process control from substrate selection to surface finishing, comprehensively enhancing the board's environmental adaptability and building a robust defense line for reliable terminal equipment operation.

· Optimized Substrate Material: Utilizes Shengyi S1000-2M industrial-grade high-performance laminate, featuring an ultra-high Tg of 170°C and an ultra-low coefficient of thermal expansion. This effectively resists board deformation, delamination, and cracking caused by extreme temperature variations. The product exhibits excellent through-hole reliability, outstanding resistance to CAF (Conductive Anodic Filament) penetration, and superior resistance to moisture, heat, aging, and corrosion compared to standard materials, readily coping with various harsh industrial environments. Additionally, the use of lead-free FR-4 environmentally friendly material complies with green production regulations, while maintaining excellent mechanical processability to ensure high yield rates and consistent quality in mass production.

· Surface Finish: Employs an immersion gold process, forming a uniform and dense nickel-gold composite protective layer. On one hand, this significantly improves board surface flatness, thoroughly eliminating the "dog-bone effect" associated with traditional HASL (Hot Air Solder Leveling) processes. It provides a flat and reliable soldering base for fine-pitch precision components, effectively reducing risks of poor soldering such as cold joints, empty joints, and solder skips. On the other hand, the chemically stable gold layer endows pads with excellent oxidation resistance, corrosion resistance, and anti-sulfurization properties, significantly extending board storage life and overall equipment service life, ensuring consistent soldering performance and stable connections during years of industrial operation.
