2026 HDI PCB Manufacturing Capability -Shenzhen Hongda Circuit Technology Co., Ltd.，
1. Evolution and Core Definition of 2026 HDI Technology
High Density Interconnect (HDI) PCBs serve as the vital electronic foundation for miniaturization, high integration, and high-speed signal transmission in modern devices. In 2026, driven by the surge in AI computing power and 6G communications, Shenzhen Hongda Circuit Technology Co., Ltd. has implemented a comprehensive upgrade across material systems, manufacturing processes, and structural design.
Our products feature ultra-fine circuit layouts and ultra-small micro-via designs. By utilizing 0.15mm high-precision buried vias and 0.02-0.075mm advanced laser blind vias, we ensure efficient and stable conduction for multi-layer circuits, meeting the extreme technical demands of 2026 high-end electronic equipment.
2. Structural Design: From 6+N+6 to Any layer Interconnection
Shenzhen Hongda Circuit Technology Co., Ltd. utilizes a high-precision symmetrical structure design, with mainstream 2026 specifications upgraded to 1+N+1, 2+N+2, 4+N+4, and the latest 6+N+6 multi-order structures.
- 6+N+6 High-Order Structure: This latest 2026 mainstream high-end architecture involves 6 cycles of laser drilling and high-precision lamination. With micro-via diameters ≤75μm, it is optimized for AI servers and 6G R&D.
- Any layer HDI (Arbitrary Layer Interconnection): As a core choice for the 2026 ultra-high-end market, this design abandons traditional buried vias in favor of ultra-fine laser blind vias. This allows free interconnection between any layers, significantly improving integration density and signal efficiency for quantum computing and aerospace electronics.
- Order Definition: The order of an HDI PCB is defined by the number of laser blind via manufacturing and lamination processes, with each stage requiring an independent high-precision lamination cycle.
3. Core Hole Filling and Material Technology for 2026
To meet the requirements of PCIe 6.0 and other high-speed protocols, Shenzhen Hongda Circuit Technology Co., Ltd. has established a sophisticated process matrix:
- High-Precision Electroplating Fill: Utilizing 2026-generation three-in-one horizontal equipment, we achieve high-density direct filling. Plating uniformity error is controlled within 5%, ensuring void-free vias with excellent thermal conductivity and mechanical strength.
- Customized Resin Plugging: For consumer electronics requiring extreme surface flatness, we offer low-dielectric loss epoxy resin filling followed by high-precision copper plating to ensure a dent-free finish.
- Elite Material Formulations: Our 2026 process utilizes M9-grade ultra-low loss copper clad laminates (Dk<3.0, Df<0.005) paired with HVLP5 ultra-thin copper foil and Q-cloth to minimize signal attenuation.
- Precision Control: Internal copper thickness is strictly controlled at 17.1μm, while interlayer alignment precision is maintained within ±10μm.
