🔍 FR4PCB.TECH: Expert in High-End HDI PCB Manufacturing | Microvia Technology · High-Density Interconnect · Automotive-Grade Reliability

FR4PCB.TECH specializes in the research and development and manufacturing of high-density interconnect (HDI) PCBs. Leveraging an Industry 4.0 smart factory and advanced FR4 substrate technology, we provide 2-32 layer precision HDI boards for 5G communication, medical electronics, automotive electronics, and other fields. Our capabilities include blind/buried vias, laser microvias (hole diameter ≥0.1mm), and Any-Layer interconnect designs, with minimum trace width/spacing down to 0.075mm.

💡 Technological Advantages and Core Competencies
Advanced Stack-Up Structures and Processes
Any-Layer Interconnect Technology: Supports complex stack-ups like 3+N+3 and 4+N+4, enabling high-density routing for 10+ layer boards. Blind/buried via accuracy of ±25μm ensures high-speed signal integrity.
Microvia Laser Drilling: Utilizes CO₂/UV laser systems for hole diameters ranging from 0.10-0.15mm, with annular rings ≤0.20mm, suitable for 0.4mm pitch BGAs and 01005 micro-component packaging.
Material and Reliability Assurance
Specialized Substrate Options: Offers standard FR4 (Tg ≥150°C) and high-frequency materials (Rogers/Taconic), supporting impedance control (±5% tolerance) and thermal management designs.
Military-Grade Quality: Certified to ISO standards, complying with IPC-6012/6016 specifications. X-ray inspection ensures void rates <5%, and flying probe testing achieves 100% connectivity verification.
Agile Services and Cost Optimization
Small-Batch Flexible Production: Accepts orders starting from 10 pieces, with 72-hour rapid prototyping. Supports one-stop HDI-PCBA services (design → SMT → testing).
Panelization and Stencil Optimization: Employs tab routing/V-cut panelization and standardized stencil designs to reduce small-batch costs by 30%.
🌐 Industry Applications and Differentiated Value
Medical Electronics: HDI boards for biosensors feature gold-finger interfaces, pass EN60601 safety certification, and offer ESD resistance >8kV.
Automotive Electronics: Rigid-flex HDI boards withstand temperatures from -40°C to 150°C, meeting AEC-Q100 automotive standards.
5G Communication: 20+ layer high-frequency HDI boards deliver a dielectric constant (Dk) of 4.2±0.1 @1GHz and insertion loss <0.5dB/inch.
