High-Speed PCB Manufacturing Expert | 100Gbps+ Signal Integrity Solutions
Summary: Certified to IPC-6012E Class 3, we specialize in high-frequency, high-speed PCB manufacturing, supporting ultra-high-speed transmission requirements from 56Gbps PAM4 to 224Gbps. Utilizing ultra-low-loss substrates (Dk=3.0±0.05, Df≤0.002@10GHz) and stringent impedance control tolerance of ±3%, we address signal integrity challenges in 5G base stations, AI servers, and optical modules.

Core Process Technologies:
✅ Any-Layer HDI Interconnection: Laser blind vias ≤50μm, supporting high-density routing of over 20 layers.
✅ Precise Control of Differential Pairs: Line width/spacing of 0.075mm, skew ≤0.5ps/inch.
✅ Back-Drilling Stub Control: Stub length ≤8mil, reducing signal reflection by 86%.
✅ Hybrid Laminate Architecture: Combination of FR4 and Rogers RO4835, optimizing costs by 35%.

Key Performance Assurances:

Loss Control: Insertion loss ≤0.35dB/inch for 112G PAM4 signals @28GHz.
Thermal Enhancement: 2.0W/mK high-thermal-conductivity substrate, embedded copper blocks in chip areas (thermal resistance <0.8℃/W).
EMI Suppression: Optimized reference layer GND, near-end crosstalk ≤-50dB.

2025 Technology Upgrades:
▸ Introduction of 3D Lithography Technology: Achieving 2μm line width accuracy (supporting Chiplet packaging).
▸ Development of Terahertz-Grade Materials: Df≤0.0005@140GHz (pre-research for 6G communication).
▸ Application of AI Real-Time Impedance Compensation: Improving production yield to 99.2%.

Free Design Support:
Provide signal integrity simulation reports (HyperLynx/Polar SI9000), power integrity analysis, and DFM manufacturability reviews, mitigating 23 types of high-speed design risks (such as resonance/ground bounce noise). Support mass production of boards compliant with protocols like PCIe 6.0/USB4/802.3ck, with first samples delivered in as fast as 8 days.

✦ Certification Systems: IATF 16949 | ISO 13485 | UL94 V-0
✦ Featured Services: 56Gbps Eye Diagram Testing (sampling rate 256GSa/s) | Pre-certification for multi-board system-level electromagnetic compatibility.

FR4PCB.TECH Turnkey PCB Assembly Prototype & Mass Production Service

FR4PCB.TECH specializes in an integrated turnkey PCB assembly service that combines "prototyping + mass manufacturing," covering the entire process from "PCB fabrication (featuring core FR4 substrates and special substrates) + component procurement + SMT/DIP assembly + testing and debugging + finished product delivery." This approach sets us apart from services that focus solely on prototyping, single-phase mass assembly, or fragmented supply chain solutions.

Our key differentiators include: exclusive process advantages for FR4 substrates, seamless transition from prototyping to mass production, comprehensive supply chain management across the entire chain, customized adaptability (from R&D to volume production), and brand-level quality assurance.

Service scenarios: electronic R&D prototyping and validation, small-batch pilot production transition, medium-to-large-scale mass production delivery, suitable for a full range of applications including consumer electronics, industrial control, automotive electronics, medical devices, and IoT terminals.
