중요한 설계 고려 사항
Designing a 12-layer PCB requires meticulous attention to:
-
Stack-up Design: A rational stack-up sequence (예를 들어, alternating signal-ground-signal layers) is paramount for impedance control, crosstalk reduction, and Electromagnetic Compatibility (EMC). A proper 12-layer stack-up provides excellent power integrity and signal shielding.
-
임피던스 제어: For high-speed digital signals (예를 들어, DDR, PCIE) or RF lines, precise calculation and control of trace characteristic impedance (예를 들어, 50Ω 단일 종단, 90Ω/100Ω differential) are essential. We utilize advanced EDA tools and precise process controls to ensure consistency.
-
힘 & Ground Plane Management: Solid ground planes and optimized power segmentation ensure low-noise power delivery and clear return paths, which are critical for system stability.
-
열 관리: The 1.6mm board thickness and the thermal properties of FR-4 must align with component power dissipation. High-power areas may require thermal vias or integration with external cooling solutions.
작동 방식
A PCB is a passive platform that provides mechanical support, 전기적 상호 연결, and signal transmission pathways for electronic components. This 12-layer PCB facilitates a complete working system by connecting chips, 저항기, 커패시터, 등., through a complex network of etched copper traces. The multilayer architecture allows traces to cross on different layers without interference, significantly increasing circuit complexity and integration density. The ENIG surface finish guarantees reliable solder joints and long-term contact stability.

건설 & 재료
-
Layer Structure: 12 conductive copper layers laminated with insulating prepreg.
-
핵심 자료: FR-4 TU872SLK. This is a high-performance epoxy glass laminate offering advantages over standard FR-4:
-
Higher Thermal Stability (높은 Tg, typically ≥170°C), providing better resistance to thermal expansion.
-
Superior Electrical Properties, with stable Dielectric Constant (DK) 소산 인자 (Df) under high-temperature and high-frequency conditions.
-
Excellent CAF (Conductive Anodic Filament) Resistance, ideal for high-voltage, high-humidity environments, ensuring superior reliability.
-
-
완성된 두께: 1.60mm (nominal), with tight tolerance control (typically ±10%).
-
표면 마감: 무전해 니켈 침지 금 (동의하다). 니켈 두께: 3-5μm; 금 두께: 2 마이크로인치 (대략. 0.05μm). The gold layer protects the nickel from oxidation, providing a flat, 납땜 가능한 표면, while the nickel acts as a diffusion barrier between copper and gold.
주요 특징 & 성능
-
높은 신뢰성: TU872SLK high-Tg material and ENIG finish ensure resistance to high temperatures, 부식, and suitability for long-term operation in harsh environments.
-
우수한 신호 무결성: Rigorous stack-up design and impedance control guarantee high-speed signal quality and lower bit error rates.
-
Strong Load-Bearing & Thermal Capacity: The 1.6mm thickness offers robust mechanical strength and substantial thermal load management.
-
Precision Solder Platform: The flat 2μ” ENIG surface is ideal for fine-pitch 구성 요소 (예를 들어, BGAS), resulting in strong, reliable solder joints with low defect rates.
-
고밀도 상호 연결 (HDI): Twelve routing layers support complex, dense circuit designs, enabling reduced product footprint.
