In the era of high-speed data transfer and precision computing, the performance of the 인쇄 회로 기판 (PCB)—the core brain of electronic devices—determines the entire system’s capability. UGPCB introduces its high-performance 18-레이어 견고한 PCB 기반으로 Megtron-7 재료, engineered to meet the most demanding electrical and physical challenges, serving as the essential foundation for your next-generation advanced equipment.
1.18-Layer Megtron-7 Rigid PCB 제품개요 & 정의
This product is an 18-layer rigid high-layer count PCB with a precisely controlled thickness of 1.86mm and overall dimensions of 165mm x 120mm. It utilizes industry-leading Megtron-7 high-speed low-loss laminate and features a 2-microinch (대략. 0.05μm) 무전해 니켈 침지 금 (동의하다) 표면 마감. This specification represents an advanced tier in 고성능 PCB 제조, designed for applications where signal integrity, 열 관리, and reliability are paramount.

2. 중요한 설계 고려 사항
Designing a successful 18-layer PCB, especially with high-speed materials like Megtron-7, requires careful attention to several core aspects:
-
Stack-up Design: A rational layer stack-up is critical for impedance control and crosstalk reduction. A typical 18-layer stack includes multiple signal, 힘, and ground planes to ensure stable power distribution and clear signal return paths.
-
임피던스 제어: High-speed signal transmission demands precise controlled impedance PCB 설계. Trace width and spacing must be calculated accurately based on the Dk (유전 상수) 및 Df (소산 인자) of Megtron-7. We offer professional impedance calculation and simulation services.
-
열 관리: The 1.86mm board thickness and multi-layer structure necessitate effective thermal pathways in the design, such as using thermal vias to connect internal copper layers for efficient heat dissipation from components.
-
고밀도 상호 연결 (HDI) Considerations: While this is a standard through-hole design, careful planning of via types (blind, 매장, through-hole) is essential at this layer count to minimize stub effects and optimize signal paths.
3. 작동 방식 & 구조
에이 다층 PCB functions like a highly integrated, three-dimensional “road network.” Electrical signals travel on copper traces (“roads”) on the surface and internal layers, with vertical connections between layers established through plated through-holes (“interchanges”). Dedicated power and ground planes provide stable voltage reference and noise shielding for the entire system. 이것 18-레이어 견고한 PCB is formed through a precise lamination process, bonding multiple core layers and prepreg sheets into a single, robust unit with excellent electrical properties. Its sophisticated PCB board structure is the foundation for implementing complex circuit functionalities.
