1.18-Layer Megtron-7 Rigid PCB ภาพรวมผลิตภัณฑ์ & คำนิยาม

This product is an 18-layer rigid high-layer count PCB with a precisely controlled thickness of 1.86มม and overall dimensions of 165mm x 120mm. It utilizes industry-leading Megtron-7 high-speed low-loss laminate and features a 2-microinch (approx. 0.05µm) ทองคำแช่นิเกิลแบบไม่ใช้ไฟฟ้า (เห็นด้วย) พื้นผิวเสร็จสิ้น. This specification represents an advanced tier in ประสิทธิภาพสูง การผลิต PCB, designed for applications where signal integrity, การจัดการความร้อน, and reliability are paramount.

2. ข้อควรพิจารณาการออกแบบที่สำคัญ

Designing a successful 18-layer PCB, especially with high-speed materials like Megtron-7, requires careful attention to several core aspects:

1. Stack-up Design: A rational layer stack-up is critical for impedance control and crosstalk reduction. A typical 18-layer stack includes multiple signal, พลัง, and ground planes to ensure stable power distribution and clear signal return paths.

2. การควบคุมความต้านทาน: High-speed signal transmission demands precise controlled impedance PCB ออกแบบ. Trace width and spacing must be calculated accurately based on the Dk (ค่าคงที่ไดอิเล็กตริก) และดฟ (ปัจจัยการกระจาย) of Megtron-7. We offer professional impedance calculation and simulation services.

3. การจัดการความร้อน: 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.

4. การเชื่อมต่อระหว่างกันที่มีความหนาแน่นสูง (HDI) Considerations: While this is a standard through-hole design, careful planning of via types (blind, buried, through-hole) is essential at this layer count to minimize stub effects and optimize signal paths.

3. มันทำงานอย่างไร & โครงสร้าง

อัน multi-layer 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. นี้ 18-layer rigid 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.

4. วัสดุหลัก & Key Performance
