1.18-Layer Megtron-7 Rigid PCB Обзор продукта & Определение

This product is an 18-layer rigid high-layer count PCB with a precisely controlled thickness of 1.86мм and overall dimensions of 165mm x 120mm. It utilizes industry-leading Megtron-7 high-speed low-loss laminate and features a 2-microinch (approx. 0.05мкм) Химическое никель, иммерсионное золото (СОГЛАШАТЬСЯ) обработка поверхности. This specification represents an advanced tier in высокопроизводительный Производство печатных плат, designed for applications where signal integrity, тепловое управление, and reliability are paramount.

2. Критические соображения дизайна

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, power, and ground planes to ensure stable power distribution and clear signal return paths.

2. Контроль импеданса: High-speed signal transmission demands precise controlled impedance PCB дизайн. Trace width and spacing must be calculated accurately based on the Dk (Диэлектрическая проницаемость) и Дф (Коэффициент рассеяния) of Megtron-7. We offer professional impedance calculation and simulation services.

3. Тепловое управление: 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. Взаимодействие высокой плотности (ИЧР) 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. Как это работает & Структура

А Многослойная печатная плата 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. Этот 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.
