22 PCB Megtron-6 de alto rendimiento en capas | 2.0mm de espesor con acabado ENIG | De alta velocidad & Solución de RF – UGPCB

In the era of data-intensive and ultra-high-speed signal transmission, a Printed Circuit Board (tarjeta de circuito impreso) is far more than a simple component carrier; it is the critical architecture defining system performance limits. For demanding applications like high-speed networking, artificial intelligence computing, and advanced test instrumentation, standard FR-4 materials fall short. UGPCB addresses this need with our advanced 22-layer multilayer PCB built on Panasonic Megtron-6 R-5775G laminate, engineered to meet challenges of high frequency, low loss, and complex interconnectivity.

1.UGPCB’s 22-Layer Megtron-6 High-Speed PCB Descripción general del producto & Definición

Este producto es un 22-layer High-Density Interconnect (IDH) placa de circuito impreso rígida. Its core advantage lies in the use of a premium-grade, de alta velocidad, low-loss laminate—Panasonic’s Megtron-6 R-5775G. Combined with a robust 2.0mm board thickness and precision lamination technology, it creates a high-end interconnection platform capable of handling high-frequency signals above 10GHz with exceptional signal integrity and power integrity.

2. Consideraciones críticas de diseño

Designing such an advanced placa de circuito multicapa requires focus on:

1. Control de impedancia: Precise calculation and control of single-ended and differential impedance to ensure consistent signal propagation within the Megtron-6 dielectric.

2. Optimización de apilamiento: The intelligent arrangement of the 22 conductive layers (22capas)—including signal, fuerza, and ground planes—is crucial for maximizing shielding and minimizing crosstalk in this high-layer count PCB.

3. Gestión Térmica: The 2.0mm board thickness and multilayer structure aid heat distribution. Sin embargo, strategic use of thermal vias remains essential for high-power IC areas.

4. High-Frequency Routing: Employing microstrip or stripline configurations, avoiding acute angle turns, and leveraging the low-profile copper foil of Megtron-6 to reduce losses from skin effect.

3. How It Works & Estructura

A PCB’s primary function is to provide electrical connectivity and signal transmission between components via etched copper traces on an insulating substrate. Este 22-placa PCB de capa structure resembles a precise “multi-layer sandwich”:

• Capas internas: Use H/HOZ (aproximadamente 1/1 oz or 35µm) copper for core power, ground planes, and some internal signal routing.

• Capas exteriores: Use 1/1 oz copper for mounting primary components and routing critical signal traces.

• Dielectric Layers: All insulating prepreg materials are Panasonic Megtron-6 R-5775G, whose low Dielectric Constant (Dk) y factor de disipación (df) ensure superior high-speed signal transmission.

• Acabado superficial: Oro de inmersión de níquel químico (ACEPTAR) en 2 micro-inches (2tu”). This provides a flat, solderable surface, excellent oxidation resistance, and good wire-bonding capability, ideal for high-density BGA packages and RF connectors.

4. Material central: Panasonic Megtron-6 R-5775G

This is the heart of this advanced PCB material. Megtron-6 is Panasonic’s next-generation, de alta velocidad, low-loss circuit board material series.

• Key Performance: Features an extremely low Dielectric Constant (Dk~3.5) and ultra-low Dissipation Factor (Df~0.0015 @ 10GHz), significantly outperforming standard FR-4. Its high Glass Transition Temperature (tg) ensures superior thermal stability and dimensional consistency during high-temperature reflow soldering processes.

• Application Fit: Optimized for high-speed digital signals (10Gbps+ to 56/112Gbps) and millimeter-wave RF applications.
