عالي التردد مضمن ثنائي الفينيل متعدد الكلور: Ultimate Solution for 5G Communication

As 5G communication, رادار الموجة المليمترية, and high-speed data transmission sweep the globe, standard circuit boards can no longer meet the demands of high-frequency signal transmission. When signal frequencies enter the GHz range, أ ثنائي الفينيل متعدد الكلور‘s material and structure directly determine the device’s performance ceiling.

اليوم, UGPCB presents a flagship product designed for complex communication environments: ال عالي التردد مضمن ثنائي الفينيل متعدد الكلور. This is not merely a لوحة الدائرة. It represents an industrial artwork that resolves the conflict between heat dissipation and signal integrity.

1. Product Definition

أ عالي التردد مضمن ثنائي الفينيل متعدد الكلور combines high-frequency materials like Rogers RO4003C with copper base materials using specific prepregs such as 4450f. The copper section embeds into the ثنائي الفينيل متعدد الكلور‘s specific layers through hybrid lamination.

This technology perfectly merges the metal base’s excellent heat dissipation with the low-loss characteristics of high-frequency materials through an embedded structure. It specifically addresses thermal management challenges in high-power, high-frequency scenarios.

2. Core Parameters and Design Considerations

A superior عالي التردد ثنائي الفينيل متعدد الكلور requires precise design and material selection. Consider UGPCB’s typical 4-layer board:

اعتبارات التصميم الحرجة

When designing such high-frequency ثنائي الفينيل متعدد الكلور متعدد الطبقات, دقيق التحكم في المعاوقة is essential. You must maintain continuous characteristic impedance, typically 50Ω single-ended or 100Ω differential. علاوة على ذلك, managing gap filling between the embedded copper block and dielectric layers using 4450f’s resin flow prevents delamination.

3. Working Principle and Performance Advantages

مبدأ العمل

The device operates through electromagnetic and thermal dynamics coordination. High-frequency signals travel through RO4003C (Dk=3.38) with minimal loss. Meanwhile, heat from power amplifiers conducts rapidly through vias or direct contact to the embedded copper base. This copper acts as a thermal “highway” with its high thermal conductivity of approximately 398 W/m·K, spreading heat quickly to external sinks.

Core Performance Features

1. Superior Signal Integrity: Rogers RO4003C maintains stable dielectric constant up to 10GHz and beyond. Compared to standard FR-4, signal loss reduces significantly.

2. Revolutionary Heat Dissipation: The embedded copper structure positions cooling directly inside the ثنائي الفينيل متعدد الكلور. Thermal paths become shorter than traditional metal-base boards, improving cooling efficiency by over 50% and eliminating local hotspots in dense layouts.

3. Excellent Thermal-Mechanical Stability: RO4003C and copper base show optimized CTE matching. Combined with 4450f’s adhesive toughness, this ensures reliability through -40°C to +125°C thermal cycling.

4. Scientific Classification

Within UGPCB’s product system, this item falls under these specialized categories:

• By Material: عالية التردد Hybrid Laminate PCB

• By Structure: Embedded Metal Core PCB (also called Copper Inlay PCB)

• By Process: Multilayer Buried Copper Block PCB

5. Material and Structure Analysis

• روجرز RO4003C: A hydrocarbon ceramic-filled laminate. It stands as the “gold standard” for high-frequency applications, guaranteeing low-loss transmission.

• 4450f Prepreg: The RO4000 series bonding material. It offers excellent flow and filling properties, bonding RO4003C with the copper base and ensuring interlayer adhesion.

• Embedded Copper Base: Typically uses T2 copper. Precision machining shapes it for embedding inside the ثنائي الفينيل متعدد الكلور, serving as the primary cooling channel.

• لمسة نهائية ذهبية غامرة: The thick gold layer with dense nickel underneath protects circuits. It also provides excellent surface conductivity, essential for high-frequency skin effects.

6. Manufacturing Process Revealed

Creating this embedded copper PCB requires mastering three critical processes:

1. Cavity Creation: Use controlled-depth routing to mill precise cavities in the multilayer board after initial lamination.

2. Copper Block Embedding: Place treated copper blocks into cavities. Allow 4450f resin to fill gaps during pressing.

3. Secondary Lamination: Apply high temperature and pressure. Ensure void-free bonding between copper, dielectric, and circuit layers without delamination.

7. Typical Applications

• Communication Equipment PCB: 5G base station power amplifiers, microwave backhaul modules.

• إلكترونيات السيارات: Millimeter-wave radar (77GHz), LiDAR driver boards.

• الفضاء: Satellite communication components, phased array radar systems.
