PCB ทองแดงฝังความถี่สูง: Ultimate Solution for 5G Communication

As 5G communication, เรดาร์คลื่นมิลลิเมตร, 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, อัน พีซีบี‘s material and structure directly determine the device’s performance ceiling.

วันนี้, UGPCB presents a flagship product designed for complex communication environments: ที่ PCB ทองแดงฝังความถี่สูง. This is not merely a แผงวงจร. It represents an industrial artwork that resolves the conflict between heat dissipation and signal integrity.

1. Product Definition

อัน PCB ทองแดงฝังความถี่สูง combines high-frequency materials like Rogers RO4003C with copper base materials using specific prepregs such as 4450f. The copper section embeds into the พีซีบี‘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 PCB ความถี่สูง requires precise design and material selection. Consider UGPCB’s typical 4-layer board:

ข้อควรพิจารณาการออกแบบที่สำคัญ

When designing such high-frequency PCB หลายชั้น, แม่นยำ การควบคุมความต้านทาน is essential. You must maintain continuous characteristic impedance, typically 50Ω single-ended or 100Ω differential. นอกจากนี้, managing gap filling between the embedded copper block and dielectric layers using 4450f’s resin flow prevents delamination.

3. Working Principle and Performance Advantages

หลักการทำงาน

The device operates through electromagnetic and thermal dynamics coordination. High-frequency signals travel through RO4003C (Dk=3.38) with minimal loss. ในขณะเดียวกัน, 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. ความสมบูรณ์ของสัญญาณที่เหนือกว่า: 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 พีซีบี. 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:

• โดยวัสดุ: High Frequency 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

• Rogers 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 พีซีบี, serving as the primary cooling channel.

• การแช่ทองเสร็จสิ้น: 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. การใช้งานทั่วไป

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

• อุปกรณ์อิเล็กทรอนิกส์ยานยนต์: Millimeter-wave radar (77กิกะเฮิรตซ์), LiDAR driver boards.

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