Ⅱ. What Is a Rogers PCB? Core Technology Essentials

A Rogers PCB is a printed circuit board manufactured using Rogers Corporation’s specialty high-frequency laminates. Compared to traditional PCBs, Rogers circuit boards offer superior performance in three key dimensions:

1. Low Dielectric Constant and Temperature Stability: Rogers PCB materials have a Dk range of 2.2 に 16 with an exceptionally low thermal coefficient of dielectric constant (TCDk). 例えば, RO4350B material has a Dk of 3.48 ±0.05, with a variation of less than 50 ppm/°C across the -50°C to 150°C temperature range. This ensures consistent signal transmission characteristics whether in polar low temperatures or equatorial high-temperature environments.

2. Ultra-Low Dissipation Factor: Rogers materials achieve a Df as low as 0.0004 (RT /デュロイドの場合 5880), far below conventional FR-4‘s 0.02. In 77GHz automotive radar applications, RO3003 material keeps signal attenuation to 1.3dB/inch for 5 mil laminates, significantly improving radar detection accuracy.

3. Excellent Thermo-Mechanical Stability: Rogers high-frequency PCBs combine low moisture absorption (<0.03% typical for PTFE-based materials) with good thermal conductivity (0.50–0.66 W/m·K typical for RO4000 series). This ensures stable performance even in humid and hot environments. In aerospace applications, their low outgassing characteristics meet the demanding requirements of vacuum environments.

Ⅳ. How Rogers PCBs Work at High Frequencies – The Source of Signal Integrity

The superior signal integrity of Rogers PCBs at high frequencies comes from the synergy between material properties and electromagnetic wave propagation principles.

誘電率 (DK) and Signal Propagation Speed

The speed of an electromagnetic wave in a dielectric medium is inversely proportional to the square root of the dielectric constant:

v = c / √εᵣ

where c is the speed of light in a vacuum (~3×10⁸ m/s) and εᵣ is the relative permittivity. For Rogers RT5880 (Dk≈2.2), the signal travels at 67% of the speed of light, significantly faster than the 49% achieved with ordinary FR-4 (Dk≈4.2). Faster propagation speeds mean shorter signal delays and higher data throughput.

Precise Characteristic Impedance Control

Characteristic impedance is a critical parameter in high-frequency circuit design. For a microstrip line, it is approximated by:

z₀= 87 / √(εᵣ + 1.41) ×ln(5.98h / (0.8w + t))

where h is the dielectric thickness, w はトレース幅です, Tは銅の厚さです. Rogers PCB materials provide exceptional Dk stability across the entire frequency range—for example, RO3003 maintains a Dk of 3.00 ±0.04 at 10GHz—and an extremely low TCDk (<50 ppm/°C). This stability is the foundation for achieving characteristic impedance control within ±5%.

損失係数 (Df) and Insertion Loss

Insertion loss increases with frequency and can be expressed as:

α = k × f × √εᵣ × tan δ

where tan δ is the dissipation factor, f is the operating frequency, k は定数です. At 77GHz, FR-4 (DF≈0.02) would exhibit insertion losses exceeding 20 db/inch, making signal transmission nearly impossible. 対照的に, RO3003 (Df≈0.0013) achieves an insertion loss of only 1.3dB/inch for 5 mil laminates, which is about 1/15th the attenuation of FR-4. This dramatic difference explains why Rogers PCBs are essential for millimeter-wave radar applications.

V. Broad Applications of Rogers PCBs in Cutting-Edge Fields

Thanks to their excellent high-frequency performance and reliability, Rogers PCBs are widely used in the most demanding technology sectors:

📡 5G Communications and Base Stations: Rogers PCBs are the core substrate material for 5G base station antenna feed networks, RFフロントエンドモジュール, and power amplifiers. The RO4000 series’ compatibility with FR-4 processes makes it the top choice for large-scale commercial 5G base stations. RO4835 provides ten times the oxidation resistance of RO4350B, making it dominant in outdoor base station antennas.

🚗 Automotive Electronics and ADAS: With the ADAS (Advanced Driver Assistance System) adoption rate in domestic passenger cars exceeding 61% で 2025, 77GHz millimeter-wave radar has created explosive growth in demand for high-frequency PCBs. Average high-frequency PCB usage per vehicle has quadrupled compared to traditional models, and the market for automotive high-frequency boards continues to grow at over 45% 毎年. RO3003, with its Dk of 3.00 ±0.04 and exceptional stability from -50°C to 150°C, has become the standard material for 77GHz automotive radar.

🛰️ Aerospace and Defense: Under extreme temperature variations and vacuum conditions, Rogers PCBs, with their low moisture absorption and excellent thermo-mechanical stability, are widely used in navigation systems, satellite communication modules, 軍用レーダー, and missile guidance systems. RT/デュロイド 6000 series materials exhibit a Dk variation of ≤±0.03 at 200°C, ensuring signal consistency throughout the aerospace product‘s entire lifecycle.

🔬 Medical Imaging Equipment: The precise handling of high-frequency signals in MRI and ultrasound diagnostic equipment depends on the stable dielectric constant and ultra-low loss characteristics of Rogers PCBs. The TMM series’ chemical resistance ensures long-term reliability in medical devices.

VI. Rogers PCB Structure and Hybrid Design

UGPCB provides complete Rogers PCB structure solutions, from single-layer to multi-layer designs, with extensive engineering experience in multi-layer hybrid laminates.

Hybrid Stackup – The Cost-Effective Choice

Rogers high-frequency materials cost approximately 5 に 15 times more than standard FR-4. In most volume production projects, UGPCB uses a hybrid Rogers + FR4 stackup solution. This approach ensures excellent RF signal transmission quality while optimizing overall manufacturing costs.

Common Hybrid Stackup Configurations:

1. Top-Layer Rogers + Bottom-Layer FR4 (2+N layers): The top 1–2 layers use Rogers high-frequency material for antennas or RF traces, while the remaining layers use FR4 for digital circuits and power distribution. This configuration is ideal for 5G Active Antenna Units (AAU) and millimeter-wave radar modules.

2. Middle-Layer Rogers Core + Outer FR4 Layers (N+Rogers+N layers): The Rogers material serves as the core signal layer, with FR4 protective layers on top and bottom. This configuration provides excellent rigidity, making it suitable for avionics equipment that requires mechanical strength.

3. Full Rogers Multilayer Boards: These are used only for extreme performance millimeter-wave applications (such as 77GHz phased array radar and 94GHz imaging radar) or high-end research prototypes.

Key Considerations for Hybrid Design:

Impedance Compensation Design: Using process-aware impedance modeling and TDR scans of process validation boards (PVB), we can build an accurate impedance prediction model and control impedance deviation after hybrid lamination to within ±3%.
Stackup Symmetry Principle: The multi-layer stackup must be symmetrical about the central plane. Materials and copper layers must be arranged symmetrically to avoid residual stress and board warpage after lamination.
CTE Matching Management: UGPCB carefully selects prepreg materials and optimizes lamination parameters—using a three-stage ramp heating profile with zone pressure compensation—to control the CTE difference between layers, keeping warpage below 30 µm/m.

VII. UGPCB Rogers PCB Manufacturing Process – Quality You Can Trust

UGPCB has a mature, complete Rogers PCB fabrication process. Each step is carefully designed and strictly controlled to ensure that every board meets the rigorous requirements of IPC-6012 Class 2 またはクラス 3.

1. Material Selection and Preprocessing

We precisely match the Rogers PCB material type (RO4003C, RO4350B, RO5880, 等) to each customer‘s design specifications for Dk, ボードの厚さ, copper weight, 等. All incoming materials undergo a 100% 目視検査. For PTFE-based Rogers materials, we perform plasma activation pretreatment to increase surface energy above 65 mn/m, ensuring excellent coating adhesion.

2. Inner Layer Circuit Fabrication

We use レーザー直接イメージング (LDI) 装置 to accurately transfer circuit patterns to the Rogers substrate, achieving line width/spacing accuracy down to 1.5 mil with a coefficient of variation as low as 2.8%. エッチング後, AOI equipment inspects for defects such as nicks and shorts.

3. Lamination – The Core Technology

Lamination is the most critical step for Rogers PCB performance and yield:

スタックアップ設計: We calculate precise stackup thicknesses based on impedance requirements and signal integrity simulations. We select the right prepreg between Rogers and FR4 layers to ensure strong interlayer bonding.
Lamination Parameter Control: A three-stage ramp-up heating profile (1.5℃/分) with zone pressure compensation ensures void-free lamination. We hold a constant temperature at 280°C for 30 minutes with increased edge pressure up to 0.3MPa.
Void and Warpage Control: A vacuum lamination environment and precise temperature/pressure control eliminate voids. Finished board warpage is held to below 30 µm/m, significantly better than the industry average of 80 µm/m.

4. Drilling and Plated Through-Hole (PTH) 金属化

Rogers ceramic-filled materials are hard, so we use diamond-coated drill bits with feed rates of 1.2–1.8 m/min. A step-drilling process minimizes burrs and edge chipping. Electroless copper deposition forms a uniform conductive layer on the hole wall, followed by electrolytic copper plating to build thickness.

5. Outer Layer Circuit and Surface Finish

We offer three surface finish options based on customer requirements:

同意する (エレクトロレスニッケルイマージョンゴールド): Excellent solderability and corrosion resistance.
浸漬シルバー: High conductivity and flatness for high-frequency signal transmission.
OSP (有機はんだ付け性防腐剤): Economical and environmentally friendly.

6. Final Fabrication, 検査, and Testing

インピーダンス試験: We use TDR (時間ドメイン反射測定) to scan each trace, ensuring a characteristic impedance deviation within ±5%.
電気テスト: We perform insulation resistance testing per IPC-TM-650 2.5.7 そして 100% 飛行プローブ試験.
信頼性の検証: We perform thermal stress testing (solder float, 288°C/10 seconds, 3 サイクル) per IPC-6012 Class 3 要件, with void count in hole wall sections limited to ≤1 per coupon.
微細断面分析: A metallographic cross-section microscope inspects hole wall copper thickness and integrity.
