Роджерс 4003 PCB Product Deep Dive: Определение, Properties, Приложения & Производственный процесс

1. Обзор продукта: What is Rogers 4003 печатная плата?

The Роджерс 4003 печатная плата is a high-performance printed circuit board manufactured using Rogers Corporation’s RO4003C™ laminate material. This product belongs to the RO4000® series hydrocarbon-ceramic composite material family. Manufacturers design this печатная плата specifically for high-frequency RF circuits, microwave circuits, and high-speed digital systems. It offers industry-leading low dielectric constant, low loss properties, и превосходная термическая стабильность.

Rogers Corporation developed the patented RO4003C™ material technology. This material is a hydrocarbon resin system enhanced with ceramic filler particles and reinforced with woven glass fabric. The electrical performance of this material system matches traditional PTFE/woven glass materials. Однако, the processing method works with standard epoxy/woven glass (ФР-4) Производство печатных плат процессы. This eliminates the need for special via pretreatment or sodium etching, which significantly reduces manufacturing costs.

RO4003C laminate complies with IPC-4103 standard, Slash Sheet /10 clause. This classification covers laminate base material specifications for high-speed/high-frequency applications. Within the IPC standard system, МПК-4103 applies specifically to high-speed/high-frequency copper-clad laminate base material specifications. IPC-4104 covers межсоединение высокой плотности (ИЧР) and microvia material requirements.

This product uses a stackup structure of RO4003C (основной) + РО4450F (prepreg/bonding layer). This forms a high-reliability многослойная плата configuration. It works especially well for high-density interconnect high-performance RF and microwave modules.

2. Product Definition and Core Specifications

UGPCB’s Rogers 4003 PCB uses the following precise configuration parameters:

Test Method Reference: ИПК-ТМ-650 2.5.5.5 (Stripline method), measured @10GHz/23°C.

3. Рекомендации по проектированию

Engineers must focus on these key points when designing Rogers 4003 печатная плата:

Контроль импеданса Дизайн: RO4003C has a tightly controlled dielectric constant of Dk=3.38±0.05 at 10 ГГц. This tolerance ensures impedance consistency within ±5%, greatly improving RF matching network and transmission line design accuracy.

Copper Thickness Selection: This configuration starts with 17μm (0.5 унция) base copper thickness. The finished copper thickness reaches 1 унция (35мкм) through electroplating. Matching Z-axis copper and dielectric CTE is crucial for multilayer board via reliability.

Line/Space Capability: The minimum trace width and spacing of 6mil/6mil is a baseline for signal integrity and design for manufacturability (DFM). High-density interconnect designs can go further to 4mil/4mil depending on equipment capabilities.

Multilayer Configuration: Using RO4450F as the bonding material between core layers provides better flow than RO4450B, making it the preferred choice for new designs. RO4450F has a Z-axis CTE range of 43–60 ppm/°C, ensuring plated through-hole reliability under thermal cycling.

Solder Mask and Surface Finish: Use high-quality photoimageable solder mask ink with ENIG surface finish. This provides solderability protection, стойкость к окислению, and prevents copper surface contamination.

4. Working Principle and Electrical Mechanism

The high-frequency working principle of Rogers 4003 PCB relies on the material’s low dielectric constant (Дк) и низкий коэффициент рассеяния (Дф / tan δ).

Signal Propagation Speed (Vp) Calculation:

Vp = c / √Dk

Где:

• c = speed of light ≈ 3×10⁸ m/s

• Dk = dielectric constant = 3.38

• Vp ≈ c / √3.38 ≈ c / 1.838 ≈ 1.63×10⁸ m/s ≈ 163 mm/ns

Compared to typical Материал ФР-4 (Dk ≈ 4.2–4.8, according to IPC-4101E, @1MHz Dk range 4.2-4.8), RO4003C reduces the dielectric constant by approximately 20%–30%. This significantly increases signal transmission speed and reduces propagation delay.

Signal Loss Mechanism:
Insertion loss (IL) consists of dielectric loss and conductor loss:

• Dielectric loss relates to Dk and Df: αd ≈ k·f·√Dk·Df

• RO4003C has a very low loss factor of Df=0.0027 at 10 ГГц, far lower than the typical FR-4 value (≈0.018–0.020)

• This superior loss performance ensures high signal fidelity in the GHz frequency range

Thermal Management Performance:
Thermal conductivity k = 0.71 W/m · k, better than traditional FR-4 (приблизительно. 0.25 W/m · k). This helps power amplifiers and RF front-end modules dissipate heat effectively.

5. Product Scientific Classification

Based on international industry standards and material properties, this product fits into the following scientific classification categories:

This classification system provides accurate identification for supply chain management, quality evaluation, and application selection.
