Ultra-Thin 0.30mm High-Frequency PCB | 2-Layer Rogers R04003 Board with ENIG | UGPCB

Ultra-Thin High-Frequency PCB: 0.30mm Thick 2-Layer Rogers R04003 Product Overview & Definition

This Ultra-Thin High-Frequency PCB from UGPCB is a double-sided printed circuit board manufactured using Rogers R04003 high-frequency laminate. Engineered for electronic devices with stringent demands on size, weight, and RF performance, this board excels in radio frequency (RF), microwave communication, and high-speed digital applications. Its core advantage lies in the combination of an extremely thin profile (0.30mm) and superior dielectric properties, making it a critical component for device miniaturization and enhanced performance.

Technical Specifications & Classification

• Classification: High-Frequency/Microwave PCB, Ultra-Thin PCB

• Layers: 2 Layers (Double-Sided PCB)

• Board Thickness: 0.30 mm

• Base Material: Rogers R04003 Laminate (0.2mm core, built up to final thickness)

• Copper Weight (Finished): 1oz / 1oz (approx. 35μm per side)

• Surface Finish: Electroless Nickel Immersion Gold (ENIG), 2μ”

• Dimensions: 124.45 mm x 39.69 mm

Materials & Performance Characteristics

• Laminate: Rogers RO4003C laminate is used, featuring a stable dielectric constant (Dk ~3.0) and a very low dissipation factor (Df). This is essential for high-frequency circuit boards to minimize signal loss and ensure signal integrity.

• Copper Foil: Standard 1oz (35μm) electro-deposited copper, offering excellent conductivity and current-carrying capacity.

• Surface Finish: ENIG (2μ”) provides a flat, solderable, and oxidation-resistant surface. The thin gold layer is particularly suitable for RF and microwave PCBs, minimizing signal attenuation due to the skin effect at high frequencies.

Structure, Design & Manufacturing Key Points

1. Structure: Standard 2-layer board structure with plated through-holes (PTH) for inter-layer connectivity.

2. Critical Design Considerations:

   • Impedance Control: Precise controlled impedance PCB design is crucial. Trace width/spacing must be carefully calculated based on the Dk of RO4003 and the 0.30mm dielectric thickness to achieve target impedance values (e.g., 50Ω).

   • Thermal Management: The thin profile offers a short path for heat dissipation. Layout of high-power components must be planned accordingly.

   • Mechanical Handling: The 0.30mm thickness offers flexibility but requires careful handling and support during assembly to prevent bending or damage.

3. Production Process Flow:
   Material Preparation → Inner Layer Imaging → Lamination (RO4003 core with prepreg) → Drilling → Desmear & Electroless Copper Deposition → Outer Layer Imaging & Pattern Plating → Etching → Solder Mask Application → ENIG Surface Finish → Routing / Profiling to 124.45x39.69mm → Electrical Testing (Flying Probe) → Final Inspection & Packaging

How It Works & Key Features

A high-frequency PCB acts as a “highway” for signal transmission, ensuring minimal loss, distortion, and delay. The Rogers RO4003 material and precision impedance-controlled design are fundamental to this performance.

Key Product Features:

• Excellent High-Frequency Performance: The low-loss characteristics of RO4003 laminate enhance RF circuit efficiency and signal integrity.

• Extremely Thin and Lightweight: The 0.30mm thin core PCB profile saves critical space and aids in product lightweighting.

• High Reliability & Solderability: The ENIG finish ensures long-term shelf life, excellent solder joint reliability, and a flat surface for fine-pitch components.

• Precision Manufacturing: Fabricated to exact dimensions (124.45×39.69mm) for reliable integration into compact assemblies.

Primary Applications & Use Cases

This ultra-thin Rogers PCB is ideal for:

• RFID Modules: Antenna and circuit boards in compact readers.
