TP1600 PCB 31.49mil High DK16 Wangling Laminate Pure Gold Plating

TP1600 PCB 31.49mil High DK16 Wangling Laminate Pure Gold Plating

1. Overview 

The TP1600 PCB 31.49mil Pure Gold Plating is a specialized 2-layer rigid high-frequency PCB built onTP1600 dielectric copper-clad laminate. Unlike standard FR-4 or high-frequency materials with glass cloth, Wangling TP1600 uses a ceramic-reinforced polyphenylene oxide (PPO) thermoplastic matrix without fiberglass, enabling precise dielectric control, uniform electrical performance, and freedom from weave effects that degrade microwave signal integrity. The pure gold plating surface finish ensures ultra-low contact resistance, stable impedance, corrosion resistance, and compatibility with precision assembly.

This Wangling TP PCB is optimized for miniaturized antennas, resonant structures, RF/microwave filters, couplers, high-frequency sensors, and aerospace systems including Beidou navigation, satellite payloads, missile-borne equipment, and fuzes. It combines high Dk, ultra-low dissipation factor, mechanical workability, and cost efficiency, making it a superior alternative to pure alumina or aluminum nitride ceramic substrates in many high-reliability scenarios.

5. Core Advantages and Differentiators

5.1 Ultra-Stable High Dielectric Constant

TP1600 PCB substrate provides a nominal dielectric constant Dk = 16.0±0.32, tightly controlled via ceramic-to-PPO ratio adjustment. This enables significant circuit miniaturization while maintaining resonant performance ideal for compact antennas and resonant cavities.

5.2 Ultra-Low Dissipation Factor

With Df≈0.0012 at microwave frequencies, the material minimizes insertion loss and improves efficiency up to 10 GHz with little variation across frequency. This outperforms many general-purpose high-frequency substrates and approaches ceramic performance at lower cost.

5.3 No Glass Weave Effect

The absence of fiberglass cloth delivers a smooth, uniform dielectric layer, eliminating spatial Dk variation and signal scattering common in glass-reinforced materials. This is critical for high-yield, repeatable microwave performance.

5.4 Pure Gold Plating for High-Frequency Reliability

• Pure gold plating offers:
• Ultra-low and stable contact resistance
• Superior corrosion resistance in harsh environments
• Consistent impedance and low signal loss
• Excellent wire-bonding and fine-pitch assembly compatibility
• Compatibility with recommended hand soldering and low-temp reflow

5.5 Excellent Mechanical and Thermal Stability

• Z-axis CTE: ~45 ppm/°C
• TcDk:–43 ppm/°C, stable over temperature
• Long-term use:–100°C to +150°C
• Low outgassing and radiation resistance for aerospace
• Drillable, grindable, etchable–better manufacturability than ceramics

5.6 Process and Cost Advantages

Thermoplastic processability delivers higher yield and lower cost than alumina/AlN substrates. The Wangling PCB supports standard subtractive etching while avoiding the complexity of ceramic machining.

6. Recommended Assembly and Usage Constraints

To preserve performance and reliability, strict assembly rules apply:

• No wave soldering
• Reflow soldering max≤200°C; pretest feasibility
• Hand soldering recommended
• Avoid thermal shock above 180°C to prevent deformation or copper delamination
• Not recommended for standard multilayer lamination; use only low-Tg prepregs after review

7. Typical Target Applications

• Miniaturized high-frequency antennas and array elements
• RF/microwave filters, resonators, couplers, resonant cavities
• Aerospace, defense, satellite payloads, Beidou navigation
• Missile-borne systems, fuzes, and high-reliability sensors
• High-stability compact RF matching networks
