What Makes the TP440-Based 2-Layer Rigid PCB Ideal for Beidou, Fuze, and Miniaturized Antennas?

Product Overview

A newly shipped, high-performance 2-layer rigid printed circuit board has been developed for demanding high-frequency and aerospace-grade applications. This PCB has been fabricated using the TP440 laminate from the Wangling TP Series, a unique high-frequency thermoplastic material. The dielectric layer of the TP440 is composed of ceramic and polyphenylene oxide (PPO) resin, and no fiberglass reinforcement has been included. By adjusting the ratio between ceramic and PPO resin, a precise and stable dielectric constant of 4.4 has been achieved. Excellent dielectric performance and high reliability are provided.

The finished PCB is classified as a 2-layer rigid board, and 100% electrical testing has been performed prior to shipment. Worldwide availability has been ensured.

Processing & Handling Notes (to be observed)

Fabrication Ease: The material can be easily machined (drilling, turning, grinding, shearing, etching), and a high yield is typically achieved. Processing cost is significantly reduced compared to ceramic substrates.

Multilayer Boards: Multilayer processing is generally not recommended. If attempted, low-temperature bonding sheets must be selected, and feasibility should be carefully evaluated.

Soldering Restrictions:

260°C thermal shock testing is not suitable for this material.

Wave soldering should be avoided.

Hand soldering with a constant-temperature iron is recommended.

Reflow soldering is generally not advised. If reflow soldering must be performed, a maximum set temperature of 200°C should not be exceeded, and full feasibility validation is required.

Typical Applications

The TP440-based PCB has been identified as an ideal solution for the following applications:

• GPS / GNSS antennas
• Beidou navigation systems
• Missile-borne electronics
• Fuze systems
• Miniaturized antennas
• High-reliability RF circuits

Compliance & Testing

All typical laminate data have been obtained using GB/T 12636-1990 or IPC-TM-650 (2.5.5.5 stripline method for Dk) and IPC-TM-650 or GBT4722-2017 for other properties. The finished PCB has been manufactured and tested to IPC-Class-2 standards. The Immersion Gold surface finish supports lead-free (RoHS) assembly processes.

It should be noted that all test data are typical measurement values intended to aid material selection. No express or implied warranty is constituted, nor is it ensured that all performance characteristics will be met in every specific application. Suitability for a particular use case must be independently verified by the customer.

Ordering Information
