PCB Statistics

The following statistics reflect the Wangling WL-CT350 PCB’s design complexity and component compatibility, highlighting its suitability for compact, high-performance electronic assemblies.

Core Material: WL-CT350 High-Frequency Laminate

At the heart of the WL-CT350 PCB is Wangling’s WL-CT350 organic polymer ceramic fiberglass cloth-coveredcopper clad laminate—a thermosetting resin-based material tailored for high-frequency applications. Composed of hydrocarbon resin, ceramics, and fiberglass cloth, this laminate offers a compelling alternative to foreign counterparts and traditional materials like PTFE. Unlike PTFE, which requires complex processing, the WL-CT350 material can be processed using techniques similar to standard FR4, simplifying manufacturing while ensuring superior circuitry stability and consistency.

The unique blend of hydrocarbon resin and composite ceramics endows the material with a suite of high-performance characteristics: low loss, exceptional high-temperature resistance, and outstanding temperature stability. With a glass transition temperature (TG) exceeding 280°C, a stable dielectric constant (Dk) and loss temperature coefficient, and a low thermal expansion coefficient, the WL-CT350 laminate ensures reliable operation even in harsh environmental conditions. These properties make the WL-CT350 PCB particularly well-suited for high-frequency designs where signal degradation and thermal stress are major concerns.
