WL-CT350 Material Introduction

Wangling's WL-CT350 organic polymer ceramic fiberglass cloth-covered copper clad laminates are a thermosetting resin-based high-frequency materials. The composition of the dielectric layer includes hydrocarbon resin, ceramics, and fiberglass cloth. It exhibits low loss performance, meeting the requirements for high-frequency designs. PCB processing can be carried out using techniques similar to FR4 materials, making it simpler compared to PTFE materials and ensuring better stability and consistency in circuitry. It can be used as a substitute for similar foreign products.

The combination of hydrocarbon resin and composite ceramics provides excellent low loss, high-temperature resistance, and temperature stability characteristics. The series of materials have a stable temperature coefficient of dielectric constant and loss, low thermal expansion coefficient, and a high TG value of above 280°C.
