Rogers RT/duroid 6002 is a pioneering microwave material known for its low loss and low dielectric constant, offering exceptional electrical and mechanical properties essential for creating complex and reliable microwave structures. Its thermal coefficient of dielectric constant remains remarkably stable from -55℃ to +150℃, providing the necessary electrical stability for designers of filters, oscillators, and delay lines in today's demanding applications.
The material features a low Z-axis coefficient of thermal expansion (CTE), ensuring the reliability of plated through holes. RT/duroid 6002 has successfully withstood over 5,000 temperature cycles (-55℃ to 125℃) without a single failure in vias.
Excellent dimensional stability (0.2 to 0.5 mils/inch) is achieved by aligning the X and Y coefficients of expansion with copper, often eliminating the need for double etching to achieve tight positional tolerances. Its low tensile modulus (X,Y) minimizes stress on solder joints and allows laminate expansion to be effectively managed by a minimal amount of low CTE metal (6 ppm/℃), thereby enhancing surface mount reliability.
RT/duroid 6002 is particularly well-suited for applications such as flat and non-planar structures, antennas, complex multi-layer circuits with inter-layer connections, and microwave circuits in aerospace designs operating in challenging environments.
