Rogers RT/duroid 6002 is a revolutionary microwave material, recognized as the first low loss and low dielectric constant laminate, essential for designing complex microwave structures that are both mechanically reliable and electrically stable. Its thermal coefficient of dielectric constant remains extremely low from -55℃ to +150℃, providing the electrical stability needed for filter, oscillator, and delay line designers in today’s demanding applications.
With a low Z-axis coefficient of thermal expansion (CTE), this material ensures reliable plated through holes, having successfully completed over 5,000 temperature cycles (-55℃ to 125℃) without any failures in vias.
The material achieves excellent dimensional stability (0.2 to 0.5 mils/inch) 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) reduces stress on solder joints and allows laminate expansion to be constrained by minimal low CTE metal (6 ppm/℃), enhancing surface mount reliability.
RT/duroid 6002 is particularly well-suited for applications that leverage its unique properties, including antennas, complex multi-layer circuits with inter-layer connections, and microwave circuits for aerospace applications in hostile environments. |
