Rogers RT/duroid 6002 is a groundbreaking microwave material that was the first to offer low loss and low dielectric constant, providing superior electrical and mechanical properties vital for the design of intricate microwave structures that are both mechanically reliable and electrically stable. Its thermal coefficient of dielectric constant is impressively low from -55℃ to +150℃, ensuring the electrical stability required by designers of filters, oscillators, and delay lines in today’s rigorous applications.
The material's low Z-axis coefficient of thermal expansion (CTE) guarantees excellent reliability for plated through holes, having successfully endured over 5,000 temperature cycles from -55℃ to 125℃ without any via failures.
Achieving excellent dimensional stability (0.2 to 0.5 mils/inch) is possible by aligning the X and Y coefficients of expansion with copper, often allowing for the elimination of double etching to secure tight positional tolerances. Its low tensile modulus (X,Y) significantly reduces stress on solder joints and permits minimal low CTE metal (6 ppm/℃) to effectively constrain laminate expansion, further boosting surface mount reliability.
RT/duroid 6002 is ideally suited for applications including antennas, complex multi-layer circuits with inter-layer connections, and microwave circuits designed for aerospace applications in demanding environments. |
