What is the Rogers RT/duroid® 6002 laminate?
RT/duroid® 6002 microwave material is the first low-loss, low dielectric constant laminate that provides superior electrical and mechanical properties, which are critical for designing mechanically robust and electrically stable complex microwave structures.
The thermal coefficient of the dielectric constant is extremely low over the temperature range from -55°C to +150°C (-67°F to 302°F), providing designers of filters, oscillators, and delay lines with the electrical stability required for today’s demanding applications.A low Z-axis coefficient of thermal expansion (CTE) ensures excellent reliability of plated through-holes. RT/duroid® 6002 materials have successfully undergone more than 5000 temperature cycles (-55°C to 125°C [-67°F to 257°F ]) without a single via failure.
Excellent dimensional stability (0.2 to 0.5 mils/inch) is achieved by matching the X and Y coefficients of thermal expansion to copper, often eliminating the need for double etching to achieve tight positional tolerances. The low tensile modulus in the X and Y directions significantly reduces stress on solder joints and allows the laminate’s expansion to be constrained by a minimal amount of low CTE metal (6 ppm/°C), further enhancing surface mount reliability.
