Rogers PCB Built on RT/Duroid 6002 10mil 0.254mm DK2.94 With Immersion Gold for Phased Array Antennas
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Rogers RT/duroid 6002 microwave material was the first low loss and low dielectric constant laminate to offer superior electrical and mechanical properties essential in designing complex microwave structures which are mechanically reliable and electrically stable.
The thermal coefficient of dielectric constant is extremely low from -55℃ to +150℃ which provides the designers of filters, oscillators and delay lines the electrical stability needed in 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 been successfully temperature cycled (-55℃ TO 125℃) for over 5000 cycles without a single via failure.
Excellent dimensional stability (0.2 to 0.5 mils/inch) is achieved by matching the X and Y coefficient of expansion to copper. This often eliminates double etching to achieve tight positional tolerances.
The low tensile modulus (X,Y) greatly reduces the stress applied to solder joints and allows the expansion of the laminate to be constrained by a minimum amount of low CTE metal (6 ppm/℃) further increasing surface mount reliability.
Applications particularly suited to the unique properties of RT/duroid 6002 material include flat and non-planar structures such antennas, complex mutli-layer circuits with inter-layer connections, and microwave circuits for aerospace designs in hostile environments.
Typical applications:
1. Airborne radar systems
2. Beam forming networks
3. Commercial airline collision avoidance
4. Global positioning systems antennas
5. Ground base systems
6. High reliability complex multi-layer circuits
7. Phased array antennas
8. Power backplanes
