(Printed

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
