IsoClad 933 High Frequency PCB
Introduction
Rogers IsoClad 933 laminates are composites made of non-woven
fiberglass and PTFE, designed for use as PCB substrates. They
feature a higher ratio of non-woven fiberglass to PTFE, resulting
in a more reinforced material that provides superior dimensional
stability and enhanced mechanical strength.
Its unique non-woven reinforcement structure provides flexibility,
making it an ideal choice for applications where circuit
conformability is essential. The use of longer random fibers and a
proprietary manufacturing process ensures exceptional dimensional
stability and improved mechanical strength, setting it apart from
traditional woven fiberglass laminates.
Features
The IsoClad 933 laminate boasts a low dielectric constant (Dk) of
2.33 at 10 GHz and 23°C, ensuring minimal signal loss and optimal
integrity.
Its dissipation factor is just 0.0016 at the same frequency and
temperature, which significantly reduces energy loss, making it
ideal for high-frequency circuits.
Additionally, it offers impressive peel strength of 10 lbs per
inch, ensuring strong mechanical adhesion.
IsoClad 933 also exhibits highly isotropic properties, performing
uniformly across the X, Y, and Z axes for reliable and predictable
behavior in all directions.
Other notable features include low water absorption (0.05%),
minimal outgassing (0.03% TML, 0 CVCM, 0.02% WVR), and excellent Dk
uniformity, guaranteeing consistent performance throughout its use.
PCB Capabilities
The IsoClad 933 PCB offers a wide range of customization options to
meet diverse design requirements. It supports double-sided,
multilayer, and hybrid PCB configurations, providing flexibility
for various circuit designs.
The laminate is available with different copper weight options,
including 1oz (35µm) and 2oz (70µm), allowing designers to tailor
conductivity and power handling capabilities to their specific
needs.
Additionally, multiple dielectric thickness options are available,
such as 15 mils (0.381mm), 31 mils (0.787mm), and 62 mils
(1.575mm), enabling precise control over electrical properties and
board thickness.
The PCBs can accommodate dimensions of up to 400mm x 500mm,
offering ample space for complex circuitry and components.
For visual customization, a variety of solder mask colors are
available, including green, black, blue, yellow, and red.
The boards can also be finished with a range of surface treatments,
such as immersion gold, HASL, immersion silver, immersion tin, OSP,
bare copper, pure gold, and ENEPIG.
Applications
IsoClad 933 PCB is ideally suited for a variety of high-frequency
and high-reliability applications. It is widely used in conformal
antennas, where its flexibility and stable electrical properties
are critical. The material is also an excellent choice for
stripline and microstrip circuits, which require precise control
over signal integrity.
Additionally, it is employed in advanced guidance systems, radar
systems, and electronic warfare systems, where its low loss and
high performance are essential for mission-critical operations.
