Introduction to IsoClad 933: A Superior Base Material
IsoClad 933 laminates are nonwoven fiberglass/PTFE composites designed specifically for use as printed circuit board substrates. What sets them apart is their nonwoven reinforcement, which makes them highly flexible. This flexibility allows the final circuit to be easily bent to shape, making them ideal for applications like conformal or "wrap-around" antennas.
Compared to competitive nonwoven fiberglass/PTFE laminates with similar dielectric constants, IsoClad 933 products use longer random fibers and a proprietary manufacturing process. This results in greater dimensional stability and better dielectric constant uniformity, ensuring consistent performance across the entire PCB.
Features of IsoClad 933: Performance at Its Best
- Dielectric Constant at 10GHz: 2.33, providing stable signal transmission in high-frequency applications.
- Dissipation Factor at 10GHz: 0.0016, minimizing energy loss and ensuring efficient power usage.
- Thermal Coefficient of DK: -132 ppm/°C, maintaining stable dielectric properties even with temperature fluctuations.
- Peel Strength: 10 lbs/inch, ensuring strong adhesion between the copper layers and the substrate, enhancing durability.
- Dielectric Breakdown: >45 kV, offering excellent insulation properties and protecting against electrical breakdown.
- CTE Values: X CTE at 31 ppm/°C, Y CTE at 35 ppm/°C, Z CTE at 203 ppm/°C, providing good thermal stability across different directions.
- Flammability: UL-94 V0 rating, ensuring the PCB is flame-retardant and safe for use in various environments.
Benefits of Choosing This PCB
- Less Rigid than Woven Fiberglass: The nonwoven nature of IsoClad 933 makes the PCB more flexible than those using woven fiberglass, allowing for bending and shaping without compromising performance.
- Highly Isotropic in X, Y and Z Directions: This isotropy ensures uniform performance across all directions, making the PCB reliable in complex circuit designs where signals travel in multiple directions.
Typical Applications
- Conformal Antennas
- Stripline and Microstrip Circuits
- Missile Guidance Systems
- Radar and Electronic Warfare Systems
