Rugged Reliability for Microwave Systems - An AD1000 Q&A

Q: What makes AD1000 suitable for demanding radar and communications applications?

A: AD1000 delivers both robust mechanical properties and precision electrical performance thanks to its woven glass reinforcement and high dielectric constant composition. The glass weave provides superior dimensional stability and vibration resistance over traditional laminates.

Q: How does AD1000 enable circuit miniaturization?

A: Its high dielectric constant of 10.2 allows for tight spacing of components to reduce board footprint compared to lower Dk substrates. AD1000 also offers exceptionally low insertion losses up to Ku band and above through stable Dk properties.

Q: What thermal properties does AD1000 provide?

A: It has best-in-class thermal conductivity of 1 W/mK for efficient heat dissipation from dense designs. The tightly controlled CTE of 8-20 ppm/°C also ensures long-term reliability of surface mount and plated through-hole interconnects across all operating temperatures.

Q: Can you give an example application?

A: A recent X-band radar manifold incorporated 28 precision parts on a compact 59 mil 2-layer AD1000 board with 6-4 mil line/spacing. Even after vibration and thermal shock testing, it maintained its -30dB insertion loss target for aircraft collision avoidance systems.

Q: Is AD1000 suitable for other applications?

A: Yes, due to its dimensional stability, miniaturization and thermal robustness, AD1000 is well-suited for wireless backhaul, electronic warfare, aircraft surveillance and more. It enables revolutionary microwave system designs.

Q: How does the woven glass reinforcement benefit circuit design and manufacturing?

A: The weave provides greater dimensional stability and mechanical robustness compared to other laminates. This allows for tighter component spacing without risk of damage. It also permits larger panel sizes for multi-circuit processing to maximize productivity.

Q: What processing and design capabilities does AD1000 support?

A: Boards can be manufactured with line/spacing widths as tight as 6/4 mils. It accepts plated through holes as small as 0.35mm and up to 20 layers. Surface finishes include immersion silver and ENIG. The material is suitable for rigid, rigid-flex and flex circuits.

Q: Are there any environmental advantages?

A: Yes, AD1000's maximum moisture absorption of only 0.03% limits signal attenuation in high humidity applications. Its performance remains stable even after prolonged exposure to moisture. This makes it well-suited for both indoor and outdoor deployment in diverse climates.

Q: What industries are key adopters of AD1000 technology?

A: Aerospace, defense, satellite communication and Industrial IoT are major sectors leveraging AD1000 boards. Its strength and longevity enable mission-critical applications like air traffic monitoring, electronic warfare pods, 5G backhaul radios and automated factory sensors that demand peak reliability.
