Questions & Answers

Q: How does Rogers Radix™ enable the creation of low-K substrates with complex structures that foam cannot achieve?

Rogers Radix™ allows the printing of low-K substrates with complex structures by providing a printable resin material that can be used to create structural rigidity and even incorporate plated through holes directly into the substrate, which is not possible with traditional foam materials.

Q: What is the role of Fortify's continuous kinetic mixing (CKM) technology in maintaining the homogeneity of the resin material during the printing process?

Fortify's CKM technology circulates, mixes, and heats the resin throughout the printing process, preventing settling of any fiber additives and ensuring a consistent and homogeneous mixture, resulting in high-quality printed parts.

Q: How does Radix enable the printing of gradient index structures like the Luneburg lens for antenna applications?

Radix allows for the printing of gradient index structures by providing a resin material with a variable dielectric constant. The Luneburg lens, for example, starts with a dielectric constant of 2 at the center and gradually decreases to 1 at the outside, allowing for antenna steering by changing the feeding point.

Q: How does Radix enable the incorporation of 3D metallization in antenna components?

Radix provides a resin material that allows for the direct printing of pure copper on the surface, eliminating the need for a separate metallization step. This enables the creation of antenna components that can be directly mounted to surfaces with metallization, improving performance and simplifying the manufacturing process.
