IS620i is the first material in the digital products class built upon existing technologies, yet offering significant advantages for today’s digital world.

The resin matrix of IS620i is uniquely formulated for high-speed applications ranging from 2 to 15 GHz, and offers designers and fabricators the flexibility of digital design, the assurance of supply and the ease of conventional FR-4 processing. IS620i is the first material in its class to offer the complete
package of these critical features: low loss with a flat response over frequency, availability in both laminate and prepreg form in all typical thicknesses and sizes and the ability to use conventional
fabrication techniques.
