Liquid Crystalline Polymer

The R/flex® 3000 family of liquid crystalline polymer (LCP)-based circuit materials complements the R/flex 3600 LCP, single-clad laminate. The R/flex 3850® double-clad laminate offers a low dielectric constant (Dk = 2.9) for controlled impedance combined with good dimensional stability for dense fine-line applications. R/flex 3850 laminate is produced in a range of copper and film thicknesses, just as the single-clad laminate, and is available in standard panel formats. The R/flex 3000 family of materials now includes a single-clad lower melt point and a double-clad high melt temperature laminate. These materials offer a unique combination of mechanical, electrical, thermal and environmental properties for tightly controlled impedance flex interconnections, next-generation wireless handsets, high density flip-chip packages and moisture-resistant sensors.

High Resistivity Silicon

This HiRes™ is a high purity, high resistivity silicon for microwave and millimeter-wave applications. Wafers made from it can replace existing RF wafer substrates without compromising important parameters and make “one chip” solutions possible. It is a monocrystalline silicon grown by the Float Zone process with a bulk resistivity from 8000 Ω-cm to 30,000 Ω-cm. This silicon is available with both p and n-type dopants and has a narrow axial and radial resistivity tolerance to ensure uniform microwave performance. A material’s loss tangent (tanδ) is significant and HiRes silicon claims to exhibit values of tand far below those of low resistivity silicon.
