Evonik manufactures ROHACELL®, a lightweight structural foam used in antenna, RF, microwave, and other high-frequency applications.
ROHACELL® HF has a very low dielectric constant and favorable high-frequency transmission properties. Topline Circuit uses ROHACELL® as a dielectric spacer or structural core in antenna PCB assemblies and supports all available ROHACELL® HF grades.
ROHACELL® PCB Applications
Topline Circuit can manufacture ROHACELL® PCB structures for:
- Antenna PCBs
- RF PCBs
- Microwave PCBs
- Radar antenna systems
- Communication equipment
- Radome antenna assemblies
- Automotive radar systems
- Satellite communication systems
- Aerospace antenna systems
- Medical imaging equipment
Its fine, closed-cell structure helps limit resin absorption. It is compatible with metallic facing materials and supports designs that require low weight and stable high-frequency transmission.
ROHACELL® HF Materials
Topline Circuit supports:
- ROHACELL® 31 HF
- ROHACELL® 51 HF
- ROHACELL® 71 HF
Other ROHACELL® grades and thicknesses are also available according to the PCB design and application requirements.
