PCB printed circuit boards with radio frequency (RF PCBs) are an increasingly used technique within the PCB industry.
A RF-print is a pcb with a high frequency which works above 100 MHz.
Above 2 GHz radio frequency one speaks about a Microwave-pcb.
RF-pcb’s are used in different applications such as remote controls (wireless controls) security, smartphones, sensors etc.

New technologies make more and more use of these RF applications.
This asks for a manufacturing according to high quality standards and choosing the right RF-materials depending on the application.
It is important that one knows the properties of the various materials. Choosing the right material is perhaps the most critical decision in the production process of the RF-pcb.

The performance, manufacturability and cost of the pcb are here considerable affected.
