Choosing a PCB materials for high-frequency applications
Choosing a PCB materials for high-frequency printed-circuit board (PCB) is generally a compromise, often between price and performance. But PCB materials are also selected by two key factors:
How well they meet the needs of an end-use applications.
What kind of effort is required to fabricate a desired circuit with a particular materials.
These two are generally a challenging factors among the customer and their needs.
