Description

Radio Frequency (RF) Rogers PCB Manufacturer

Radio Frequency PCB, short for RF PCB, is one of the fast-growing PCB technology in recent years, especially in satellite communication systems, military equipment, broadband access, and optical data networks areas. It is defined between 500 MHz and 2 GHz. The prototyping and volume production of RF PCB are two key process after design work is done.

RF PCB Design FAQ

In our experience with RF PCB designers or engineers, the most asked question is “How do I choose the correct laminate for particular project?” Whether out of cost consideration or performance, laminate selection makes a big impact. Below are a few guidelines for refrence:

1.Best Practices of Selecting Material for RF PCB

Similar Dielectric Constants: In RF PCB design, Non-uniform Dks in substrates may cause performance problems. Working with the PCB fabricator will ensure as close a Dk match as possible.
Similar Coefficient of Thermal Expansion (CTE): In RF PCB design, differing CTEs of the laminate substrates are likely to cause functional failures and reliability concerns. Therefore when choosing laminates, CTE needs to be ensured similarly.

Tight Substrate Bonding: How tightly substrate layers bond has a big impact on Dk. Working with the PCB fabricator will help avoid choosing a material set that may negatively impact Dk performance.

FR-4 Not Recommended: Note that FR-4 doesn’t have the same level of precise dielectric constant and thickness control as specially-formulated RF material. Don’t use it alone for RF applications.

Smooth Foil Prefered: Due to the skin effect, the smoother copper foil gets, the less resistive losses occur.

Why Choose XPCB™

RF PCB is a kind of special printed circuit board with high electromagnetic frequency. Generally speaking, high frequency can be defined as a frequency above 1GHz. As RF PCB carries prominent physical properties, accuracy, and technical parameters, it is often used in automobile anti-collision systems, satellite systems, radio systems, and other hi-tech fields.

RF PCB’s fabrication is much more complicated than standard PCB due to its high requirement for signal transmission and special laminate properties.

Extensive experience in popular RF PCB laminate materials, RF PCB materials are very different from FR-4 or Polyimide material, it requires more delicate treatment to prevent signal loss issue.

With years of experience in RF PCB fabrication, XPCB has cultivated a professional team who know how to turn your RF PCB concept into high quality prototypes at affordable price.
