High-frequency printed circuit boards (PCBs) are used in a variety of electronic devices, including radio frequency (RF) and microwave devices, and are designed to support high-frequency signals. High-frequency PCBs have the following advantages:
- The PCB material should have a low dielectric loss and a stable dielectric constant. Although FR-4 is a popular material for high-frequency PCBs, other materials such as ceramic-based laminates or low-loss PTFE materials may be used in some cases.
- Trace width and spacing: To minimize signal loss and crosstalk, the width and spacing of the traces on the PCB should be carefully designed.
- Impedance control: The traces’ impedance should be adjusted to match the impedance of the signal source and load. This can be accomplished by using controlled trace width, thickness, and dielectric constant.
- Shielding: Shielding may be required for high-frequency PCBs to reduce the impact of electromagnetic interference (EMI) and to prevent signal loss. This can be accomplished by employing ground planes, copper shielding, and other techniques.
- Layout and routing: The layout and routing of the traces on the PCB should be carefully planned in order to minimize signal loss and crosstalk while maintaining the desired impedance.
- High-frequency PCBs can support a wide range of frequencies and can be designed to operate over a wide temperature range, resulting in improved performance of electronic devices.
- Improved signal integrity: High-frequency PCBs are designed to minimize signal loss and crosstalk, which can result in improved signal integrity and improved electronic device performance.

The assembled PCBs that were delivered worked flawlessly. The component placement is excellent. Mis wang, the WINOW engineer in charge of our project, and I hit it off right away. She asked pertinent questions to ensure that the project was properly completed. We had a very nice, short, and to-the-point conversation.
This board is required to charge my robotic platform's lipo batteries (rover). Excellent communication throughout the ordering process, manufacturing progress, and delivery tracking for a first-time order. Very reasonable price, especially for the first order with a credit for a discount.
The boards arrived yesterday, and assembly has begun. Excellent solder wetting, crisp line definition, and drill holes precisely in the center of via lands.
Please convey my appreciation to everyone who created such fantastic boards.
