High-Frequency PCB Manufacturing

High-quality and quick-turn high-frequency PCBs at competitive market prices

High-Frequency PCB Fabrication

A high-frequency PCB is suitable when integrating a particular signal with an electronic product. It boasts a frequency range of 500MHZ to 2GHZ, making it ideal for high-speed designs, radio frequency, microwave, and mobile applications. These higher transmission frequencies also offer faster signal flow rates essential in today’s increasingly complex electronic switches and components.
A high-frequency board requires specialized materials to establish high-frequency signals. Any slight change in the Er value of the materials will affect the PCB impedance. Most PCB manufacturers use Rogers dielectric material because of its lower dielectric loss, minimal signal loss, cost-effective circuit fabrication, and excellent appropriateness for quick-turn prototyping applications.
Besides selecting the suitable board material and determining the appropriate Er value, manufacturers also consider aspects like conductor width and spacing and substrate constant. These aspects should be precisely specified and executed with the highest process control level.

Why You Should Choose High-Frequency Circuits

If your application requires a high-frequency board, you need a PCB manufacturer with extensive knowledge and rich fabrication background. High-frequency boards are challenging to produce since they should maintain the thermal heat conduction of the application. This calls for an experienced manufacturer who understands this property and pays close attention to the PCB base material since even a slight modification can affect the PCB impedance.Some of the factors that we pay close attention to when fabricating high-frequency circuits include selecting the appropriate material, heat sinking capacity, signal loss tolerance, working temperature, and production cost.Most PCB manufacturers cannot handle the above aspects. By emphasizing features such as the thermal expansion coefficient, dielectric constant, dissipation factor, and thermal coefficient, we can manufacture high-frequency products that meet your custom requirements.

The Benefits of High-Frequency PCBs

High efficiency

High-frequency PCBs with small dielectric constant have minor losses, and the advanced induction heating technique can meet the target heating requirements. Apart from boosting a high efficiency, these boards are eco-friendly.

Fast

The conduction speed is inversely proportional to the square root of the dielectric constant. This implies that the lower the dielectric constant, the faster the transmission speed. High-frequency boards require unique base materials to achieve a small dielectric constant and maintain stable operation, boosting the signal integrity.

A high regulation degree

High-frequency PCBs, which is widely applied in different industries for the heating treatment of precision metallic materials, can achieve component heating with different depths and focus on heating as per the local features. Whether the heating techniques are for surface or deep level, you can quickly achieve concentration with the use of high-frequency boards.

High tolerance levels

The dielectric constant and medium display some environmental requirements. Standard boards are adversely affected by humid conditions. However, high-frequency PCBs consist of materials with low water absorption characteristics; hence, they can withstand humid weather. Besides, these boards are highly resistant to chemical corrosion, high temperatures, and peel pressure.
