High Frequency PCB

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 (RF), 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.

MKTPCB is a full-service printed circuit board manufacturer that offers reliable, quality high-frequency PCB manufacturing services at competitive market prices. We fabricate high-frequency circuits with frequencies ranging from 500MHZ to 2GHZ.

Why You Should Choose MKTPCB’s 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.

Quality Assessment Tests for Our High-Frequency PCB Products

At MKTPCB, we are obsessed with quality, and we always aim for a flawless design and functionality of our high-frequency PCB products. We have laid out a 5-step quality inspection procedure to ensure our products are 100% functional:

First Article Inspection (FAI)

MKTPCB acknowledges FAI as the initial step of quality inspection before the mass production of circuit boards. We put up this step to avoid producing large quantities of defective products due to processing and operational issues.

We inspect every resistor, capacitance, and inductance using an LCR meter. Besides, we use QC with BOM and Assembly drawing to verify chips.

Automatic Optical Inspection (AOI)

The AOI process verifies the placement of electronic components and solder joints after SMT. The primary objective is to get the highest quality control and detect and remove defects in the earlier stages of the assembling process.

X-Ray Inspection

In this step, we use short wavelengths of 0.0006-80nm to penetrate various PCB materials. Designs with BGA and QFN packages have solder joints that are not easily visible by human eyes. We employ X-ray machines to inspect such packages in the final printed circuit board assembly.

Final Quality Assurance (FQA)

After carrying out FAI, AOI, and X-Ray inspections, our quality engineers conduct the last visual quality inspection process for all products. This process ensures that products have gone through all the assembling processes and are of good quality.

Function Test

Finally, we also conduct functional tests on all automated test equipment to simulate different loads, typically average, peak, and abnormal loads. This is a complicated process that involves various tool-based and programming tests. Additionally, this step requires customer technical support.

What is a High-Frequency PCB

A high-frequency PCB is a special board with high electromagnetic frequency, commonly applied in applications requiring frequencies of more than 300MHZ. The base materials of high-frequency boards must possess excellent electrical properties and chemical stability. With the rise of power signal frequency, the substrate loss requirement is negligible, highlighting the significance of high-frequency materials.

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.

Application of High-Frequency Boards

  • Medical applications like X-ray equipment, Heart rate monitors, MRI scanners, blood glucose monitors, etc.
  • Mobile communication gadgets, receivers, and intelligent lighting system.
  • Radar systems, marine and aviation industries.
  • Power amplifier, low noise amplifier, and others.
  • Power divider, coupler, duplexer, filter, and other passive components.
  • In automobile anti-collision systems, satellite systems, and radio systems, the high frequency of electronic equipment is the development trend.
