Production precautions

Material Selection: 

Rogers materials are known for their excellent high frequency performance and are suitable for high frequency circuit boards. Be sure to select a specific model such as RO4350B that is suitable for the application frequency and performance requirements.

Thickness Selection: 

The thickness of the PCB will affect the impedance bandwidth of the microstrip antenna. Thinner PCBs can provide wider bandwidth, but may require more delicate processing techniques.

Surface Treatment: 

The immersion gold process provides good corrosion resistance and weldability, but it is necessary to ensure the uniformity and thickness of the immersion gold layer to avoid the risk of gold wire short circuit.

Process Control: 

Optimize the immersion gold process and accurately control process parameters, such as temperature, time, solution concentration, etc., to ensure the uniformity and quality of the coating.

Quality Inspection: 

Introduce an advanced quality inspection system to strictly inspect PCB boards in each production link, and promptly discover and deal with potential quality problems.

Safety and Environmental Protection: 

When handling potions containing highly toxic substances such as gold salts and cyanides, appropriate safety measures must be taken, such as wearing acid and alkali-resistant gloves, protective goggles, etc., and ensuring that waste gas and waste liquid are specially treated.

Employee Training: 

Regularly train employees on skills and quality control to improve their mastery of processes and quality awareness.

Interconnect Design: 

In high-frequency applications, the design of metallized vias requires special attention to avoid introducing excessive discontinuities and transmission losses.

Low Side-lobe Design: 

For array antennas, it is necessary to achieve low side-lobe levels through feed network design to reduce environmental interference and improve radar signal-to-noise ratio.

Impedance Control: 

The impedance of the transmission line needs to be precisely controlled during design to ensure signal integrity and minimize reflections.

Thermal Management: 

High frequency circuits may generate more heat, and the heat dissipation design of the PCB needs to be considered.

Design Rules: 

Follow Rogers Materials design rules and guidelines to ensure circuit performance.

Mixed Voltage Technology: 

If multi-layer mixed voltage technology is used, the influence between different material layers needs to be considered, such as dielectric constant, thermal expansion coefficient, etc.

Testing and Verification: 

Conduct sufficient testing and verification before and after production to ensure that the PCB meets high-frequency performance requirements.

By paying attention to these matters, you can ensure the production quality of Rogers 2-layer F4B immersion gold PCB to meet the stringent requirements of high-frequency applications.
