How to Choose the Base Material of High Frequency PCB Board

High frequency PCB plays an important role in wireless communication, radar, satellite communication and other fields. Choosing the right high frequency PCB base material is crucial to ensure the performance and reliability of the PCB. However, since there are various types of PCB boards on the market, how to choose the right board becomes a key issue. So how to choose high frequency PCB board?

 

Factors to consider when choosing high frequency PCB base material:

1) Dielectric Constant: The dielectric constant is an index to measure the electrical insulation ability of materials, which is especially important for high -frequency PCB. A lower dielectric constant helps reduce signal loss and signal distortion during signal transmission.

 

 

2) Dielectric Loss Factor: Dielectric loss factor is a parameter to measure the degree of dielectric loss. Choose materials with a low dielectric loss factor to ensure the accuracy and stability of signal transmission.

 

 

3) Thermal Stability: High frequency PCB usually operate at higher operating temperatures, so thermal stability is an important consideration. Choose materials with good thermal stability can ensure that PCB will not lose its performance due to temperature changes.

 

 

4) High Frequency Performance: For high frequency PCB, it is also necessary to consider the high frequency performance of the material, including the stability of the dielectric constant and the loss of signal transmission. This helps maintain the integrity of the signal and the accuracy of high-speed data transmission.

 

 

5) Tg Value: Tg refers to the temperature at which the PCB material transitions from a solid state to a molten state. In high temperature environment, higher Tg value can ensure the stability and reliability of PCB.

 

 

6) Moisture Absorption: The hygroscopicity of the PCB board will affect the performance stability of the circuit. Choosing a board with low hygroscopicity can reduce the effect of moisture on the circuit.

 

 

In addition, high  frequency PCB has the advantages of high efficiency, fast speed, moisture resistance and high temperature resistance, which make it widely used in many high-precision instruments. SHENZHEN HOYOGO ELECTRONIC TECHNOLOGY CO., LTD. is an international, professional and reliable high frequency PCB manufacturer. Since 2006, we have our own production bases in China, mainly focusing on exporting PCB&PCBA to European and North American markets.

What are the Advantages and Disadvantages of the OSP Technology

图片
     With the continuous development of the electronics industry, there are more and more PCB surface treatment technologies, and each technology has its own merits. OSP is a commonly used surface treatment technology process, what are its advantages and disadvantages?       Compared with other surface treatment technologies, OSP is somewhat different.  It uses a chemical method to produce an organic film on the clean bare copper surface, which acts as a barrier between the copper and the air.   OSP is organic, not  metallic,   and its cost is lower than most surface treatment technologies.     Advantages: With this organic film, it can resist the attack of moisture in the air without being oxidized before welding,  can withstand the test of high temperature, maintain good activity, and has a good tinning ability.  This layer of organic film will not cause damage to the sheet material. It can be easily removed by the solder resist during soldering. It can solder the copper wire and the

What PCBA Problems Can AOI Inspect

图片
        With the development of science and technology, the volume of PCBA is getting smaller and more precise, and some defects in processing cannot be distinguished with the naked eye, so AOI has appeared.  So what PCBA problems can AOI inspect?   The working principle of AOI is to first collect and input parameters such as images, component positions, solder joints and other parameters of the good-quality board.   During the inspection, the instrument automatically scans the circuit board and automatically captures the image, and then compares the collected data with the pre-entered parameters to determine whether the characteristics of solder joints, components and other aspects are consistent. If the data is inconsistent, the d efect  will be flagged through the display for maintenance personnel to repair.     AOI is mainly used to inspect solder paste printing, component placement and soldering. For example: too much or too little solder paste,   solder paste printing offset;  co
