Factors to consider when choosing Rogers materials

Although experienced Rogers PCB manufacturers will guide you to use the best Rogers substrates, it is important to know your application requirements. In addition, you can choose the right Rogers material based on a number of other factors:

Coefficient of thermal expansion:

According to the principle of material expansion when heated, PCB material will expand when exposed to a certain temperature. In general, they expand when the temperature exceeds the set glass transition temperature. The rate at which they expand above this temperature is called the coefficient of thermal expansion, expressed in parts per million (PPM).

Dielectric constant:

Stable dielectric constant is very important, especially in high frequency applications. The dielectric constant is basically the amount of charge stored in the PCB material, and its higher value will lead to higher capacitance and increase the voltage through the PCB. The dielectric constant of Rogers 4350b is 3.66, so it is very suitable for microwave point-to-point link.

Moisture absorption:

Ideally, the material should not absorb any moisture even when immersed in water; however, this is very unrealistic. However, it is important to minimize moisture absorption. The moisture absorption of most materials used for PCB is between 0.01% and 0.2%. Materials with low absorptivity will have better thermal and electrical properties.

Decomposition temperature:

The maximum and minimum temperature that PCB can bear should be determined according to the application, and the correct material should be used for corresponding design. If there is any possibility that the temperature will exceed its upper limit, there should be a reverse mechanism. Otherwise, PCB will decompose and lose a certain proportion of quality. For most applications, the ideal upper limit is 350 degrees Celsius. The decomposition temperature should be set outside this range.
