Factors affecting the performance of FR4 sheet:

Temperature: 

Temperature is one of the key factors affecting the performance of FR4 sheet. As the temperature rises, certain properties of FR4 sheet may change, such as thermal conductivity. Therefore, when using FR4 sheet, you need to consider the temperature of its working environment to ensure its stable performance.

Humidity and Relative Humidity: 

Humidity and relative humidity can also affect the performance of FR4 sheets. Excessive humidity may lead to a reduction in the insulating properties of the sheet, so care needs to be taken when using FR4 sheet in humid environments.

Vacuum: In some specific applications, the vacuum level may also have an effect on the performance of FR4 sheet. For example, certain physical and chemical properties of FR4 sheet may change under high vacuum.

The Quality of The Material Iitself: 

High-quality FR4 sheets typically offer more consistent performance and a longer service life. Therefore, when choosing FR4 sheet, you should choose high-quality products produced by regular manufacturers.

To summarize, FR4 sheet has a variety of excellent properties, but its performance may be affected by a variety of factors such as temperature, humidity, vacuum and so on. Therefore, when using FR4 sheet, you need to fully understand its performance characteristics and application environment to ensure its stable and reliable performance.
