With the progress of modern science, the development of electronic communication has also become increasingly rapid. In order to meet the needs, many simple circuit boards are gradually developing into high-frequency and high-precision circuit boards. How to define ordinary and high-frequency boards?
1. The thermal expansion coefficient of the substrate of the high-frequency board and the copper foil must be consistent, otherwise it will cause copper foil separation during the process of cold and hot changes.
Qunhui circuit board 2. The water absorption of the high-frequency board substrate should be low. If the water absorption is high, it will get damp, which will lead to dielectric constant and loss
3. Secondly, his heat resistance, chemical resistance, impact strength, and peel strength must be good
4. The dielectric loss of the substrate material for high-frequency and high-precision circuit boards must be small, which mainly affects the quality of signal transmission. The smaller the dielectric loss, the smaller the signal loss.
5. High frequency circuit board substrate materials must also have good heat resistance, chemical resistance, impact strength, peel strength, etc. Generally speaking, high frequency can be defined as a frequency above 1GHz. The commonly used high-frequency circuit board substrate is fluorine based dielectric substrate, such as polytetrafluoroethylene (PTFE), commonly known as PTFE, which is usually used above 5GHz. Additionally, FR-4 or PPO substrates can be used for products between 1GHz and 10GHz.
