Commonly used PCB material classification

As a new technology, PCB has the characteristics of concentrating the functions required by electronic equipment in a limited space. In recent years, its development has been even more vigorous. And the more such a small and precise device, the more stringent the selection of its materials. So what materials do PCB circuit boards have? Let’s focus on it today.

The commonly used PCB board materials are classified as follows:

Bakelite: Use the recommended maximum frequency of 100MHZ; although its price is low, its strength is too weak to meet our functional requirements for PCB circuit boards, so it has basically withdrawn from the production stage.
Paper resin board: The recommended maximum frequency is 300MHZ; the price is medium and the strength is weak.
Glass resin board: The recommended highest frequency is 1GHZ; the price is beautiful and very hard, suitable for most PCB circuit boards, and therefore it is one of the "most used" varieties.
Tiefulong: A special PCB material, the highest frequency is 5GHZ; but it is not only expensive, but also fragile, and it is rarely seen in normal use.
Ceramic materials: Laser or high-speed water processing machine tools are required for both processing and cutting. It is generally only used in thick film circuits and the aerospace industry; it is not difficult to understand it. You can usually find one or two in old bad TV sets.
These are all PCB materials that we can usually see. Of course, they can be divided into more details according to different standards. For the purpose of understanding, it is probably enough to know so much! I hope I can help you who love PCB a little bit!
