Various requirements for printed circuit boards make the use of different circuit board substrates necessary.
Whereas for many standard applications the classical FR4 material is sufficient, possibly in high Tg version (for improved thermo-mechanical properties), for other areas (such as high frequencies) alternate materials are absolutely required.
The following information is intended as a abstract summary of all available material types and their fundamental properties, to make it easier for you to make a selection according to the required field of application.
The standard values of the processed FR4 materials can be found in following PDF:
