Printed circuit board materials

Leiterplatten-Material Hersteller

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 materials can be found in following PDFs:

On request, you can order circuit boards with EN45545-2: 2013 certified Isola material (fire protection requirements for rail vehicles): EN45545-2: 2013 Information.

Please note: The selected materials may be replaced by technically equivalent or similar products, according to available stocks on hand.

Unless otherwise noted, the CTI (Comparative Tracking Index) which indicates the tracking resistance, is PLC3 (175V - 250V) for rigid PCBs. On request, we are also able to produce PCBs with PLC 2 (> 250V), PLC 1 (> 400V) or PLC 0 (> 600V). See Overview of CTI / PLC.
