6. Developments
The aim of these developments is to improve reliability or electrical or thermal performance. It's the applications that drive industrial developments, even if it's basically the processes and materials that need to be adapted.
6.1 Materials
There are many possible ways of classifying materials. The basic characteristics have been listed with the most common materials.
These properties correspond to grades commonly used and deployed by NEMA in particular, and synthesized in the IPC-4101 standard (specification of base materials for rigid and multilayer printed circuits). The IPC-4101 is regularly updated with new references, including the latest developments in "lead-free".
These characteristics can be detailed...

Standards and norms
The French NF 93713 and European UTE 93703 standards, although still in use and valid for standard printed circuit boards, are no longer updated for advanced processes, and have been superseded by the American IPC standards ( http://www.ipc.org ): The institute for interconnecting and packaging Electronic circuits.
