5. Conclusion and outlook

Electronic boards are of recognized strategic importance in guaranteeing the performance of computer systems. Their foreseeable development prospects are closely linked to those of integrated circuits and processors:

• greater integration;

• increasing chip size;

• increasing the speed of digital systems, and therefore power dissipation.

New technologies are moving from the research and development stage to industrial use and point to new directions (figure 31 ):

• use of new organic materials with improved performance: lower dielectric constant, lower losses, better temperature resistance;...
