What implications will the transfer from desktop to mobile have on materials?

Expanding utilization of portable electronics, including communication equipment and computers, requires very good packaging efficiency; more functions and higher performance must be incorporated into an ever-smaller housing. New components and substrates must be developed to meet the challenge because higher component density is an inevitable trend. It is extremely important to find low cost components and substrates, with better performance and reliability than that required from their predecessors. Furthermore, interconnection technologies should fulfil the requirements for high-density assembly. A tremendous amount of development work is still needed so that materials coping with increased user needs can be introduced in time for volume production of next generation products
