According to Puneet Gupta, Ph.D. and his colleagues at UCLA including Subramanian Iyer, Ph.D., the printed circuit board is a constraint on electronics size and speed. And the solution is to get rid of it. The professors have developed a method to replace PCBs with an all-silicon technology, called silicon-interconnect fabric, which allows bare chips to be connected directly to wiring on a separate piece of silicon. The wiring between chips on fabric is at the nanometer scale, much like the wiring within a chip. Dr. Gupta asserts many more chip-to-chip connections are thus possible, and those connections are able to transmit data faster while using less energy. He discusses the technology and its implications with PCB Chat host Mike Buetow.
