In practice PCBs are not “free space” and thus the transmission distance to get a signal out of a CPU chip and get data back from a memory chip is around four inches of PCB track, if the memory chip responds instantly (which it can not). Which is why motherboard bus speeds sound ...
With the application of quantum mechanics, designers recognize that product failure occurs from microscale or nanoscale voids observed in engineering plastics or metallic alloys. If limited parts and testing times are used [19–24], this approach may not reproduce the structural imperfec- tions of ...
