Packaging pervades a system at multiple levels or hierarchies. Explain these levels and the design constraints in the context of four very different systems using clearly labeled diagrams: (a) a high-end server in a data center (b) a portable appliance such as a smart phone (c) A LED bulb (d) A MEMS resonator Packaging pervades a system at multiple levels or hierarchies.
