Electromagnetic radiation study of Intel Dual Die CPU with heatsink

This paper presents an EMC modelling approach for the latest dual die CPU with a heatsink from an antenna point of view. The model acts as a very efficient antenna while its structure is constructed almost according to a real dual die CPU structure. Different sizes of heatsink cooperate in the investigation of electromagnetic characterization. Simulation and measurement are accomplished in far-filed range. The results show that the dual die model without heatsink is resonating at two frequencies which are 2.04GHz and 4.9GHz. When a heatsink is mounted however the resonant frequencies are changed to 1.80GHz and 5.20GHz respectively.

Due to the variety of internal structures applied in different processors, EMC modelling should also be upgraded correspondingly. This paper presents an upgraded EMC simulation model of dual die structure which is originated from the IEEE electromagnetic challenging problem 2000-4 for conventional CPU with heatsink. The simulation results are verified by measurement with a fabricated model. Furthermore, a consequent benchmark will be provided.
