Feature: Thermal management


Figure 1: 5G deployment consists of two new bands and existing low frequency bands


used today are below 4W/mK thermal conductivity, the demands of future 5G devices could push this requirement into the 5-10W/mK range.


Latest report on thermal management IDTechEx’s latest report on “T ermal Management for 5G” addresses the trends in 5G deployment and how


this impacts antenna design, choice of semiconductor technology, die attach materials and thermal interface materials. Technological aspects and market forecasts are included for the next ten years. Additionally, the report considers many smartphones and how the incorporation of 5G is impacting thermal materials – interface and heat spreaders.
