Electronic assembly with integral thermal transient suppression

摘要

An electronic assembly (100) with integral thermal transient suppression includes an integrated circuit (IC) chip (106) disposed within a cavity (103) of an IC device package (102). A transient thermal suppression material (TTSM) (110) is disposed in the cavity (103) in thermal contact with the IC chip (106). A heat sink (112) may also be provided in thermal contact with the chip (106). When present, the heat sink (112) serves as a cover of the packaged IC chip (106) and may include fins (112A,112B) extending from an upper surface (in contact with air) and a lower surface (in thermal contact with the TTSM (110)).The TTSM (110) may be thought of as a phase change material that absorbs energy dissipated by the IC chip (106) in a phase change event.
