Jesd51-7 board
WebThe measurement of RθJA is performed using the following steps (summarized from EIA/JESD51-1, -2, -5,-6, -7, and -9): Step 1. A device, usually an integrated circuit (IC) package containing a thermal test chip that can both dissipate power and measure the maximum chip temperature, is mounted on a test board. Step 2.
