mpc860 powerquicc? family hardware specifications, rev. 8 12 freescale semiconductor thermal calculation and measurement 7 thermal calculation and measurement for the following discussions, p d = (v dd i dd ) + pi/o, where pi/o is the power dissipation of the i/o drivers. 7.1 estimation with junction-to-ambient thermal resistance an estimation of the chip junction temperature, t j , in oc can be obtained from the equation: t j = t a + (r ja p d ) where: t a = ambient temperature (oc) r ja = package junction-to-ambient thermal resistance (oc/w) p d = power dissipation in package the junction-to-ambient thermal resistance is an i ndustry standard value which provides a quick and easy estimation of thermal performance. however, the answer is only an estimate; test cases have demonstrated that errors of a factor of two (in the quantity t j ? t a ) are possible. 7.2 estimation with junction-to-case thermal resistance historically, the thermal resistance has frequently been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: r ja = r jc + r ca where: r ja = junction-to-ambient thermal resistance (oc/w) r jc = junction-to-case thermal resistance (oc/w) r ca = case-to-ambient thermal resistance (oc/w) r jc is device related and cannot be influenced by the user. the user adjusts the thermal environment to affect the case-to-ambient thermal resistance, r ca . for instance, the user can change the airflow around the device, add a heat sink, change the mounting arra ngement on the printed-circ uit board, or change the thermal dissipation on the printed-circuit board surrounding the device. this thermal model is most useful for ceramic packages with heat sinks where some 90% of the heat flows through the case and the heat sink to the ambient environment. for most packages, a better model is required. 7.3 estimation with junction-to-board thermal resistance a simple package thermal model which has dem onstrated reasonable accuracy (about 20%) is a two-resistor model consisting of a junction-to-boa rd and a junction-to-case thermal resistance. the junction-to-case thermal resistance covers the situation where a heat sink is used or where a substantial amount of heat is dissipated from the top of the package. the junction-to-board thermal resistance describes the thermal performance when most of the he at is conducted to the printed-circuit board. it has been observed that the thermal performance of most plastic packages, especially pbga packages, is strongly dependent on the board temperature; see figure 2 .
mpc860 powerquicc? family hardware specifications, rev. 8 freescale semiconductor 13 thermal calculation and measurement figure 2. effect of board temperature rise on thermal behavior if the board temperature is known, an estimate of the junction temperature in the environment can be made using the following equation: t j = t b + (r jb p d ) where: r jb = junction-to-board thermal resistance (oc/w) t b = board temperature (oc) p d = power dissipation in package if the board temperature is known and the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made. for this method to work, the board and board mounting must be similar to the test board used to determine the junction-to-board thermal resistance, namely a 2s2p (board with a power and a ground plan e) and by attaching the thermal balls to the ground plane. 7.4 estimation using simulation when the board temperature is not known, a thermal s imulation of the application is needed. the simple two-resistor model can be used with the thermal simulation of the application [2], or a more accurate and complex model of the package can be used in the thermal simulation. 7.5 experimental determination to determine the junction temperature of the device in the application after prototypes are available, the thermal characterization parameter ( jt ) can be used to determine the junction temperature with a measurement of the temperature at the top cente r of the package case using the following equation: t j = t t + ( jt p d ) board temperature rise above ambient divided by package power junction temperature rise above ambient divided by package power
