The thermal characterization parameter is measured per JESD51-2 specification using a 40-gauge type T
thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so
that the thermocouple junction rests on the package. A small amount of epoxy is placed over the
thermocouple junction and over about 1mm of wire extending from the junction. The thermocouple wire
is placed flat against the package case to avoid measurement errors caused by cooling effects of the
thermocouple wire.
When heat sink is used, the junction temperature is determined from a thermocouple inserted at the
interface between the case of the package and the interface material. A clearance slot or hole is normally
required in the heat sink. Minimizing the size of the clearance is important to minimize the change in
thermal performance caused by removing part of the thermal interface to the heat sink. Because of the
experimental difficulties with this technique, many engineers measure the heat sink temperature and then
back-calculate the case temperature using a separate measurement of the thermal resistance of the
interface. From this case temperature, the junction temperature is determined from the junction-to-case
thermal resistance.
12.2 Electrical Design Considerations
Use the following list of considerations to assure correct operation of the 56F8037/56F8027:
Freescale Semiconductor
Provide a low-impedance path from the board power supply to each V
from the board ground to each V
The minimum bypass requirement is to place 0.01–0.1µF capacitors positioned as close as possible to the
package supply pins. The recommended bypass configuration is to place one bypass capacitor on each of
the V
tolerances.
Ensure that capacitor leads and associated printed circuit traces that connect to the chip V
pins are as short as possible
Bypass the V
PCB trace lengths should be minimal for high-frequency signals
Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance.
This is especially critical in systems with higher capacitive loads that could create higher transient currents
