MC100ES6220
APPLICATIONS INFORMATION
Using the Thermally Enhanced Package of the
MC100ES6220
The MC100ES6220 uses a thermally enhanced exposed
pad (EP) 52 lead LQFP package. The package is molded so
that the lead frame is exposed at the surface of the package
bottom side. The exposed metal pad will provide the low
thermal impedance that supports the power consumption of
the MC100ES6220 high-speed bipolar integrated circuit and
eases the power management task for the system design. A
thermal land pattern on the printed circuit board and thermal
vias are recommended in order to take advantage of the
enhanced thermal capabilities of the MC100ES6220. Direct
soldering of the exposed pad to the thermal land will provide
an efficient thermal path. In multilayer board designs, thermal
vias thermally connect the exposed pad to internal copper
planes. Number of vias, spacing, via diameters and land
pattern design depend on the application and the amount of
heat to be removed from the package. A nine thermal via
array, arranged in a 3 x 3 array and using a 1.2 mm pitch in
the center of the thermal land is a requirement for
MC100ES6220 applications on multi-layer boards. The
recommended thermal land design comprises a 3 x 3 thermal
via array as shown in Figure 6, providing an efficient heat
removal path.
Figure 6. Recommended thermal land pattern
The via diameter is should be approx. 0.3 mm with 1 oz.
copper via barrel plating. Solder wicking inside the via
resulting in voids during the solder process must be avoided.
If the copper plating does not plug the vias, stencil print solder
paste onto the printed circuit pad. This will supply enough
solder paste to fill those vias and not starve the solder joints.
The attachment process for exposed pad package is
equivalent to standard surface mount packages. Figure 7
shows a recommend solder mask opening with respect to the
recommended 3 x 3 thermal via array. Because a large solder
mask opening may result in a poor release, the opening
should be subdivided as shown in Figure 7. For the nominal
package standoff 0.1 mm, a stencil thickness of 5 to 8 mils
should be considered.
Figure 7. Recommended Solder Mask Openings
For thermal system analysis and junction temperature
calculation the thermal resistance parameters of the package
is provided:
It is recommended that users employ thermal modeling
analysis to assist in applying the general recommendations
to their particular application. The exposed pad of the
MC100ES6220 package does not have an electrical low
impedance path to the substrate of the integrated circuit and
its terminals. The thermal land should be connected to GND
through connection of internal board layers.
