thermal

1. of, relating to, caused by, or generating heat or increased temperature
2. (of garments or fabrics) specially designed so as to have exceptional heat-retaining properties
3. Meteorol a column of rising air caused by local unequal heating of the land surface, and used by gliders and birds to gain height

thermal

[′thər·məl]
(meteorology)
A relatively small-scale, rising current of air produced when the atmosphere is heated enough locally by the earth's surface to produce absolute instability in its lower layers.
(thermodynamics)
Of or concerning heat.

thermal

A column of rising air heated by the sun or other phenomena. Sailplane and glider pilots use it for soaring. The pilots recognize the presence of a thermal with the help of a variometer—an instrument having two tubes with red and green indicators. A red means a downward air current, and a green means an upward air current, or a thermal. See variometer.

where K and L are the thermal conductivity coefficient and thickness of the die-attach material and A is the heat transfer area.
By (1) and Table 2, the thicknesses of die-attach layer change from 38.8 [micro]m to 8.4 [micro]m and the thermal resistance of material reduced about 0.35[degrees]C/W, but thermal resistance of die-attach layer reduced 1.96[degrees]C/W.
