. The thermal resistance is referred to
the thermal path from the dissipating region on
the top surface of the silicon chip, to the points
along the four central pins of the package, at a
distanceof 1.5 mmaway from the stand-offs.
R
th j-amb1
If a dissipating surface, thick at least 35
μ
m, and
with a surface similar or bigger than the one
shown, is created making use of the printed cir-
cuit.
Such heatsinking surface is considered on the
bottomside of an horizontalPCB (worst case).
R
th j-amb2
If the power dissipating pins (the four central
ones), as well as the others, have a minimum
thermal connection with the external world (very
thin strips only)so that the dissipation takes place
throughstill air and through the PCB itself.
It is the same situationof point above,without any
heatsinking surface created on purpose on the
board.
