MOUNTING INSTRUCTION
The Rth-j-amb of the L4962 can be reduced by
soldering the GND pins to a suitable copper area of
the printed circuit board (Fig. 32).
The diagram of figure 33 shows the R
function of the side "l" of two equal square copper
areas having the thickness of 35 (1.4 mils). During

as a
soldering the pins temperature must not exceed
260 C and the soldering time must not be longer
than 12 seconds.
The external heatsink or printed circuit copper are
must be connected to electrical ground.
