[1] The overall Rth(j-a) value can vary depending on the board layout. To minimize the effective Rth(j-a) all power
and ground pins must be connected to the power and ground layers directly. An ample copper area directly
under the SAA7108AE; SAA7109AE with a number of through-hole plating, connected to the ground layer
(four-layer board: second layer), can also reduce the effective Rth(j-a). Please do not use any solder-stop
varnish under the chip. In addition the usage of soldering glue with a high thermal conductance after curing
is recommended.
