[1] The overall R_th(j-a) value can vary depending on the board layout. To minimize the effective R_th(j-a) all power and ground pins must be
connected to the power and ground layers directly. An ample copper area directly under the SAA7104E; SAA7105E with a number of
through-hole plating, connected to the ground layer (four-layer board: second layer), can also reduce the effective R_th(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.
