ground pins must be connected to the power and ground layers directly. An ample copper area direct under the
SAA7108E; SAA7109E with a number of through-hole plating, which connect to the ground layer (four-layer board:
second layer), can also reduce the effective R
addition the usage of soldering glue with a high thermal conductance after curing is recommended.
