2-layer PCB design, through hole technology and ground plane

manpreet Best Answer 2 years ago

I am designing the layout of a PCB for audio applications (no digital electronics, only analog).

All components are through hole, the PCB is pretty large (about 16cm x 10cm) and has 2 layers. Plated through hole are supported by the technology I am using. The circuit has a dual supply.

Which (and why) of the following is the best solution for routing signals, power supply tracks and ground?

• TOP layer: ground plane; BOTTOM layer: signals and supply lines;
• TOP layer: signals and power supply lines: BOTTOM layer: ground plane;
• TOP layer: ground plane and supply lines; BOTTOM layer: signals;
• TOP layer: signals; BOTTOM layer: ground plane and supply lines;
