#103333 - Solid ground plane is needed!
Responding to: Suresh R's previous message
Suresh said:
In two layer micro based PCB design can i have connected the GND net to Bottom layer copper pour. But i have doubt whether i could connect the Vcc (+5VDC) to Top layer copper pour.


If you want to design something reliable, then you need a piece of ground under each single signal, so you will need a PCB containing a solid ground plane. Remember, that noise on ground is much more critical than noise on Vcc. So, fill every free area on your board with ground, connect it to your ground plane by as many vias as possible and use proper supply decoupling with each chip.
