op amp in pcb

[blowouter]

i design hand clap switch on PCB it contain mic , op amp, relay
i try to make it as small as possible in dimensions
is there any precautions i must care and take it into account in layout
for noise, high voltage etc.
i plan to make the relay side by side on board with mic and op amp
the PCB will be 8*8 cm
thanks

Hi,
If you post your circuit we can check it out for you and make some recommendations.

the ics are 741,4001,4027 the relay is the yellow block

Post the schematic.

Is the circuit diagram for this PCB the one you have posted on your earlier CMOS clap Thread.?????

Post it here.

this is the second circuit in the previous thread


the schematic



is there any thing to get into consider in PCB

Why don't you try it on a breadboard first? Going straight to pcb with something you got from the internet and have no clue about how it works will very likely end up not working at all. And changing things on a pcb is quite difficult and messy.

try to simulate it via proteus, make sure that the circuit is ok.

OK i will try again in breadboard and give you the result
thanks
