What is the size of ground and VCC wires?

[nan_ishan]

Ground and VCC wires

It depends on how much the supply you are using in ckt.
Mostly in purely electronic ckts it is arround 2.5 to 3 mm maximum.

i think the track size mentioned will be used in power supply boards for a normal micro controller board with a 5V VCC we can use .5mm track and a good ground copper pour

Re: Ground and VCC wires

some years back..I have this estimated current loading capacity for trace

0.254mm = 0.3A, 0.381mm=0.4A, 0.508mm = 0.7A, 0.635mm=1.0A, 1.27mm=2.0A, 2.54mm=4.0A, 3.81mm=6.0A

Hi,

It needs lots of inputs and other factors decides its trace thickness,for eg..

1) its application..

2) density & critical signals.

3) emi issues.

4) Its current carrying,for eg smps pcb..

Please be more specific what your looking for..

Regards,

Ramesh

Ground and VCC wires

You also have the ambient temperature to take into account.

Hi,

Trace width always depends upon the current value and raise in temperature.

Check out the link below and u will find the calculator which will meet your requirement.
