how to apply copper pour to analog board using 16.3?

[danismith]

hai friends,
can any one tell me whether it is wright or wrong,

am already started to route an analog board,while routing should i increase the thickness of a track or to apply copper pour and then cut it according to the width which i wish?

come on geni,,,
help me

Track thickness increase ur board cost. U should apply copper as per ur requirement or after etching u should apply solder metal & cu wire on required track to increase thickness of track

You need to be precise about whether you mean 'width' or 'thickness'. What width tracks do you require? Are you trying to make a ground plane?

It depends on what you are routing, sometimes a thick track will suffice, for example if you are supplying a few devices with power. Sometimes a copper pour is more appropriate, such as a switching node or local switching ground node of a switch mode power supply design.

hi,
am started with the ac line,from the right bottom terminal block -> bridge rectifier->dc->primary ->secondary.so according to this i need to change the track thickness.

i saw some of the board with the width of 5mm.
and in some with the thickness of extra solder mask.

which one is wright?
and tell me the exact measurement.

Use the track width calculator.
A copper pour will dissipate heat better than a single track allowing more current to be carried. It is never a good idea to rely on solder over traces to increase current, the capacity of solder is not as good as copper, and these days higher weight base laminate are readily available. Also the quality control is much easier as the copper will be the weight (thickness) specified, whereas a solder coating is variable. You can get copper buzz bars that will fit on a PCB and are soldered down at numerous points, usually through hole:
