hi everyone
i have my first PCB design and before i send it
to PCB manufacture i need to some expert guys check
my PCB.

I work with PADS and my PCB output is in Gerber format.

here it is :

Download - Gerbers.rar - Persiangig

this is a very simple PCB in 2 Layer.

please help me. i need to someone check
this Gerbers and inform me if there is any error on it.

Thanks.

I'm missing a specification of the involved gerber formats. The scaling seems strange, I got ten times the physical size when reading the data to GCPrevue. Also the gerber files have arbitrary offsets, I would prefer the lower left corner aligned to zero. Drill data have been generated without an embedded tool table and have an offset different from gerber data.
I guess, Pads should be able to do better.

Apart from this points, the data look reasonable. If the PCB manufacturer is able to guess the right design size, align the drill data and add a tool table, it can work. But you can increase the chance to get it right by adding the said information and aligning gerber and drill data to the same offset.

thanks . very useful information.
Why PCB manufacturer must guess PCB size ?
PCB size must be in Gerber files . Isn't it ?

How i can match drill size with PCB layers ?
In PADS there is no option or i can't see it.
please help me if there is anyone that works with PADS.

Size must mention when ordering PCB or i must set it on Gerber files ?

No because different gerber formats are in use. You should specify both, the PCB size and the gerber format according to your setup. Many PCB systems are creating project reports containing this information, I don't know with Pads. But you can always write the information to a text file.

The problem with your drill data is, that it doesn't contain tool information, it can be only found in a report file. Most PCB systems allow to embed the tool information in the drill file.

When creating Gerbers always use 1 more decimal point than your smallest design grid at least, thus if you layout in thou use at least 3.4 format at least. (inegers/decimals)
