Default Rigid PCB Specifications

When we are given no other information, we will assume the following industry standard specifications. Of course, we'd rather not make assumptions, so even if these standard specifications match how you'd like your PCB constructed, it's always a good idea to state this either in a fab layer in the Gerber or in a readme.TXT, PDF, DOC(X), XLS(X), or DWG file. This way there is no question as to how your board should be constructed.

Even if these specifications are what you expect, it's always a good idea to list your requirements in a fabrication drawing so there's no mistake or confusion. You don't have to make a fancy fabrication drawing. A simple readme.txt file works just as well. We can accept nearly any standard format for your fabrication notes. Other fab print file types we can use are:

.TXT .JPG
.PDF .PNG
.DXF .XLS
.DWG .XLSX
.DOC .PPT
.DOCX  

Viewing Files

A few tips regarding how your files will be interpreted unless we are given other information.

  1. Industry standard is to view your files as seen from the top side of the board. This is to ensure all features such as holes are aligned correctly when building your design. When viewing this way, any text printed on the bottom side of the board will appear backwards since we are viewing it from the top side looking though the board… just like Superman with X-ray vision!
  2. Because lines of varying widths can be used to draw outlines, the CENTER of the line used to draw any board outline, cutout or slot will be used as the true edge of that feature.
  3. It's always a good idea to add some overall dimensions to your Gerber or fab print information. This is a good reality check to ensure your file imported into our software correctly and we are seeing it at the intended scale.
