Layer Stackup

When preparing your order for production we have to assign each file to a physical layer of your board. In most cases we can determine which layer is being depicted from the file name, file extension, or header information. However if we are unable to do so we may require a guide stating which layer is depicted in which file.

We refer to guides like these as layer stackups.

A layer stackup can be as simple as a text document listing each file name and the physical layer it belongs to on each line, please see the example below. It can also be helpful to include any special information about layers, such as their intended polarity.
