Thanks for your relpy! Could you explain the layer tabel that I transferred from gerber file to CAM file in Altium Designer specificily? For example,what is the difference between "smd0042" ,"sm0248" and "smd0123" ,and which layer is the top layer ? "art001" or others? The screenshot of layer table has been placed in the attachment，thanks!

Hi,

Layers are as given below:

-art1, art2, art3 and art4 are the top, second, third and bottom copper layers, respectively

-dd124 is drill drawing

-sm0121 is top soldermask

-sm0428 is bottom soldermask

-sm004022 is bottom pastemask

-smd0123 is top pastemask

-sst001026 is top silkscreen

- drl01 is drill file

Kudret

I appreciate your help very much. In addition, I would like to ask how you determine the layer type in Alutim designer，is there a universal method or the official instructions from ADI (maybe I did not find it)

Hi,

I am not familiar with Altium and not able to provide a method for you.

I guess it should be a common question and an answer can be found easily on the web.

Kudret

thanks!
