everyone. I have a problem with one of my designed boards. I submitted my order to PCBWay for checking my files before ordering and I was informed that there is no bottom Soldermask layer. This confused me since I have not encountered any layer named as such in the EAGLE layers list. Maybe this is a layer that exists in that list? I have browsed online and found that the areas on tStop and bStop are where the solder mask is not applied. Since I do not have any components or pads in the bottom only a few traces as I used vias, how do I enable or incorporate this layer into my design?
Some of the suggestions that PCBWay was kind enough to give are:
- Cover with the solder mask ink all
- Do solder mask opening all
- Or you can add the layer and resubmit the file.
I am not sure how to do this task related to the solder mask. If you have anything to share a link to a tutorial or video (I tried finding to no avail), please do share. I thank you for taking your time to read, looking forward to learning from everyone.
