I have a 2-layer board design. with layer 1 being the signal plane and layer 2 being the ground plane. when I try to generate the Gerber files in Expedition PCB, Everything seems to be ok except for the ground plane. I put my design through a free dfm check and the gnd plane does not show up any where. The engineer who did the check also said there was no ground plane in the files that I sent them. They suspected that while generating the files, Expedition PCB might not be extracting the gnd plane. Does "plane data state" in plane assignments have anything to do with this problem of mine. ? I declared Layer 1 as "Draft" and Layer 2 as "Dynamic".
These are list of files that I checked.
1. Top copper
2. Bottom Copper
3. Top soldermask
4. Bottom Soldermask
5. NC Drill file
Please help. Thanks !
You should chang "draft" into "dynamics" or "static". I think it's better to seek help from Mentor support engineer first, or if you are in China, take a training class.
If you aren't Mentor bussiness customer, you may contact xufeng at firstname.lastname@example.org to get know how to get trained and how to buy Expeditionpcb
