Here you can change the following board features.
- Layer Count
- Power Planes (only available if a multi-layer board is selected)
- Solder Mask
- Silk Screen (only available if solder mask is selected)
- Material Thickness (only available on a 1 oz Cu, 2 layer board with solder mask)
- Fished Copper Weight (only available with a .062”, 2 layer board with solder mask)
- Lead Free (immersion silver)
Note: When changing Finished Copper Weight to 2.5 oz PCB123 we change the default space and trace to .013”. If you later decide to switch back to 1 oz Cu PCB123 will leave the trace and space set to .013”. To adjust this you can refer to the How to set PCB123 net width and spacing post.
