CadSoft EAGLE 7.5.0 Lock Bug Fix
We use them all the time to fill blank space on a PCB with copper connected to ground. Go to the board so we can lay down a polygon. A polygon with a dashed line will appear picture 3.
This will now be a solid copper area on your final PCB. For example if you wanted to beef up a power trace. Polygon properties Right click on the edge of a polygon and select properties. From here you can customize the polygon. It also affects some properties below. Pour Here you can select between two versions of fill for inside the polygon, solid or hatched. We only use the solid fill option in our projects. Isolate This is the clearance between the polygon and neighboring objects, such as other traces, pins, and other polygons.
Leave as much room as you can. Ranks Rank determines if one polygons if above or below an overlapping polygon. Assigning a lower rank to one polygon will make that polygon dominate the other as seen in the pic above.
When using a ground fill over the entire board it is important for it to have the highest rank so other polygons can be drawn. Thermals With thermals on, a pin will connect to the polygon through small traces extending from the pin center in 4 directions. Thermals make soldering easier, the part heats faster because the heat is not dissipated as quickly. We usually use thermals. We only turn it off on high power traces that require more conductivity between the pad and the polygon.
The ground plane connects all the ground pins on a PCB automatically, which usually makes routing easier. It can also reduce electrical noise on the board.
Power planes Power planes are no different than ground planes, they just carry a power supply instead of ground. We use these for fat power traces where the board will carry a lot of current.
