What does the copper layer in Eagle mean?
Using the Polygons tool on the copper layers will generate a “copper pour”, which can dramatically simplify connecting your board. For more details on ground planes in Eagle, see our Using copper pours page. This layer indicates the copper ring around a through-hole pad.
How do you calculate copper pour in Eagle?
Left-click to draw polygon edges and double click to close the polygon. Once the outline is drawn, it appears in dotted lines: Click the RATSNETS to calculate the copper pour: The board should be updated. When the board is modified, the copper pour is not always recalculated.
How do you connect copper pour to net?
Select the POLYGON tool. If the copper pour needs to be attached to a net, you can enter the net name straight after selecting the tool and validate with the Enter key: It is still possible to modify the connection by right clicking on the edge of the polygon, in the contextual menu, select NAME.
Which is the top layer of solder paste?
These layers are ordered with the assumption that 1 represents the Top layer, and 16 represents the Bottom layer. As such, most 4 layer CAM jobs assume you’ll use 1 (Top), 2, 15 and 16 (Bottom). These are the solder paste layers, which are used for making solder stencils.
How does the ground plane layer in Eagle work?
For more details on ground planes in Eagle, see our Using copper pours page. This layer indicates the copper ring around a through-hole pad. Unlike the Top or Bottom layers, Pads will generate a copper on both sides of your PCB. It’s generated automatically when using a footprint that has a through-hole component.
What is the role of the dimension layer in Eagle?
The Dimension layer also serves an important role for Eagle’s DRC checking of copper pours. Eagle will automatically enforce the Edge Keep Out DRC rule, and push copper pours away from any line on the Dimension layer. Since Eagle expects the board edge on this layer, our service uses the Dimension layer to generate a board outline gerber.
How does Eagle enforce the edge keep out DRC rule?
Eagle will automatically enforce the Edge Keep Out DRC rule, and push copper pours away from any line on the Dimension layer. Since Eagle expects the board edge on this layer, our service uses the Dimension layer to generate a board outline gerber. Our fab will then use that layer to cut your board out from the fabrication panel.
