What is Keepout error in Eagle?
Keepout is used when you don’t want components placed within an area, like edges of a board, or where your heatsink will be placed. Restrict polygons make sure the specific copper layer cant be placed within the polygon. We use them to keep other traces away from noise sensitive traces and parts.
What is tCream?
Layer 31-32: tCream/bCream These layers contain all of the solder paste data for your surface mount components. You’ll usually find this layer being used by your manufacturer to make stencils for printing solder paste before assembling any parts.
What is the name of layer 31?
tCream
Predefined EAGLE Layers
| 1 Top | Tracks, top side |
|---|---|
| 30 bStop | Solder stop mask, bottom side |
| 31 tCream | Solder cream, top side |
| 32 bCream | Solder cream, bottom side |
| 33 tFinish | Finish, top side |
What is TStop layer?
The TStop layer is for solder mask, the thin coating that prevents copper on the board from being exposed except for the areas where desired. The TStop layer leaves apertures slightly larger than the pads so that the copper is still exposed in case of misalignment when producing the PCB.
What is Keepout in PCB?
A PCB keepout is an area on a circuit board set aside by the designer where no external components, copper traces or other board elements should enter into or cross.
How do you hide an eagle layer?
I’m using the Eagle 9.4. 2 Free version and in there, you can simply click on the “Layers” button to get a menu that displays the layers and you can simply click the “eye” icon to hide or show them.
What is the Oz layer?
An OS layer includes the software and settings for the operating system that you deploy in layered images. The OS layer is necessary for creating: Platform layers. App layers. Layered images.

What is a Keep Out layer?
A keepout is the name given to an object that blocks or prevents the placement of copper objects within an area. A keepout can be defined as a fence (in essence, a wall around the area to be protected) or they can be defined as a solid area of keepout that completely covers the area to be protected.
What is the keep out zone?
Glossary Term: Keep-Out Zone The area on or near a CPU or GPU processor that the circuit board layout design can not use, due to thermal management components, cooling, and mounting constraints.
What are layers in Eagle?
Understanding layers in EAGLE PCB Software
- # Layer 1 – Top. The first layer contains the top side tracks and the top side copper pour (if used).
- # Layer 2 to 15 – Route.
- # Layer 16 – Bottom.
- # Layer 17 – Pads.
- # Layer 18 – Vias.
- # Layer 19 – Unrouted.
- # Layer 20 – Dimension.
- # Layer 21 – tPlace.
What is a grid in Eagle?
The GRID command is used to specify the grid and the current unit. Given without an option, this command switches between GRID ON and GRID OFF.
Is solder mask necessary?
Always. Without soldermask, solder can migrate off the pad, on to the traces or down into vias. The amount of solder paste we put down on a surface mount pad is based on making a good solder joint and having solder mask to prevent that migration.
What is a Keepout track Altium?
A track is a primitive design object. As well as the standard track that is used for design tasks, there is a second type of track available, referred to as a track keepout. A track keepout can be placed as a layer-specific keepout object or an all-layer keepout to act, for example, as a placement or routing barrier.
Can you tell a Roomba not to go somewhere?
Like its rivals, the Keep Out Zones can be set within the iRobot app by pinching and zooming a box over a specific area of your home map, and, for as long as they appear red on the map, you can rest easy knowing the robot cleaner won’t enter them.
