What is tPlace Layer in EAGLE?

# Layer 21 – tPlace This layer contains the top side silk screen. It usualy contains the component outlines. Care must be taken not to cover any ares that have to be soldered. It is also possible to create additional and rather betterlooking silk screen for documentation purposes in layer 51, tDocu.

What is tPlace?

tPlace is a layer used for visible lines (for example, component outlines) that will be laid as silkscreen in the manufacturing process. tDocu is used for documentation, such as mechanical dimensions.

What is the name of Layer 17 in EAGLE?

Standard layers

What are the different layers in EAGLE PCB?

Each ‘layer’ in Eagle has a dedicated number, and these layers are used to separate all the types of content that make up your PCB or your parts: These layers contain documentation details (layer 51), actual manufacturing info such as the ‘paste layer’ (layer 31), the copper layers for you pads (layer 1), etc.

Is there a silk screen layer in tdocu?

It is also possible to create additional and rather better­looking silk screen for documentation purposes in layer 51, tDocu. This may indeed cover soldered areas, since it is not output along with the manufacturing data. This layer contains the bottom side silk screen (see layer 21 for more details).

What does the dimension layer on an eagle board mean?

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. These layers indicate spots where the fab should avoid putting the purple solder resist.

Where are tracks not to be placed on a PCB?

Tracks should not be placed in this area. This layer is the bottom side keepout area for tracks (see layer 41 for more details). This layer is the keepout area for vias. This layer contains the conducting through holes. It is usually used for pads (of through hole components) and vias. This layer contains the non-conducting holes.

How do you delete measurements in Eagle?

How do I delete messages in Eagle?

First, make sure you are in the symbol editor and have the “origins” layers enabled (from memory – I’m not at a machine with Eagle to check). This should bring up a little + by each text. Then you can use the delete tool on those.

What is dimension error in EAGLE?

Dimension errors indicate objects are to close according to the setting you. have established in your design rules. Learn what each of the DRC settings mean and you will understand the errors. and be able to make proper decisions on the nature of the error.

How do I resize my EAGLE board?

You can adjust the granularity of the grid, by clicking on the GRID icon — . A 0.05″ grid, and 0.005″ alternate grid is a good size for this kind of board. EAGLE forces your parts, traces, and other objects to “snap” to the grid defined in the Size box.

What happens when you delete a wire with Eagle?

If you select wires (tracks) or vias belonging to a signal with the DELETE command three cases have to be considered: The signal is split into two parts. EAGLE will generate a new name for the smaller part of the signal and keep the previous name for the larger one.

How can I delete two wires at the same time?

If the DELETE command, with the Ctrlkey pressed, is applied to the joining point of two wires, these wires are combined to form one straight wire. For this to work the two wires must be in the same layer and have the same width and line style, and must both have round endings (in case of arcs).

What happens when you delete a group in Eagle?

Clicking the right mouse button deletes a previously defined GROUP. After deleting a group it is possible that airwires which have been newly created due to the removal of a component may be “left over”, because they have not been part of the original group. In such a case you should re-calculate the airwires with the RATSNESTcommand.

Is there a way to delete layers in DRC?

Use the RIPUPcommand to convert an already routed connection back into an airwire. The DELETE command has no effect on layers that are not visible (refer to DISPLAY). The DRC might generate error polygons which can only be deleted with DRC CLEAR.
