What is the name of layer 17 in Eagle?
Layer 17: Pads Keep in mind that you’ll rarely need to tinker with this layer, as through-hole pads are automatically generated once you place down a through-hole package.
What is the name of layer 31 in Eagle?
tCream
Predefined EAGLE Layers
| 1 Top | Tracks, top side |
|---|---|
| 31 tCream | Solder cream, top side |
| 32 bCream | Solder cream, bottom side |
| 33 tFinish | Finish, top side |
| 34 bFinish | Finish, bottom side |
What is Eagle Keepout layer?
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 silkscreen outline?
Silkscreen Outline This layer will become the silkscreen once the board moves to assembly. When possible, the silkscreen outline should be an exact copy of the assembly outline. On smaller components like SOTs, resistors and capacitors, etc, the silkscreen layer should surround the entire body of the component.
What is silkscreen in PCB?
Silkscreen is a layer that uses ink traces to identify all the PCB board components, test points, parts of the PCB, warning symbols, logos and marks etc. These shapes, numbers, and letters really aren’t some new language. They can also communicate the function of each of the pins.
What is a pad in Eagle?
The PAD command is used to add pads to a package. When the PAD command is active, a pad symbol is attached to the cursor and can be moved around the screen. Pressing the left mouse button places a pad at the current position.
What is Eagle TStop?
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 a silkscreen layer?
Silkscreen is a layer of ink traces used to identify components, test points, parts of the PCB, warning symbols, logos and marks etc. Essentially a detailed PCB silkscreen can help both the manufacturer and the engineer to locate and identify all the components. The ink is a non-conductive epoxy ink.
How is silkscreen applied?
Mostly, the silkscreen is applied to the component part of the PCB. Nowadays, it is also applied to the soldering part. The silkscreen printing helps both – the manufacturer and the engineer to identify different parts easily. Typically, non-conductive epoxy ink is used for silk screen printing.
What is silkscreen made of?
Currently, synthetic threads are commonly used in the screen printing process. The most popular mesh in general use is made of polyester. There are special-use mesh materials of nylon and stainless steel available to the screen-printer.
What is SMD in Eagle?
The SMD command is used to add pads for surface mount devices to a package. When the SMD command is active, an smd symbol is attached to the cursor. Pressing the left mouse button places an smd pad at the current position. Pressing the center mouse button changes the layer onto which the smd pad will be drawn.
Which is the bottom layer in Autodesk Eagle?
Rather, EAGLE will use Layer 1 (top), 2, 15, and 16 (bottom) to bring it all together. Layer 16: Bottom Just like Layer 1, this layer contains the copper on the bottom of your board, whether that’s from copper pours or individual copper traces. Components placed on the bottom of your board will also have their pads placed here.
How can I add more layers to my silkscreen?
In this case, navigate to the silkscreen top and bottom section in the left side of the screen and click the button in the lower left corner of the layer list. This will let you edit the list and add or remove layers from the job.
How does restricted layer work in Autodesk Eagle?
By default, when you fill in a polygon with copper over a restrict layer, the restricted section will remove any copper. This layer also comes in handy when using the autorouter in EAGLE, as it can prevent traces from being routed in defined areas. vRestrict will indicate where vias should not be placed,…
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).
