= Setting up working layers =<br />
Pcbnew can work on 29 different layers:<br />
<br />
* 16 layers of copper (or of routing of tracks) <br />
* 12 auxiliary technical layers.<br />
* 1 board outlines layer<br />
<br />
The number of copper layer, and, if needed, their names and attributes should be set.<br />
<br />
Unused technical layers can be disabled.<br />
<br />
== Select copper layers ==<br />
=== Introduction ===<br />
Copper layers are the usual working layers used by the automatic router to place and re-arrange tracks. Layer 1 is the copper (solder) layer. Layer 16 is the component layer. Other layers are the inner layers, from L2 to L15. <br />
<br />
=== Select number of layers ===<br />
To enable navigation between layers, it is necessary to select the number of working layers. To do this you can use the menu bar and select Preferences - Layers Setup.<br />
<br />
<center>[[Image:]] </center><br />
<br />
Then select the number of layers wanted, from 2 to 16.<br />
<br />

<br />
<br />
== Copper layers ==<br />
The name of any copper layer is editable. Copper layers have attributes useful when using the external router ''FreeRouter.''<br />
<br />
[[Image:]]<br />
<br />
== Auxiliary technical layers ==<br />
Some are associated in pairs, others not. When they appear as a pair this affects the behaviour of modules. The elements making up a module (pads, drawing and text) appearing on a layer (solder or component), appear on the other complementary layer when the module is inverted (mirrored).<br />
<br />
The technical layers are:<br />
<br />
=== Paired layers ===<br />
* '''The Adhesives layers (Copper and Component):'''These are used in the application of adhesive to stick SMD components to the circuit board, generally before wave soldering.<br />
* '''The Solder Paste layers paste SMD (Copper and Component):'''Used to produce a masks to allow solder paste to be placed on the pads of surface mount components, generally before reflow soldering. In theory only surface mount pads occupy these layers.<br />
* '''The Silk Screen layers (Copper and Component):'''They are the layers where the drawings of the components appear.<br />
* '''The Solder Mask layers (Copper and Component)''':These define the solder masks. Normally all the pads appear on one or the other of these layers (or both for through pads) to prevent the varnish covering the pads.<br />
<br />
=== Layers for general use ===<br />
* Comments<br />
* E.C.O. 1<br />
* E.C.O. 2<br />
* Drawings<br />
<br />
These layers are for any use. They can be used for text such as instructions for assembly or wiring, or construction drawings, to be used to create a file for assembly or machining.<br />
<br />
=== Special layer ===<br />
Layer Edges PCB:<br />
<br />
this layer is reserved for the drawing of circuit board outline. Any element (graphic, texts。ト) placed on this layer appears on all the other layers. <br />
<br />
Use this layer only to draw board outlines.<br />
<br />
== Selection of the active Layer ==<br />
The selection of the active working layer can be done in several ways:<br />
<br />
* Using the right toolbar (Layer manager).<br />
* Using the upper toolbar.<br />
* With the Pop-Up window (activated with the right mouse button). <br />
* Using the + and ? keys (works on copper layers only).<br />
* By hot keys.<br />
<br />
=== Selection using the layer manager ===<br />
<br />
{| style="border-spacing:0;"<br />
| style="border-top:0.05pt solid #000000;border-bottom:0.05pt solid #000000;border-left:0.05pt solid #000000;border-right:none;padding:0.097cm;"| [[Image:]]<br />
| style="border:0.05pt solid #000000;padding:0.097cm;"| The layer manager also allows you to change color layers and their visibility<br />
<br />
|}<br />
=== Selection using the upper toolbar ===<br />
<center>[[Image:]] </center><br />
<br />
This directly selects the working layer.<br />
<br />
Hot keys to select the working layer are displayed.<br />
<br />
=== Selection using the pop-up window ===<br />
<center>[[Image:]]</center><br />
<br />
The Pop-up window opens a menu window which provides a choice for the working layer<br />
<br />
<center>[[Image:]]</center><br />
<br />
== Selection of the Layers for Vias: ==<br />
If the '''Add Tracks and Vias''' icon is selected on the right hand toolbar, the Pop-Up window provides the option to change the layer pair used for vias:<br />
<br />
<center>[[Image:]]</center><br />
<br />
This selection opens a menu window - which provides choice of the layers used for vias.<br />
<br />
<center>[[Image:]]</center><br />
<br />
When a via is placed the working (active) layer is automatically switched to the alternate layer of the layer pair used for the vias.<br />
<br />
One can also switch to an other active layer by hot keys, and if a track is in progress, a via will be inserted.<br />
<br />
== Using the high-contrast mode ==<br />
This mode is entered when the tool [[Image:]] (left toolbar ) is activated.<br />
<br />
When using this mode, the active layer is displayed like in the normal mode,but all others layers are displayed in gray color.<br />
<br />
There is two useful cases:<br />
<br />
=== Copper layers in high contrast mode ===<br />
When a board uses more than four layers, this option allows the design to seen more easily the active copper layer:<br />
<br />
* '''''Normal mode normal (back side copper layer active)'''''<br />
<br />
<center>[[Image:]]</center><br />
<br />
<br />
* '''''High Contrast mode (back side copper layer active):'''''<br />
<br />
<center>[[Image:]]</center><br />
<br />
<br />
=== Technical layers ===<br />
The other case is when it is necessary to examine solder paste layers and solder mask layers, that are usually not displayed.<br />
<br />
Masks on pads are displayed if this mode is active:<br />
<br />
* '''''Normal mode (front side solder mask layer active):'''''<br />
<br />
<center>[[Image:]]</center><br />
<br />
* '''''High Contrast mode (front side solder mask layer active):'''''<br />
<br />
<center>[[Image:]]</center><br />
<br />
This layer is now displayed, and pads sizes on this layer can be checked.</div>Millo
