The terms Board Outline and Board Edge are general names used interchangeably to describe the outer edge of the board. Even if the other polygon is shelved, it can prevent this polygon from connecting correctly. But now, when I edit the polygons, they merge with almost everything and not just the net that it should pour over. I took a video for trying to create a polygon, while after placing the vertices, "repour all" or "repour selected" doesn't affect. The edge connector is made of 3 pads. Polygon pours are working perfectly on the external (top and bottom) layers, and I can see the copper in 3D mode. With the polygon still selected, right click and bring up the pop-up menu again. In the Preferences -> PCB -> General, there is an option called Repour Polygons After Modification. By right-clicking over an existing polygon pour in the workspace, and using the Polygon Action » Polygon Manager command from the context menu. Might not work well with pictures, but since most Logos also come in "simplified" vector forms, it might still be an option. The completed polygon pour in Altium To repour a currently unpoured polygon pour after editing, right-click over the pour then use one of the Rebuild commands (or the Set All To Poured or Set Selected To Poured commands) on the Polygon Actions sub-menu (as applicable). On a PCB copper is the main method for connecting different electrical components but that's not it's only use. After pouring, the polygon will be connected to the previously placed track using thermal relief, which we do not need. Select Polygon Actions > Repour Selected to fill this shape with copper. In Altium Designer areas of copper can be defined using three different design objects: Fills, Solid Regions and Polygon Pours. Altium 17, Polygon repour doesn't work, why? On internal layers, the polygons will not fill when within the board region - and the copper does not appear in 3D. This list can be very long (100s, 1000s). How to remove some parts from your groun plane from example.If you want to remove the plane under the coils of others components you can use this command. This rule defines the minimum clearance allowed from design objects that are fabricated, to edges of the board. So when we have a polygon pour we are pouring copper. Polygon Pour Cutout: in the irrigation area to establish copper digging area. 2. level 1. Select the polygon -> Right click -> Polygon Action -> Shelve selected. Updated a legacy PCB with plane and signal layers. Select “Polygon Actions > Repour Selected”, and you will see your polygon pour is now connected to the desired net as shown in the picture below. If you make a mistake simply use your backspace key to remove the last placed vertex. Could you zoom in the part of PCB which is wrong, so we can see the polygons and net names (same as I did in my screenshot, you can clearly see, that between PHASE_1V375 and +1V375 polygons is bigger gap 0.2mm comparing to polygon vs track, that is … What you are calling a "Plane" is really a polygon pour. 12-19-2019, 12:44 AM. Hi, I am trying to create GND polygons, at the start everything was ok, but now it seems that I am doing something wrong. Post-placement settings – all Polygon Pour object properties are available for editing in the Properties panel when a placed Polygon Pour is selected in the workspace. Altium Polygon Pour. Tweet. Select the object in the Primitive List to reveal its options on the right. most likely that connector is so dense the spokes cannot be … « Reply #10 on: October 02, 2015, 03:28:32 pm ». Right-click on the polygon. \$\endgroup\$ – The Photon Jun 29 '17 at 16:26 Two pads are connected. The term edgeis defined in the table below the image. Then of course, I lost all of my work for the previous 20 mins. Once you are finished, right click in the work space to exit the polygon pour mode. But when I try to choose the right Layer which the polygon will be poured on I can not find it. Recently,I’ve been working on a design in Altium. Here are just 4 ways polygons can be used on your PCB: Power planes. #3. Altium PCB Polygon Pour Instructions. I have tried an alternative approach by defining the shape of the board on the Mechanical Layer, and then selecting the shape to do a “Define from selected objects”. A polygon pour is a group design object - that is, it is made up of simpler primitive objects, either regions, or tracks and arcs. In short, these two tools work together in the board design process. Basically, pick the polygon and right click to get the context menus. Select the polygons to be subtracted. Keshav Amla: The simple answer is that we saw some major pain points in the existing electronics design and development approach, relating to signal integrity, manufacturability and reliability of PCBs. Select the base polygon pour, right-click then choose the Polygon Actions » Subtract Polygons From Selected command from the context menu. Tweet. #2. Altium Designer gives you multiple options for creating and placing polygon pours in your PCB layout. Polygon pours are used to create either a solid or a hatched (lattice) area on a PCB layer using either Region objects, or a combination of Track and Arc objects. You have control over the size and shape of the pour, as well as whether it is solid or hatched. It automatically rebuilds your polygons when you edit them. Previously the polygon would connect to the relevant nets and nothing else. To adjust thermal relief settings in Altium Designer, you just have to change a few settings.Details after the jump! On a signal layer, you can place a solid polygon pour to define an area for carrying large power supply currents, or as a ground-connected area for providing electro-magnetic shielding. There are two ways to solve this situation. When I place a polygon pour on that layer (entire board), it won't pour. Matth345. You can create these regions within a layer using Altium Designer’s high-quality CAD tools, or as a custom component. That does not work for controlled impedance calculations. I am not sure what happened with the modified polygon notification that used to appear, maybe they changed it in the later versions of Altium. Just to add another potential way of doing this; adjust the width of the keep-out tracks and re-pour the polygon. Draw a polygon pour around the shape (Place>Polygon pour), select pour over same net objects and disable removal of Islands. In my design I plan on finishing the routing and then restoring the keepout outline for final DRC checks and polygon pour clipping. \$\begingroup\$ A typical cause of this is if there is another polygon overlapping this one. The third one is not … I am designing 4-Layer PCB on Altium and having hard time in pouring polygon. When thermals are ON, parts' pads that belong to the same net as the polygon will not be entirely enveloped by the copper pour, but instead will be connected to the polygon by conducting lines. What are and why use polygons. The type of polygon is the "Pour over same net objects". I noticed that after launching Tools > Polygon Pours > Repour All, Altium doesn't make the connection between one pad of the edge connector and the polygon pour. In Altium Designer polygons are the same as copper. So when we have a polygon pour we are pouring copper. On a PCB copper is the main method for connecting different electrical components but that's not it's only use. Here are just 4 ways polygons can be used on your PCB: In Altium Designer polygons are the same as copper. Re: Polygon not pouring properly. Creating a Polygon Pour in Altium Designer While in the polygon pour mode you will click where you want to place a vertex of the plane that you are creating. Simply I have two internal planes for Vcc and GND and I want to pour polygons on each of them with the right net. 6 - Created polygon for VCC5 net. You have not connected the polygon to any connection.. if you really want to have a dead polygon (connected to NO Net). What exactly doesn't work? The Board Outline … For example, some important networks or components need to be hollowed out at the bottom. Then you can use the polygon manager to create a polygon pour based on your board outline on whatever layers you want and you're done. ; Options/Controls Polygon Pour | Altium Designer 21 User Manual | Documentation Polygon Pour. I am attaching a screen shot. The controlled impedance calculations done by the software expect you to use an actual continuous "Plane Layer" as the next layer under the signal layer. 18.1 Routing 18.1.1 Interactive routing Routing is the process of defining connective paths between the nodes in each net. set to 45 degree angle. Choose Polygon Actions and then either "Bring to front" or … Fill, Polygon Pour, Plane in Altium Designer ... copper irrigation area will not be directly deleted. 05-12-2016, 03:46 AM. Altium Designer gives you many options for creating polygon pours. Altium Designer gives you multiple options for creating and placing polygon pours in your PCB layout. You have control over the size and shape of the pour, as well as whether it is solid or hatched. Altium Designer includes a powerful … a keepout region). Polygon Clearance Rule Not Working. A polygon pour is a group design object - that is, it is made up of simpler primitive objects. Fig. Nothing that unusual or complicated, so I didn’t expect any troubles. This video covers how to easily connect a polygon to a net using just two clicks. This does not work properly either. ; By using the keyboard shortcut sequence H, P, P, Enter. Polygon Manager command, from the main menus. Right-click or press Esc to complete the process. This dialog provides controls to specify the settings for a polygon pour. -> PLane-> Polgon connect style ->. Select the option "Pour over same Net … When placing a polygon pour, one most painstaking select the net to associate with the pour. « on: August 13, 2018, 03:43:25 pm ». But, the polygon pour operation works perfectly on the L1 layer which has been defined as an internal plane layer. Share. I use Altium 19. Needed to add two more signal layers and designated one of them to be a GND copper pour. This is because Altium treats all the copper which you wish to apply the clearance rule to in the polygon as an object which is ‘in’ the polygon object. See the example in the picture below. The 'Polygon Clearance' rule in Alitum. Make sure you use 'InPolygon' and not 'IsPolygon'. After your PCB has been routed and you are ready to pour copper on the top and bottom layers Click the Design toolbar dropdown and select Rules…. Make sure this polygon comes before any overlapping polygons (even shelved ones) in the pour order. If you have your logo in vector form, you should export it as dxf which Altium can import. CircuitStudio, does not have a pour manager tool and so you can work around this by sending polygons forward or back. Either a single clearance value can be specified for all object-to-edge possibilities, or different clearances for different pairings can be defined, through the use of a dedicated Minimum Clearance Matrix. I am also attaching the polygon properties. In EAGLE, you can activate or deactivate 'thermals' on your polygons. In Altium Designer, you can create your planes either as a negative (Internal) plane or as a positive plane (Polygon Pour). First we will look at the process of creating a negative or “Internal” plane. The first thing to do when creating an internal plane is to add a design layer specifically for the plane. The traces on the signal layer are then referenced to that continuous plane. rule editor. To finalize the attachment of the net to your polygon pour, you need to re-pour it. The advantage of a Polygon Pour is that it automatically pour around copper objects that belong to another net, in accordance with the applicable Electrical Clearance and Polygon Connect Style Design Rules. A simple solution exist - select a pad or trace already associated with a net and then select place polygon! For instance, make mech3 your routing layer, draw your circular board shape and then use define board shape from selected primitives. We will now cover the use of PolyGon Pours. on the split-plane layer itself) primitives which have been defined as “keepout” (e.g. The split-planes which Altium pours automatically do not ignore on-layer (i.e. decrease the air gap in your polygon. It just remains an outline.
