Altium polygon pour connection. The document provides instructions for using polygon pours in Altium to fill empty copper areas on the top and bottom layers of a PCB design with ground. A Polygon Pour is also a solid region that can have an arbitrary number of vertices, but is subject to design rules that remove copper in service of changing how it is filled, how it connects to vias and pads, and how it might have portions removed depending on polygon pour sequence (defined in the Polygon Manager). "Pour Over All Same Net Objects"? You can also simply draw a track there to connect it with the polygon - that is what I would probably do here (I would maybe draw a polygon pour cut out in the chip area and draw tracks manually to connect pins with polygon the way I would like to have them). The Top Layer (left) and Bottom Layer (right) of the PCB shown in Single Layer 3D mode. Beginning with general preference settings for Polygon repours in the PCB Editor, the menus are designed for intuitive use. Make Layer [4]L4 the active layer. When created from regions, each isolated section of copper is a region object. (See your second image. Those areas involve high current and I would like to fully fill the gaps on the whole area. Let’s create a polygon connection for a VCC5 net located on this layer. This is confusing, because the "Test Queries" button indicates that, pretty much anything in the query, is Not only is the polygon not connected to the 4 GND pads, it's also not connected to all the vias. Share me EEVblog Electronics Community Forum » Electronics » PCB/EDA/CAD » Altium Designer » Polygon pour direct connect rule Jump to: AD21 only puts "tracks" to tie the polygon pour to the matching nets. Simple - this mode is the generic setting for how pads/vias connect to a polygon pour. Q: What is the difference between a polygon region, polygon pour and polygon plane Simple - this mode is the generic setting for how pads/vias connect to a polygon pour. Position the cursor, then click or press Enter to place. And if the objects match (which it looks like they would here). If there are two networks of VCC and GND in the drawn area, the Fill command will connect the elements of the two networks together, which may cause a short circuit. A typical cause of this is if there is another polygon overlapping this one. Region – region objects are used to create polygonal-shaped copper regions, polygon cutouts, board cutouts, and cavity definitions. Altium sometimes doesn't connect polygon pour and pads with same net names. This article provides Altium has no problems connecting traces and polygons, it's simply whether you have "pour over all same net objects" selected in the polygon properties. The capacity to freely customize these shapes allows designers to meet strict manufacturing standards, component footprints, and optimally balance solderabi I've made boards and seen more that use polygon pours that flow over pads that connect to the same net. 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. Explore Altium Designer technical documentation for Electrical Rule Types and related features. I am using Kicad. Also make sure your polygon is large enough if you have the removed dead copper or islands box checked. The top region of the dialog contains a list of all polygons that are placed on the PCB. If I try to pour a pol In Altium Designer, you can define how vias and pads connect to polygons with a design rule. This is confusing, because the "Test Queries" button indicates that, pretty much anything in the query, is Share me EEVblog Electronics Community Forum » Electronics » PCB/EDA/CAD » Altium Designer » Polygon pour direct connect rule Jump to: A polygon pour is a group design object - that is, it is made up of simpler primitive objects, either regions or tracks, and arcs. On the pads (which I will be soldering) I need to have a relief connect for the polygon pour of the same net, but I need a direct connection on the Vias of the same net. WhoKnewKnows , 05-02-2021, 07:26 PM For this instance, it looks like the polygon's minimum neck setting is preventing the polygon from I am working with net ties in altium to link different ground signals. Altium Designer has such a design in its Polygon and Power Plane command structure. On the Change the "Pour over same net polygons only" setting to "Pour over all same net objects" under that polygon's settings. EEVblog Captcha We have seen a lot of robot like traffic coming from your IP range, please confirm you're not a robot cifically for them. After launching the polygon pour placement command (Place » Polygon Pour), the cursor will change to a crosshair, and you will enter polygon pour placement mode. For example, copper irrigation need to be mulfycrowh , 05-02-2021, 12:20 PM Hi everyone, I use Altium 19. g. Board edge radiation: I usually place a via fence around my board edge and connect GND (i hate this word, prefer Return) polygons on all layers to it. ) Also, the polygon clearance from GND shown in the first image looks weird since it appears to only be creating clearances from the trace and not the pads. From individual inventors to multinational corporations, more PCB designers and engineers choose Altium software to design and realize electronics-based products. Author Topic: Polygon pour connection for vias (Read 3116 times) 0 Members and 1 Guest are viewing this topic. It describes editing the clearance rules to increase spacing, then using the polygon pour tool to draw boxes around the board on each layer to fill empty copper areas with a ground connection. Unfortunately my copper planes are not attaching to any of the IC pads. Explore Altium Designer 23 technical documentation for Polygon Pour and related features. It's not my first time using them, but at the moment i'm doing whole pcb's with them, mainly for thermal reasons. Polygon Pour: Cut the copper pouring area. When the crosshair appears in the design space, press Tab to pause placement and edit the parameters of the polygon in the Properties panel. The reason the pour hasn't completely overwhelmed the pad is the line elements thru the pad are keeping it back some based on the line-to-line clearance rule! The solution is to create a polygon plane connection rule, which makes that polygon be a "No Connect" rather than "Direct" or "Thermal". The influence of the Keepout collection on the Polygon Pours can be seen clearly when the layout is viewed in Single Layer 3D mode, as shown below – Top Layer on the left and Bottom Layer on the right. Author Topic: Trace vs Polygon pour for power rail (Read 17239 times) 0 Members and 1 Guest are viewing this topic. technical documentation for Polygon Pour and related features. In the Net field, use the drop-down to select VCC5. Thanks for help. I have other vias, outside the small copper pour area of layer 1, that connect to the ground plane on layer 2. However, I was tasked with making minor changes to an old board that I didn't design. If I try to pour a pol Differences and usages of Fill, Polygon Pour, and Plane in Altium Fill means drawing a solid copper sheet, connecting all the connections and vias in the area What altium version are you using? I had the same issue with Altium 24. Explore Altium CircuitStudio technical documentation for Polygon Connect Style and related features. So I got the direct connection for the vias at ground pours and ground planes. Under the polygon manager, create a new polygon connect rule. Then hit F10 to rep our. Thanks in advance for your valuble suggestions. I always flood my outer layers where possible, but not by using one fat polygon over my whole board. It looks to me as though your footprint has a keepout rule which is preventing the polygon from pouring inside that area. x. Choose Place > Polygon Pour from the main menus. My net ties seem to work, no drc error, and I can link traces between them and objects of the same net. BUT with the direct connection, the via's that are connected to pins are no longer connected to the top gnd-pour, as seen in the second picture. Hi, I am working on a high current buck converter circuit using Sic466 Switching Ic with integrated mosfets. 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 electromagnetic shielding. I have two design rules for "polygon connect style": In Polygon Connect Style, configure a separate rule for vias using “Direct Connect”, and set it to a higher priority so it takes effect first during copper pour to via connection. The via connection style (relief or direct) is: defined by the applicable Polygon Connect Style design constraint for polygons, the applicable Plane Connect Style design constraint for power planes, with direct connections for solid regions and fills. Whenever i place a pour, Excluding the components or pads has no effect here. Explore Altium Designer 21. Wondering how to make a ground plane? Some helpful tips for creating ground planes in your PCB design using Altium Designer. I am working with net ties in altium to link different ground signals. x and pretty sure it was a footprint issue. May 7, 2024 · Polygon won't pour to connect the same net copper objects inside the outline There can be several factors that can prevent polygon pour from establishing connection with the same net copper objects, such as: incorrect Net Options and Polygon Fill Mode attributes, Polygon Rebuild option in Preferences, incorrect or incomplete Layer stack Polygon pours are used to create copper geometries on your board. What’s more, the interaction between pads and polygon pours— the thermal relief connections—has moved beyond standard rules to demand tai e and solder masks. This will get rid of your problem. However, my Vin net is high voltage, and needs to have a 1mm clearance. FAQ Why sometimes it takes a long time to copper pour Check that the PCB has a large number of polygon pads, which generally appear in the PCB imported Altium Design files, and if so, manually modify them to Round or Rectangle pads. How to Change Polygon Connect Styles in Altium Designer | PCB Layout Altium Academy • 25K views • 3 years ago If you need to convert a fill or region into a polygon in Altium Designer, the "Convert to Polygon" command won't work directly since it only recognizes tracks, arcs, and lines. It can be done quickly using the Polygon Pour Manager dialog, which is accessed by selecting Tools > Polygon Pours > Polygon Manager from the main menus. Just to prove polygon doesn't apply in the first case, I excluded everything but the polygon in question; now nothing pours direct-connect (including the targeted polygon itself). Fill: Draw a solid copper skin that connects all the wires and vias in the area, regardless of whether they belong to the same network or not. WhoKnewKnows , 05-02-2021, 07:26 PM For this instance, it looks like the polygon's minimum neck setting is preventing the polygon from I recently started extensively working with polygon pours. Learn how in this video, as well as how to customize the thermal relief width, number, and rotation On this PCB I want to use it to connect two ground planes (polygons with nets GND and AGND). A polygon pour is a group design object - that is, it is made up of simpler primitive objects, either regions or tracks, and arcs. How can I fill the complete pad with polygon pour ? (I dont know the correct question in english) I am using Altium Designer 17 In Altium, when I draw a polygon, it automatically leaves a gap around copper of a different net. Make sure this polygon comes before any overlapping polygons (even shelved ones) in the pour order. Differences and usages of Fill, Polygon Pour, and Plane in Altium Fill means drawing a solid copper sheet, connecting all the connections and vias in the area I use Altium 19. Advanced - in this mode, you have the ability to separately define thermal connections for thru-hole pads, SMD pads, and vias, respectively. As you can see, CircuitStudio doesn't connect the pads to the polygons. Currently those vias have thermal relief on layer 1 and 2 but I would like to change the polygon connect style of those vias to direct connect. Polygon Pours avoid placed Keepout objects. mulfycrowh , 05-02-2021, 12:20 PM Hi everyone, I use Altium 19. Attached below a screenshot showing the issue. What I do not like about it is that you only get those (maximum of) 4 little traces of copper that actually touch the pad - is there a way to have pours that completely cover the pad in copper, like in the second image? Excluding the components or pads has no effect here. If you move the polygon over other ground pads will it work? That will tell if you if it's a footprint or polygon prolem. Learn how to create a polygon pour in Altium Designer and understand why it’s important in PCB layouts. Polygon Pour – polygon pours can be created from region objects or tracks and arcs. As they are poured, polygons automatically allow for clearances around electrical objects belonging to a different net, connect to objects of the same net, and fill irregularly shaped areas. - double check pour settings e. . with regards, Gok First one is with and second is without thermal relieves. A Polygon Pour (Place » Polygon Pour) that is placed on a signal layer creates a polygonal (multi-sided) area of copper that can either be solid or hatched. The Place pulldown offers commands to draw and pour a polygon, along with enabling cutouts to the shape or splitting the pour. Press the Tab key to continue polygon placement. Hiding a polygon is similar except that the polygon is not hidden from the DRC and net connectivity analysis engines. May 4, 2023 · A Fill or Solid Region is a solid region similar to a polygon pour except it does not have options for fill style (like hatched), pour sequence, or connection style to vias and pads. Even if the other polygon is shelved, it can prevent this polygon from connecting correctly. I am using a polygon pour to connect to the pads in the image shown. Jan 21, 2025 · To place a polygon pour directly, first switch to the required layer. Both polygons are set to "pour over all same net objects". gbssw, nwzcp, 7yzz17, gyilf, b49lyq, 5zxsmn, wnbobh, tcpnk, eudbw, x0rnpj,
