Keep autorouter from routing in an area? - Page 1

content: I have a section of polygons for the power section but I cant seem to keep the autorouter from using that area and cutting up my polygons. The only work around I have found is putting a mask on the tRestrict/bRestrict, run the autorouter, move the masks to the tKeepout/bKeepout, ratnest and tweak the traces. Now if I have to ripup, i have to redo it all over again. Seems like there has to be an easy way?

Trace top and bottom layer at the same time? - Page 1

content: This is a relay and a terminal block.To double the current handling capacity, I thought of running the traces from both top and bottom layers.To do it, I routed them on the bottom layer and then ran a identical wire on the top layer (because Eagle won't let you route an already routed signal).In this particular case it is not much of a hassle, but I was wondering if there's a more automated way to run traces on both sides of the board?

timestamp: June 28, 2019, 06:50:13 am
content: Hello,I've come across similar and it's a pain. EAGLE imports exactly what is provided to it but if the DXF doesn't contain a closed shape then it will not detect as a correct board outline. I've had to resort to manually tweaking the start/end points of segments in order to make them match the connecting segments which can be time consuming.The first thing I would try would be to see if you can get Solidworks to close the outline before it's exported to DXF as it sounds like the problem is the output from Solidworks is not closed. I'm not a Solidworks user so I don't know how this might be done.Alternatively, you could import the dxf into Fusion360 and then use the EAGLE/Fusion360 integration to pull the board outline from there which should bring it in correctly.Best Regards,Rachael

Thermal pad questions - Page 1

timestamp: April 03, 2019, 12:34:44 pm
content: I've got a polygon with thermal enabled and some 6mm x 6mm buttons where the ground pads have thermal pads. What options do I have in eagle (old 7.3) to lessen their connection to the polygon? They are not high current and don't need the 4 traces to ground. My hardship is that they can be a pain to solder because the heat is being leached by the plane itself. If I turn the polygon thermal option off, then they are solidly connected to it with no breaks which is even worse. I was thinking of some way to separate them from the ground plane and perhaps I just route a wire from them to it if that is possible. Ideas?

timestamp: April 03, 2019, 01:58:26 pm
content: The width of the thermal relief connections between polygon pours and pads connected to them is directly proportional to the line width used for the polygon. If you want these to be less then reduce the line width of the polygon until they are at your desired size.Best Regards,Rachael

author: macegr
author_rank: Regular Contributor
timestamp: October 03, 2018, 04:21:55 pm
content: All "square" holes on a PCB will automatically have rounded corners, because they'll use a spinning router bit to mill the slot.You can specify slots with 0-width lines on the Milling layer. You can leave the corners square or round them, but either way the corners will still be rounded. If they're located completely inside an area of top and bottom copper, most PCB services will know that it is a plated slot. I can confirm that both OSH Park and DirtyPCBs correctly interpret and produce oddly shaped internal plated slots.

That may or may not be suitable for the component you are trying to place.

Specifically, I'd like to be able to mitre corners of traces and terminate them in a 'square' end as opposed to the default rounded one. Is this at all possible? The only thing I've been able to think of doing is using the free form polygon tool to create a signal in the shape I want and using that, although it would take longer to route this way and is harder to control the dimensions.As a side note I am not using the latest version of Eagle (8.6), mostly because I was fed up with the constant barrage of updates forcing me to manually install all my libraries each time. If the newer versions offer any tools which might help, I suppose I could upgrade.

You are right, you can't change the end caps and although you can miter traces you can't do it in the way I think you are needing for this type of application.Quote from: ElectronicCat on December 15, 2018, 12:50:52 pmI would use the latest v9.2.2 if I were looking at this as the move tool has been enhanced a lot in v9 and now will preserve angles when moving, including with polygons which will help a lot if you are trying to create specific shape polygons for an RF design. Combine this with good use the main and alt grids and you should be able to create most shapes quickly and easily.With regards to your issue with manually installing libraries. You don't need to do this. Have your own libraries in your own custom location and specify this in the directories setup, then every new version installed will see these libraries and there is no need to reinstall.Best Regards,Rachael

But as you can see its gaping the SMD connections . And some like the output tab on the regulator are just cut off. I cant even directly connect the center pin to the tab directly. I assume this is due to the masks in the parts but is there a way to override this? Or a I creating the rail the wrong way? I am using the polygon tool and naming it for the single name like +5V, GND, etc. Is that the correct way? I would really just like the whole pad to be right on the rail without a mask and these tiny traces.

It's actually very easy.Once you copied the frame/library and renamed it to something new, you open the frame in the device editor.Than you open the symbol (the actual frame) in the symbol editor. Now make the changes you want.There are some predefined words that will be automatically replaced by Eagle with actual data like:>DRAWING_NAME (filename)>LAST_DATE_TIME (date/time when the file has been modified)>SHEET (sheet number)For example, if there's written (in the symbol) "Sheet: >SHEET" (without the quotes),then, after adding the frame to the schematic, there will be written "Sheet: n" where n is the sheet number.After adding the frame to your schematic, you fill in the empty boxes with text strings.

content: It looks like you are using the walk around mode of the route tool. That icon means it cannot go where you want it to go because it will cause it to violate the DRC requirements. It'll likely be a clearance or keep out rule being violated. Switch it into manual mode (the icon next to the walk around icon (currently selected) in the top toolbar when the route tool is active) and you should see live DRC violations appear as you route to the pin. Open up the DRC window and see what the actual errors are and this will tell you what the problem is.Best Regards,Rachael

I have never looked for it...)Do you really need the 3D view? For drawing schematics and having PCBs manufactured, it is not required, and it does not matter at all if the parts look different in the 3D view than the ones yo will populate later. Unless you have very special needs (e.g. modellng something in detail in 3D, because you want to fit it ino a tight three-dimensional enclosure) I would just ignore the details of the 3D view.

I don't think you can mirror a component but keep it on the same layer, as that would mirror the silkscreen and put it on the wrong layer (like the solder side of a SOIC foot print, with mirrored pin markings).Perhaps if you explain what exactly you are trying to do?If they are TH components, such as resistors then you can always populate them on the other side of the board.

content: I've been trying to figure out how to create a library of all the components we use across all our PCBs (~30) -- and only those components: no unused packages or symbols.Reasons:Our pick-and-place machine would be much easier to set-up if, for example, all resistors come from the same package.Need to add attributes to each component for inventory and purchasing. There's already been a few effups where the wrong package of a component were bought, or used on a PCB.Want to make all the text sizes uniform across all parts. (Already have a script for this.)I already have a custom library with all the common stuff, and custom parts. I'm trying to cull this down so that eventually we'll be restricted to using only parts (and especially packages) in this library.This topic wasbrought up before. However these methods copy everything, not just the used packages.I found an interesting ULP: "lbr-merge" for concatenating libraries if exporting only used packages of components (However, Export Libraries exports everything, or only packages with no other data). There doesn't appear to be much else for this sort of thing.Is there something I'm missing? Or do I have to go through each component and delete each package manually?

Clearance Bug in Eagle 7.1 / 7.2 - Page 1

content: Hi everyone,I've encountered a really annoying problem in Eagle 7.1 and also 7.2.Here’s what I did:Ages ago I started a PCB layout in Eagle 5.x. In the meantime I switched to Eagle 7.1 and made a few changes to the PCB. Today I made more changes, saved the file and ran the DRC. Now DRC suddenly tells me that there are tons of clearance errors. I checked the clearances manually and they are certainly within the specified rules. Even when specifying 0mil between adjacent tracks, the DRC still fails. I quickly upgraded to Eagle 7.2, but the problem still exists.My backed up file from last week works fine with the same DRC settings from the DRU file.Any ideas what’s going wrong here?Best regardsOndre

Eagle hangs at end of autoroute - Page 1

content: I've had this problem with eagle for years, I think I even asked Cadsoft about it once but never resolved the issue. Anyhow, maybe somebody here knows:Occasionally after the Eagle autorouter finishes and I click the "End Route" button, it hangs for some period of time. Greyed out screen in the board editor, spinning circle. This almost always is related to using polygons. More complex boards result in a longer hang. It's been hung for about 10 minutes on a relatively complex board that I'm working on now. Windows task manager shows eagle is using 10% of the CPU. I have a six core system, so I assume that percentage is aggregated across the cores and means one core is mostly consumed.Does anyone know, 1) what the heck it's doing, 2) how to prevent it from doing this, and 3) how to abort it short of killing the process.Thanks,Scott
