In eagle cad the wire size of the copper pour also sets the thermal trace size? - Page 1

content: Re Eagle cad copper pour wire size.I was penalizing some boards and I set the copper pour wire size to zero to allow for easy placement, then I found that all the thermal wires had become zero.So obviously that's the wrong work flow, but is there an easy way to stop the copper pour extending beyond the size of the dimension layer?or is it just a mater of having to pulling the copper pour back from the edge of the dimension layer?Harry

timestamp: October 20, 2016, 07:42:24 pm
content: Hello Hazzer,I hope you're doing well. In the DRC > Distances > Copper/Dimension parameter. This parameter controls how close the polygons can get to the dimension layer( aka edge of your board). This would be the correct way to pull copper away from the edge.With that said, zero width polygons are in general not a good idea, they generate tons of CAM data with little benefit. Our rule of thumb for polygon width is use the largest with that will give you acceptable polygon resolution. As you have also discovered the width of the polygon controls the thermal connection, if you need a thicker thermal connection you can just draw in the wires manually.Hope this helps.Best Regards,Jorge Garcia

content: Quote from: ulix on February 20, 2016, 05:00:14 pmThe help command is a command to open the manual. You add an attribute in the form of a topic.So, if you enter the command "help mirror", it will open the manual at the position where the "mirror" commandis explained. The mirror command is used to mirror objects. In the pcb or package editor, this means it will be puton the opposite layer.In Eagle, al tools and commands can be entered as text with options.So, every icon you normally click on, to activate some tool, as it's own command name.One way to easily find the command name is to keep the mouse stil above an icon.A small tooltip will popup with the name.

I have already made several boards without the use of these commands, and probably did much more complicated stuff.This is the benefit of the Forum.

content: You use zero width wires on the Dimension layer to specify the outline. You can use the Miter tool to make the curves.Generally speaking, you'd rough out the outline using straight lines of the correct lengths as specified by the datasheet. Then you'd use the miter tool to add the correct radius to each line.You can also stick the outline in a custom component to make it easier to re-use. In that case you'd delete the default outline when you make the new board, then add the custom component instead.And don't forget to print it out and check the actual physical fit before you spend a bunch of time laying out the board

ULP for fattening tracks to resemble isolation milling? - Page 1
Forum section: electronics / general

author: matseng

timestamp: October 09, 2015, 09:23:08 am
content: As discussed elsewhere a common trick to preserve the potency of the etching solution is to make floodfills/ground planes on the pcb even if they are not strictly necessary for the design. Quite often this ends up with a lot of floating islands (aka orphans) that really should be stitched together - and for a single sided pcb this means extra jumper wires on the top.Another way of achieving this would be just widening all traces to fill up all available space on the pcb, giving a pcb looking more or less like isolation milling. This could be done with a lot of polygons roughly shaped like each track and then have different ranks on them to get the isolation. Or having precisely shaped polygons with the isolation already calculated.Voroni shapes would work as well.Is there an ULP that does this or something similar? I know there's plenty of ulps and scripts that makes gcode out of it, but I'd like to have the end result inside Eagle so I can generate gerbers.

copper expansion in library - Page 1

content: I'm designing a library part for a reverse protection schottky diode (SMD). The part is going into a bunch of different boards that will be designed by a bunch of people. I want to provision in to the part some extra thermal relief. This is so that anyone that uses the part automatically has the same added features. I want to do this by expanding the copper underneath the pads but without affecting the size of the stop layer. This way the diode is easier to solder down.So far i've tried making the pad larger but that makes the stop larger too and i'm not sure how to make it smaller. I've tried making a polygon under the pad but there is no way to name it and the DRC gives error when the part is placed in a board. The same thing happens if rectangle is used as well.how do i make the pad copper larger but not affect the size of the stop?

How to group parts in PCB editor - Page 1

author: vini_i
author_rank: Regular Contributor
timestamp: July 30, 2015, 01:26:31 pm
content: I was wondering is there a way to group parts in the PCB editor semi permanently. What i'm drawing my question from is how MS Office can group art elements. For example, a smiley face is drawn using a circle and some lines. Every part of the smiley face is highlighted, right click, and select group. From there forth the multiple pieces of the smiley face are now one object and can be moved as one util the un-group us used.The reason i'm asking is i like to put together small blocks of a bigger board first and then put the blocks together. The best example is the Microchip MCP73811 lithium ion charging IC. The data sheet gives a very nice layout with resistor and capacitor placement, ground and power plane placement for heat sinking and via placement. After i put the block together i can use the group tool to move what i designed into the boarders of the PCB. After placing other things into the PCB i want to move the charging block over to give more room to rout things but using the group tool to select just the components of the charging block becomes very difficult with other things in the way. If the components could remain "stuck" together it would make moving the block substantially easier.

content: Hi all,still using Eagle 6.4 (just as info) and have a small nagging problem.I had a large three sheet schematic and pcb and wanted to make another smaller pcb with only half of the parts.So made a new project and I copied the old schematics to that folder and renamed it to the new project name.Now comes the thing I am stuck with:I moved (copy + paste) all necessary parts from the schematics pages 2 and 3 to one page 1, and then I deleted (removed) the other schematic pages (2+3).I did a renumber parts on sheet 1 and added new parts.What happens is that for instance I had 7 connectors K1..K7 from which K3..K7 were on pages 2 and 3 that are now deleted. I add a new connector, do a renumber parts command and the new connector gets number K8. Not K3Manually renaming that connector works most of the time but that is pretty stupid esp. when going to 40+ resistors renaming.Has anyone a solution for this issue?Thanks

Unfortunately the gentleman that originally created the board is no longer on the team.Both my team member and i had finished our revisions and were days away from sending the board out to fab. I was tiding up the silk screen and to fine tune things i like to upload the board file to OSHpark. i'm looking over the silk screen and i find that the board has 4 big holes in it. i start investigating and find that two parts need board cutouts that neither i nor the other team member were aware of and we both have things run in those areas. i found the holes in the Milling(46) layer.what perturbed me is that there were no warning sines that something was wrong. the DRC did not flag anything. the ground pours were not pulled back from the openings. nothing. if i hadn't looked at the board in OSHpark we would have made paper weights.should those cutouts be moved to the dimension layer or are they correctly on the milling layer?i'm using a DRC file that was made for OSHpark specifically, can something be enabled to catch if something is in the milling layer?is there anything that i'm missing? because even looking in the gerber files we generated for Advance Circuits the holes were not there.
