I’ve got these libs… thanks. They are converted from an other CAD software (Eagle I guess). You will notice that these libs can’t be viewed or managed by the Lib management tools which are in portugese or so (Mod2mod, Lib2lib, …) for some reason.
To illustrates what I was saying, on the www.kicadlib.org, most of the SMD parts which can be seen from this link have the issue. For instance : http://www.kicadlib.org/modules/d2pak.png http://www.kicadlib.org/modules/tssoic28.png http://www.kicadlib.org/modules/vqfp80.png http://www.kicadlib.org/modules/3M_Serie_2500_SMD.PNG You see the silkscreen on pads ! no way to industrialize a PCB from this. It must be modified… Same remark on some libs I’m using from <http://library.oshec.org/> http://library.oshec.org/ like the vishay 153 caps, diods, transistors or power transistors… this one is correct : http://www.kicadlib.org/modules/lm4674_llp_sqa16a.png After a deeper look at these additional libs, I think most of the SMD part numbers have the issue L So what I’m doing now is to pick up the component I need from these libs, and then duplicate it into a own lib and modify it ! I’ve spent all the day doing that and I’ve not finished ! This is a nightmare ;-) For this project I guess I’m going to continue but for new projects I may switch to another CAD system. Altium Designer looks good and is not so expensive. It’s a pity as I like Kicad and the job done for the development is fantastic, but … these 2% details makes me wasting my time so my money… Best Stephane De : [email protected] [mailto:[email protected]] De la part de Andy Eskelson Envoyé : jeudi 21 janvier 2010 17:40 À : [email protected] Objet : Re: [kicad-users] libs silkscreens unusable I understand, there is not really much that can be done about that apart from a reedit. The only thing I can suggest is to have a look at some other libs. If you have a look here: http://library.oshec.org/ There are 1000's of converted libs and mods, and looking at some of them the outlines do keep clear of the pads, (at least on the sides needed for solder on the dpacks I looked at as examples.) At the top of the page is a link to download the whole lot, about a 12Mb download. That might save you a bit of time. The above site is linked via http://www.kicadlib.org/ then via http://per.launay.free.fr/kicad/kicad_php/composant.php Both the kicadlib and Pierre Launay's sites are worth bookmarking Andy On Thu, 21 Jan 2010 14:18:25 +0100 "Stephrac74" <[email protected] <mailto:stephrac74%40wanadoo.fr> > wrote: > Hi Andy, > > > > In fact this option only enables you to add or not the pads footprint on the > silkscreen. > > > > The problem is different.
