content: Hi guys!I am brand new to the Eagle EDA package and I was wondering if anyone had a footprint for this CUI part: CUI Inc. SJ-43614-SMT-TR.There's a link to the data sheet here:http://www.cui.com/product/resource/sj-4361x-smt.pdfI don't quite trust my own skill set yet and this part is a bit tricky for a newbie, so if anyone else has used this part before, I would greatly appreciate it if you could give me a hand.Thank you!Justin.

content: Do you need it to be a "mid mount", how the part sits down in a cut out of the PCB? the 1.2 mm "ears" are smaller than most of the cheap and cheerful pcb houses standard tool racks will support. Yes you can get it made or do your own after the fact.If you only need a jack you might try SJ-43514-SMT-TR,

content: Sorry, I'm not trying to offend anyone here, but really?Drawing footprints should be a part of standard everyday PCB design flow, not much different from placing a component or a trace.If any PCB design package makes it this awkward, the software is fundamentally broken and completely unusable for designing PCBs."Special" and even custom parts come along all the time. Drawing them cannot be avoided, and you shouldn't even try to avoid it. Just learn it, or if it's really too tedious, change the software package NOW before using too much time to learn it. I have heard this is a huge problem with Eagle, but it's only hearsay as I have never really used Eagle myself. Some people get the job done using it, others get frustrated.I'm using a poorly featured, obsolete, little-known PCB package myself, but making a component footprint is a few clicks of "place pad", "place line", "select region", "make component", done. It really SHOULD work like this in any proper software.

content: Quote from: Siwastaja on April 14, 2016, 07:01:26 amI agree.Quote from: Siwastaja on April 14, 2016, 07:01:26 amImho, this has nothing to do with the kind of package. No offend but this is a "beginner's" problem. They are eager to start designing a board and skip learning the basics whichstartswithlearning how to create a symbol, footprint and a library.We are using Eagle for many years and creating symbols and footprints is a breeze. I do it all the time. Honestly, I don't use the default libraries of Eagle.But, yeah, youhaveto read the manual the first time and practice...Back to the footprint of the op, the only thing that makes it a little particular is the pcb cut-out. This needs to be drawn in a separate layer and you have to confirm with your pcb manufacturerthe possibilities and tolerances for the milling.

content: Quote from: Siwastaja on April 14, 2016, 07:01:26 amGenerally I agree with you but the part he has specifically chosen has a complicated cutout that mates with the board edge as well as foot print which is not so easily done in eagle.

Should not be very hard if the datasheet has some point to use as zero reference.Tip: set grid to 1mm.

content: Quote from: lincoln on April 14, 2016, 03:30:46 pm... is also easy with Eagle.Quote from: lincoln on April 14, 2016, 03:30:46 pmWhich is not related to Eagle but related to pcb design in general, so don't blame Eagle for that.Anyway, pay attention. Depending to the boardhouse, different situations exist.First of all, and before starting a design, setup the designrules correctly. Most boardhouses provide DRU files for Eagleso that's easy.Now, some boardhouses accept cut-outs or milling in the dimension layer. If that's the case, usually the tolerances arepretty big and not all shapes are possible. Also, it's usually not allowed to have copper near the edge.For that, there's the milling layer which is used by most boardhouses to do more exact milling/cutting and/or allows youto have copper near the edge of the board. This service usually comes with extra costs.

content: Eagle user here.I have used those connectors as well as a number of USB and BNC mid-mounts. I don't put the PCB cutout in the footprint - it put it in the PCB outline because it is part of the mechanical design. I just put the pads in the footprint and ignore the various DRC errors that tell me the copper is too close to the edge, etc.That method forces the correct placement of the device which has to match up with a hole on the enclosure when it is all done. It is not difficult, but Eagle part creation in not intuitive. You just have a make a few parts to get the process and that is it.Food luck.
