A simple RS part number system

    Agreed.   Options at present seem clunky.  Even when you find a part with Ecad that has a schematic and footprint it requires a long winded process to load it.  The files for DesignSpark are just one file but still has to be first downloaded then found by browsing from the library then load each of 3 components separately.  Maybe there is another way but it's not immediately obvious?

    If you do not require the advanced features of ECAD such as fractioning, try Library Loader, from the search engine select your part, download and it is automatically saved to your library and the symbol is attached to the mouse cursor for placement. All in a few clicks.
    The first 2 items here give the details https://designspark.zendesk.com/hc/en-us/sections/115000311505-PCB-Part-Library

    There is an older article from 2017 here which also has a video

    Thanks.  I'll try that and feedback.  Almost too many options sometimes!  Simple is good... 

    Update : I got this when trying to access the installer ...

     

     

    BTW what is "fractioning"?

    Try from here https://www.rs-online.com/designspark/pcb-part-libraryhttps://www.rs-online.com/designspark/pcb-part-library

    What link did you use and I'll check and report it if there is a problem.
    You do need to set an account with Samacsys as it's all on their server, but I use the same as my DS account.

    Fractioning is where you may be using a larger component such a programable logic array or even a uC with configurable funtionality on I/O pins. If you know what you require you can group the schematic symbol pins by function and these canl be placed on your schematic where required.

    Most of my projects are simple so I don't use this, but am beginning to explore.
    Just found this link and think the video shows it. https://www.rs-online.com/designspark/ecad-part-wizard

    Looks like the link is working now...  Actually I already had the Library Loader Ecad tool installed and had been using it manually.   I eventually got the automation to work but should note the video misses making clear certain important steps to get this to work.

    Significantly in the Loader dialogue the downloads folder must be set to the same folder as the browser uses by default.  In my case it is Users\Geraldo\Downloads.

    I also changed the "Your Ecad tool" "settings" to specify Design Spark format.  Not sure if this is critical but seemed the right thing to do?

     

    Finally.  After selecting "search for parts" and finding the part in the componentsearchengine.com and clicking the green icon, here marked C0

    It takes you to another page where you need to click this download button.

    Ok - now if the DSpark schematic is open then the part can be inserted with the mouse.  So still a bit of a fiddle to setup but now seems to work fine, so long as the part you are looking for has existing drawings..  :)

    Note.  It did work using the samacsys option for searching via the Mouser web site option option crashed.  So this system seems never straight forward... 

    I actually think now it will be easier to use a manual method in the long term and not bother with the Ecad Library Loader.  I found that if I choose "add parts from file" in the DS library I can just go directly to the downloaded zip file and select design spark folder, and it then loads all parts of the component, which is quicker than I was doing it previously.  It also means I can choose any supplier who has the cad files in their search engine and not have to deal with other software.

    Anyway - thanks for the response which got me on the track.  Even if I end up back where I started. 

    I'd also note that I prefer to search for parts from familiar suppliers rather than use the embedded library files in DS.  I find that there is just too much stuff and it is very time consuming to search through, with apparent multiple listings of equivalent parts which easily creates confusion.

    The normal sequence I use is have DSPCB open and then launch Library Loader. It will minimise to the system tray and closes when you shut down the PC. You have to open it from the system tray if you need to do anything further with it - that's just FYI.

    The video was a high level video just showing the overall features. The full details are in the first two FAQ's in the link https://www.rs-online.com/designspark/pcb-part-libraryhttps://www.rs-online.com/designspark/pcb-part-library

    This covers the download and library path.

    I think if you get used to the Library Loader functionality you will find that the best method in the long run.

    If you download parts which are zipped to your download folder without DSPCB launched you can also extrat them later via Library Loader using the "Open ECAD Model" which then automatically extracts the DSPCB part to your library.

    A word of caution, when selecting the part to download via the icon there is a C0 to C5 rating. I tend to only use C2 and above and check just to be certain it is correct, which it normally is!

    Thanks for the follow up.  Gradually getting there.  I did find a problem with downloading directly from RS with some parts.  I received a *epw file format which DesignSpark does not recognise unfortunately.  So it can be frustrating when trying to use parts that fit my budget or are more readily available.  For instance RS Pro components often don't have data.  I feel I may have to just buy samples of the components, then make custom files for them, or modify existing ones.  Also some crashes from Ecad when specifying RS don't help and add to the confusion...  :(

    BTW the reason for preferring finding parts on the RS site is because the search engine is better.  Ecad just give a long list of parts which often don't really suit the purpose because they have a different pin count or some other aspect depending on how they are specified.  So it's a long winded task to check each one.

    Yes the RS site can be a problem with models. I do beta testing for DS and have raised the issue which DS are trying to resolve.

    I also assisted DS with this FAQ https://www.rs-online.com/designspark/parametric-search-with-designspark-pcb but as you point out not all parts have a model and you also don't know until you get to the RS part page... My suggestion was to have the model link in a search column or with the description.

    Out of interest do you recal the part number you had the epw file with?

    I don't think I have ever had a crash with ECAD, but you could pass the details to support.

    Part numbers from RS with epw files :

    d15s13a4gl00lf

    dal15sbtk2ns

    107-15261232102

    SN74LV14AD

    The last one is not an issue since it's a standard soic package so I can use a generic footprint...

    Be nice if the software designers, suppliers and manufacturers could get together and agree on a standard...  :)

    @Gerald, looking back at posts I think you should change you Library Loader libraries setting to "User" rather than "DesignSpark" just to ensure there is no risk of these being overwritten by a reinstall.

    Thanks.  Actually a good idea since I have downloaded a few parts already, but then had to seek them out and transfer to my user library anyway...  Transferring is a bit messy since the sub files have to be moved separately it seems, or else they get left in the original directory.  :(

    I used Ecad a few times today and getting slightly more used to it. Now if only they had Digikey there as well...
