Missing components in the library...

e14 Contributor

Hello,

Still using the free version and still at newby silly question level.

I am creating (at least trying to) my first PCB board which is going to be a PMW. I started by ordering all the coponents from digikey (got an head acke with their web tool..)

 

My coponents are in my ordering list:

* SN74ACC14N: Found it sounds good

* EVU-F3lFL3B14 (potentiometer): even with the datacheet I do not find it

* 1N5817 (diode): can not find it... 9there is of course some close enough)

* BUL704 (NPN) was not able to find it directly but using the number of the datasheet TO-220 whihc was not in the database either I end up finding it using TO220...

* 1N914BTR (diode) was not able to find it... (same thing found stuff close enough after some time but my electronic level is limited)

 

And the list is going a like that on every conponent.

My frustration level in rising, I spent more time looking ofr the components that I will spend on creating the board (step that I have note reached yet...)

 

 

So simple questions:

1) I am doing something wrong?

2) If I am not doing anything wrong where can I find an extended library of components?

3) If netheir one or two are possible, how do you proceed on your side to order components? you try to see if they exist in Eagle then in DIgikey (for example) and then only order them?

 

Thank you for your help

    When I am doing a polygone it does not go around the legs of my components but let behind some incovered spots (I understand that a picture would be clearer: http://s203.photobucket.com/albums/aa14/badbad214/Eagle/ ) what is the parameter that I shall change?

     

    It will be hard to solder it without those "thermals" especially if the

    plane is any significant size. It will just act like an infinite heat sink.

     

    This is more an issue for mass produced boards, but it is possible to

    produce a board which is not hand solderable as well, I've worked on

    some that simply have too much heatsinking to the ground plane to

    desolder a component. That's when you get out the hot air tool or put it

    in the oven and hope it survives!

    Noep but the funny part is when I am connected it is displayed my real neame when I am not only my pseudo...

     

    Thank you for the hint on thermal.

     

    Hum I would not say that the doc is the most user friendly, an example would have been helpfull in it. What is the syntax for the thermal: Poly Thermal On?

    badbad is your real name???

    Help Polygon is your friend, see the paragraph "Thermals"& the others to

    make your polygon best fit

    In my Board when I have launched a "Autorouter SetUp" and do not like the result how do I come back to the previous state? (undo doesn't do anything).

     

    Use the ripup command ( type HELP RIPUP), it can also be restricted to

    certain nets, or all nets, or all nets except certain nets.

     

    I recommend you do your critical routes manually first, save it, and

    then autoroute the rest, especially if you have lots of manual routes,

    then it is easy to start over.

    Very good. We also bake our pizza in the barbecue, over charcoal. Most

    of the time coals from real firewood. Even when it hails.

     

     

    @OP: lay out your board in mm if you wish ( I often do ),

    but keep schematics at 0.100".

     

     

    Yes, except for library symbols. In order for the more complicated ones

    to look good it is important to switch the grid down to 0.025" or so.

    But make sure outlines and pins are on the 0.100" grid.

    Occasionally they have a Camembert that's actually fairly good if left

    outside the fridge for an hour or so. But not very often image

     

    World Market and Trader Joe's are also good places to hunt for tasty

    European cheeses, if you have those store in your area. Bread is another

    story and we sometimes bake our own, in the barbecue.
