Missing components in the library...

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 order all the coponents for m digikey (got an head acke with their web tool..)

 

My coponents are:

• SN74ACC14N: Found it sounds good

• EVU-F3lFL3B14 (potentiometer): even wiht the datacheet I do not find it

 

Sorry, no email adress to send the extended lbr.

• 1N5817 (diode): can not find it...

Use diode.lbr -> device DIODE- with package variant DO41-10 and set the

VALUE to 1N5817.

• 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...

Use transistor.lbr -> device *-NPN- with package variant TO220 and set

the VALUE to BUL704.

• 1N914BTR (diode) was not able to find it...

Use diode.lbr -> device DIODE- with package variant DO35-10 and set the

VALUE to 1N914BTR.

And the list is going and going 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...)

Thank you both for your answers.

My mail adress is abessy@free.fr ;-)

I was hoping to spend more time to design the PCB and less on the components selection but I understand that all of them can not exists. It is just hard from the point of view that I am not doing PCB often (in fact it is the first) nor I am working in the electronic field so I am not fluent with the components equivalence (yet).

But I will get at it then...

Thank you again for your answers.

Just a comment from a guy who does electronics design for >25 years:

Packaging, component selection and the creation of library parts is

boring but it is often 50% of the job. Especially on cost critical

designs. So it is very important to learn the library editor of a new

CAD system very soon. Eagle isn't particularly easy to learn in that

respect but with persistence you'll get there.

Afterwards, when you haven't used the program for a while it is normal

to forget things.

By the way, the Digikey search engine is hands down the best there is,

there ever was. If you learn how to use that (easy) it becomes a

wonderful tool to find electronic parts. And now they also let you sort

by price.

But I will get at it then...

 

En peu du vin rouge, du fromage et la bonne musique ... and it will all

come together nicely

Next question:

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:[IMG]http://i203.photobucket.com/albums/aa14/badbad214/Eagle/Polygon.jpg[/IMG] ) what is the parameter that I shall change?

Works perfectly for me thank you Gary

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

 

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.

on this component from the library how do you know if the pin and gates are numbered as in the datasheet of the component?

SET PAD ON or OFF

or go to Options/Set/Misc menu and look for "Display pad names".
