Eagle Software Query

[fightstar]

how to create in version 4.09r2? i've succeeded in creating the package , and the symbol but when i go to create the device and click on "add" i just cant find the symbol that i created in order to make the connections between the symbol and the package .

ps : when i go to look at the libraries i only find the package not the symbol besides him as all the components are

Hi fightstar,

the Eagle version you are running is really not of any importance. I'm running 3.5.5, 4.5.0 and 5.5.0 wich are almost the same with a few minor changes. (I also ran version 2.0.0 in the early 70s)

I prefer version 3.5.5 since it has less bugs than any other follow on version. Addionally it's colours are bright blue (solder side) and bright red (component side) compared with the pale colours used in succeeding versions. (not to be changed)

To create a symbol I guess there is nothing to tell about, but may be you missed an important detail: "SAVE".

Eagle goes strange ways sometimes. If you expect a symbol in alphabetic order it might appear miles behind the expected letter/number combination. (not experienced using version 3.5.5)

Just dig through your library and if the symbol is saved properly it will appear on the selection list sooner or later.

The problem is made by using ASCII code when putting (and sorting) names in the libraries, instead of logic sequence. (0 has a higher value than 1)

So, once again: dig through the library where you created the symbol. You'll find it 100%!

hi i ve done my eagle steps for my schematic and the board as well i ve got 100%, now i need to convert it to excellon and gerber formats in order to order an industrial panel with my schematic on it , how ?

thanks

I have not done it.

About all I know is that you need to run CAM job(s).

EDIT: It looks like the stuff at sparkfun is specific to their operation. But there is a tutorial on the SparkFun or BatchPCB site on the subject.

i knw now that the cam jobs on eagle are behind the conversions but i coudnt understand the steps to work with , could anyone help me on waht can i do to convert it ?

Hi fightstar,

an Exellon file is nothing but a CNC drill file.

It contains a list of tools (referring to drill bit sizes without actually stating the drill diameter) and the x-y coordinates of the drills in subdivisions pointing to the selected tool.

E.g. tool size 1 refers to a drill diamter of 0.4mm in your PCB-layout. Using a 0.6mm drill for tool no. 1 all holes in the sudivision of the list will be drilled with 0.6mm diameter.

From the control panel select CAM-jobs and select Exellon. Load the board and click perform job. The program will generate a file named <boardname.drd>.

This is what it will look like:

Not all of the information is necessary to drill a PCB. The PCB-manufacturer normally deletes certain lines of the file (lines two (M48) and three (M72) as well as the last line (M30)

thanks man i really appreciated your help man , thanks a lot

Hi
since this thread appears to have a number of Eagle queries, does anyone have any idea why I am getting odd pad sizes ?
Basically, I have defined an e-line transistor device which has quite close pads (1.27mm apart). In the device definition, they appear correct, but when used on a board, it looks like the diameter is being ignored and always uses auto (I have done a library update). I am using 4.16

Have I missed something obvious ?

Mike

 

[MikeyC]

Think I have found the answer - its the DRC applying a minimum size to the pads making them bigger.

 

[Mr RB]

For that application you could keep the pads the same size, just change the shape of pad 1. That's probably a more "normal" way of doing it.
