I have just bought Eagle online, downloaded installed ok, my question is will I get any handbooks or other physical deliveries from Farnell or Eagle?

If no handbook is supplied how do I get old of one?

Hi,
EAGLE calculates a PAD diameter according to a porcentage of the drill size, this criteria is controlled in DRC/RESTRING tab.
In the DRC/Restring tab dialog box you will notice parameter for PADS, VIA and MicroVias. For the PADs, EAGLE compares the value given in the library and the value calculated on the board. EAGLE will use whatever value is greater. To solve this, in the DRC/RESTRING tab set the MIN column to 0 and set the Restring_% to a very low value like 1%. This will force RESTRING to have a value smaller than the assigned value in the library.
Have a GREAT DAY!!!
Regards,
Ed

As a side note, I can get the diameter change to show up if I make it larger than the "auto" diameter, but not if I set it to a smaller than the auto.

Hi Richard,

I've been using for about 5 years and really enjoy it. I'm designing a package for a through hole part with very small pins. When editing individual pads, I can change the drill diameter and the overall diameter, but when I use that package in a part, I see that the pad drill diameter is as specified, but the outer diameter returns to the value I would get from setting the pad outer diameter to "auto".

Since the pins are close to each other, I'm getting many clearance errors in my DRC. Any suggestions?

-Eric

Hi,
The Solder Mask is defined by the TStop layer for top, and the BStop takes care of bottom layer solder mask.
You can manually draw the shapes using wires or polygons of the areas you need exposed on these respective layers.
I hope this helps.

Ed

Hi Richard,

Just upgraded from 5.10 to 5.11. The connection to Newark gets some getting used to.

Laying out a Hittite PLL on FR4, this is a high frequency chip. The layout calls out a MASK OPENING around the pins of the device with no soldermask or paste in this area.

Any suggestions on how to do this?

Thanks,
Tim

Hi Ralph,

the fill in text is fixed, there is no possibility to change the format. If you don't want to see the timestamp you could, for example, cover it with a white/black rectangle so that it is no longer visible.

Richard

Hi Richard,

can you tell me, where the fill in text ">LAST_DATE_TIME" is defined?
I'd like to need it in an other form like ">LAST_DATE" without the Timestamp.

Otherwise, is it possible to give the ">LAST_DATE_TIME" just another format like "YYYY.MM.DD"?

I'm using EAGLE Free Version just for preparing my lessons on a electrical training school.

Regards,
Ralph
