Homebrew PCBs

I spent the last hour reviewing old threads about tt and have a question about making component pads thicker using Eagle.  The process I use is design the board using Eagle and print the board on Staples Basic Photo paper.  I prepare my copper board using a kitchen scratching pad, then rinse and dry.  I actually use a iron used for ironing monocoat on airplanes.  It heats up well over 300 degrees and it is easier to see where you are ironing. I iron for around 4 to 5 minutes, cool the board with cold water and peel the paper off.  The paper comes off with minimal effort under running water. Usually the board looks very good, except for the fact that I lose about 10 percent of the pads. I get a half moon on the pad, but not good crisp circles.  I think the thickness of the pads is too small.  What I would like to do is to make the pads thicker (Between the hole and outer edge, sorry I don't know the terminology). What is the best way to make the pads bigger (Thicker)  Thanks.  Carroll

Dear Billshat44

in Eagle (haven't done it for years!) you select a "Change" and change pad sizes to what you want.......up to over 0.5" if necessary!!

Look in help, you should use PAD as a search and you will find all the infos you need, including:-

The pad shape or diameter can be selected while the PAD command is active, or it can be changed with the CHANGE command, e.g.: 
CHANGE SHAPE OCTAGON .The drill size may also be changed using the CHANGE command. The existing values then remain in use for successive pads. 



I hope this helps,



Andy

hi

to make the pads bigger, edit the foot print in the library
to do this flow the steps

1- from the control panel go to (file ---> open ---> library)
2- select your library
3- from the tool bar use the package batten
4- select the component you wont to edit
5- from the action tool bar use chang ---> diameter

You can only do it this way in the library editor, not the PCB layout.

You might be able to trick it with design rules....

This is getting rather old. Andrew, would you please fix your spam filter, or edit the subject line when it adds the "probable spam" text to it?

I've asked you many, many times. Surely there is a whitelist you can add the list address to in order to prevent this.

Respond off-list.

Eagle is optimized for board production houses, which means plated
though holes and the like.  You do want bigger pads for home
production.

I've made a custom library (make library, open it, using the control
panel, go to the desired part browsing through libraries.  Right click
and "copy part to library".  Then go change the pad diameter in the
custom library.)

When you upgrade, the old libraries are overwritten.  5.x allows you
to replace a part, which will preserve your layout while allowing you
to select a part from another library (yours).  

That's also a good thing for your own custom parts.  You'll find that
you'll create them.  Eagle libraries are good, but not perfect.

Change the part in the library, then run "update all libraries from
your design".  Changes will be automatic.  Be certain to run the ERC
and DRC to see if the rules have been violated.

A larger annular ring is the technical term. More meat round the holes is a 
colloqial version.

Does this helps?

Dear AlienRelics 

  of course I will do that for you, no problems.

  But you could have been more exact earlier and I would have complied earlier.....I simply did not fully understand what you were on about, I thought you meant in the text!!!!

  Andy

A big thank you to all of you who responded.  Now I think I can make boards that I don't have to fill in with a grease pencil 8-)
