Re: gEDA-user: Question about PCB


If I've got an area with pins, pads, lines, vias.... and want to fill the areas between the lines to reduce EMV - how can I do this?
If I use the polygon/rectangular tool, I will procue a short cut, because all the area will be filled.
What can I do?



I think you are using a very old PCB tool. Use the latest CVS, or
snapshot release.

In the settings menu set "new lines arcs clear polygons". And it'll
clear. Use it with caution, since thermal connections are not checked
against DRC.




My tool is the release from the CD - and it works.
It was my failure trying to connect lines first and place filling areas after doing that. (Because in the PCB-programs I know you have to do this like this) So I thougtht that it don't works...
With your hint I try to place an area first and draw then lines - and it works..

;-)
Thank you!

The other question belongs to producing new Footprints - in SMD - in
the case when I have to define pads with strange withs and distances. If I want to generate a footprint - the old way should not



That's true. Grab a paper and a pen, draw the pads, calcualte the width
and the length of the wire, and draw it on the PCB layout. The rest is
the docs.


Yes, but am I rigtht - that I am only able to draw pins like lines? - with the same restrictions for the with?
I only see the options to change the with of the lines (pads) by increments of 10 mil.
What shall I do, if I need a Pad which is not in mil?

be used - and the new way is bounded to the grid of the PCB tool.
So was the question: Is it possible to place elements directliy as x/y



You mean newlib and oldlib?


I think, it doesn't matter which way I am able to use - I want to create my own library with either copys of known parts or new parts.
But the problem is, that I do not understand how I can create some footprints like TQFP 144, or these new modern very small footprints...
With the newlib I've got the problem of the mil-grid and whats about the oldlib?
