I have been making a small, (top and bottom copper only) board. Using the "iron the toner from the paper onto the copper" method.
I have the challenge of working with version 6.4.0 at the shop and version 7.1.0 (probably) at home.
(The shop version has autorouter, my home version does not.)
I am wondering about modifying the pad layout and dimensions. ( I don't have a full set of tiny drills... 0.040" and 0.020" are about it.) How should this be done? I tried, but did not get sit right. See below.
The default size for R-US_0207/7 (R-US_) is a 0.031 hole and a rather small pad diameter maybe 0.040 or 0.050 inches with a pin spacing of 7.5 mm.
I modified on my home computer and made the pad bigger, and answered a query about it and now it it is bigger, like 0.070 inches. The trouble is, I have modified all the pads on the board AND changed the library definition.
The software at the shop doesn't recognize this modification. I did the modification by clicking on a resistor, selecting "open package" in the menu and modifying a R-US_0207/7 package to have a different pad diameter.
I had a couple attempts at this and so I am not sure what I did. The end result is the device name is the same but I have changed the package name and dimension. I have not saved the mod to a new library part.
How can I get back the original package? How can I properly edit, modify and save a new package to the library?
Screen shots are from the software at the shop, the older 6.4.0 version...
This message #01 , with 4 resistors with the bigger pad.
and message #02
The way the library looks now is this. ( I modified the name of the 0207/07 package, obviously.) message #03
I just learned how to load libraries when starting EAGLE up, so I am a rank beginner. A step by step, with no jargon is where I am at.....
Thank you all very much!
