Hi All,
I'm observing an increasing number of posts concerned with Eagle problems. First of all the full word for the abbreviation EAGLE. It stands for what it really is, an Easily ApplicableGraphicLayoutEditor.
As any software, Eagle of course has some bugs (mainly the autorouter). Getting used to them working with Eagle is fun, even creating new devices.
If you need a sophisticated package don't hesitate to send me the data sheet or a link. I'll be happy to make it for you.
Today's trick: You intend to put some copy protection on your circuit board. A stamp can be easily removed, but how about a component? That's what we're going to do today.
Step 1: Create your logo either on the solder, component or top layer as a package. Use at least one pin for it. The accepted minimum pin diameter is 0.01mm and the drill size 0.001mm. We're going to use that as a connection to the logo. Select octagon as pad shape. Name it "1".
Step 2: Make a symbol just with one pin and nothing else. Use lenght "point". Name it also "1".
Step 3: Create the device using the symbol and advice package, e.g. "logo-s" (logo on the solder side). Connect the pin.
Step 4: Done - Save
Place the device somewhere within your schematic, best on another component pin. It will automatically connected to that net. (Don't forget where you put it!) Do that after the schematic and the board are finished to find a place adjacent to a trace without problems.
Switch to "board" and the logo is there, outside the dimension layer. Pull it to the place you want. Now you will have an air wire to the next trace with the same net name. Disable the "unrouted" (layer19) layer for a clean print. Try to erase the logo on the board. No way to do that! You must delete it in the schematic, and ONLY YOU know where to find it.
Have fun
Regard to All
