non rectangular pad

Question

The Murata LXDC2HL series part is a micro-sized DC-DC converter with four pads.

One is rectangular with a clipped corner as a orientation marker. I included the land layout from the spec sheet.

Is there an easy way to make this non-standard pad?

Or does anyone have a package design for this part?

James,

The solution is to draw a standard pad or pads as rectangles and then use the polygon tool to draw the "non-rectangle" parts of the pad. Just make sure to use "1 Top" as the layer for the polygon and select polygon pour of "Solid". The net result is a pad with some extra pour adjacent to the pad to create the shape you need in the foot print. You can also use multiple Pads in the foot print and by rotating and overlapping them create the pad you show below. You can then assign them all to the same symbol pin when you create the device in eagle. Connect the pins and pads using the connect button and the you can use the append button to append additional pads to the pin. You would do this if had drawn several overlapping pads to create a unique pad shape which is an alternative to adding a polygon pour adjacent to the pad.

Hope this helps... Sorry for being lazy and not taking screen shots.
