Hi guys, I have been doing bigger and bigger layouts using gschem and PCB recently, and I've gotten pretty used to working around various quirks. However, I have run into a problem which does not seem to have any solution beyond modifying the code for PCB to add some capabilities. I would like to make a footprint for any of the Lumileds LUXEON power LEDs to add to my project. They have three basic housing designs, from oldest to newest the I/III/V, the K2, and the Rebel.
The Luxeon K2 requires a hexagonal soldermask hole inside of a larger filled copper area, as seen on page 14 of http://www.lumileds.com/pdfs/DS51.pdf The Rebel requires some more fancy soldermask work, in addition to curved arcs and odd shaped filled areas. Fabbed PCB photo on page 11 of http://www.lumileds.com/pdfs/DS56.pdf and documentation on pages 5-8 of http://www.lumileds.com/pdfs/AB32.pdf. However, "Elements may contain pins, pads, element lines, element arcs, attributes, and (for older elements) an optional mark." Thus, if I wanted to make a hexagon, curves, or large filled areas as part of an element, I would have to approximate it manually using only a large number of pads, which is far from optimal. How difficult might it be to add one or more of these capabilities into both the file format and software, in order that I can use it for Luxeons?
