10 Years ago I decided to upgrade my (Jewel Green) Supra interior lighting to LEDs. At first I did those poorly using bare LEDs strung across the button rows. They had a tendency to burn out quickly due to vibration, etc. So then I experimented in making my own discrete circuit boards. This took forever to make as I had to lay all the circuit paths and then Etch them.
Then I decided to have them professionally made. But the issue with these were I had to individually cut each item out with hole saws. Again, this took forever. So I asked my son, Marshall, to see if there C&C machine at his work could possibly cut them out. So this was a huge time saver. Like 50% less time.
Here is a video of them being cut out: http://97supraturbo.com/LEDs/20131127_100747.mp4. This video is showing the HVAC round boards and all the Instrument micro needle LED boards being cut.
