What are you going to fix it to? A PCB is thicker than that...

Is an external chip needed? You can do multiplexing with the Arduino, it just takes more programming effort.

Its actually going to soldered onto a 0.8mm PCB.

The chip package is mostly plastic. If you splay the legs out you can probably grind it down very thin by rubbing it on sandpaper. It won't be easy, you'll probably wreck a few while you're finding the limits...but it could work.

...or you could use the Arduino to do the multiplexing.

Thats actually just got me thinking, I may just use a second atmega in a qfn package as the driver, and use the first (main) arduino to send serial commands to the second...
