DSP Stuff

Hmm, I'd have a go at normal SMT stuff but these things have two 
connections per mm! That's 0.25mm pads with 0.25mm gaps between. And 
they're about 13mm on a side. Pretty demanding precision without 
specialist tools. Fabricating a PCB to those precisions and with 
multilayers would also be a challenge.

It's a pre-built board with SHARC, stereo Codec, UART etc. Linked to PC 
via serial port.
