http://www.instructables.com/id/Killer-PCBs/ This instructable
demonstrates the process for making printed circuit boards with
features as small as 0.005 suitable for LQFP or QFN ICs using
negative dry film photoresist. This will enable you to handle just
about any kind of integrated circuit available--even ball grid array!
Pictured are boards with a TSSOP-14, QFN-40 packages using a .65mm
pitch and zero insertion force flex sockets with .5mm pitch.
