Teensy 3.0 – Test Fixture Development and PCB comparison via Hack-a-day…

I’ve spent the last several days building and programming the “bed-of-nails” test fixture that we’ll be using to test every Teensy 3.0 board.  The hardware was designed many weeks ago, but the PCBs only recently arrived.

The pins are part numbers S-100-K-3.5-G and S-50C-TL-3.2-DG-S.  Both can be purchased from Mouser Electronics.  The 2 boards were ordered from Laen’s OSH Park   http://www.oshpark.com/  Laen’s PCBs work particularly well, because they’re from a USA-based manufacturer with much higher accuracy drilling than other low cost services.  For placing the test pins, this matters greatly.
