CONN1   Onmetics Bilobe 37-pin male flex, MNPO-37-FF-N-ESJ / A28300-037

The connector needs to be staked on the GND side with Scotch-Weld or
similar immediately after soldering/cleaning/test, to prevent the
traces to break at the weak point between solder joint and flex cover
film.  See IMG_0713-staking.jpg.  The GND side is the one with one
fewer pins.

The electroless Nickel-Gold finish on the rigid carrier is less than
100nm Gold, which does not impose any problems for solder joint due
to Gold contamination.
