[sdiy] IC socket reliability

[Richie Burnett]

Definitely specify turned-pin if you anticipate more than a handful of 
device insertion and removal operations.  The cheapo folded sprung metal IC 
sockets quickly loose their springiness after a few insertions and bad 
connections start to show up!

I don't have any MTBF failures or anything at hand but I'd think that 
datasheets for example parts should be able to quantify reliability 
benefits.

(In general I try to avoid any un-necessary electrical connectors in 
anything I design, and would solder directly to the PCB unless it was 
something like an EEPROM where you anticipate removing and refitting as part 
of the life cycle.  In my experience it is usually connectors that cause 
reliability problems with age (surface oxidation), vibration, or at extremes 
of temperature and humidity.)

-Richie,
