Tin plating is mentioned for corrosion prevention purposes...
Using Tin... problematic.
BRITE tin plating .... creates nearly ideal conditions for tin whisker growth. I have seen brite tin plating grow whiskers in a clean room environment (no need for moisture or temperature cycling)- whiskers a 1/2 inch long! and through plastic!
Created crazy problems... the whiskers are soooo thin, (but highly conductive) they are hard to see without magnification. easy to break, but grow back. Nothing but intermittent problems for the circuitry involved.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
