Well Ramon,
That is why they are called 'compliant leads'. They still store displacements 
elastically, thus the cyclic strain range is nbot reduced. however, the 
reason they work so well is that they drastically reduce the cyclic stress range, 
thereby reducing the area of the cyclic hysteresis loop which is a measure of 
the cyclic visco-plastyic strain energy which determines the cyclic damage done 
to the SJ.
Whow--long sentence, but technically, if not grammatically, correct.
So a QFP SJ is very reliable--very compliant leads, and a TSOP os not--very 
stiff leads.
That's enough for a Friday.
