I always thought this was because of "chip-creep"
over time chips (ICs) will work their way out of sockets...
Hi
It is interesting that you mentioned this. This was
a real problem at one time, created by automatic
chip insetion.
When one puts a chip into a socket with tention spreading
the legs, it will tend to pop out of the socket.
Why it does this I'm not sure because you'd think that
with the lead spread out they'd tend to pull the chip
into the socket.
The solution for this is to straighten the leads so
that they go straight into the socket without side
tention.
Those nice little insertion tools that keep some
tention on the leads should only be used for soldered
in parts and if used for sockets, one should straighten
the leads first. It doesn't hold nicely in the tool
but part won't work out of the socket over time.
