MOTM

The MOTM kits don't come with dip sockets.  I prefer to socket the ICs just 
incase I need to replace or swap a chip for any reason.  I have a lot of dip 
sockets laying around doing nothing.  I know if I just go ahead and socket 
the chips, I will be told afterwards that I should not have.  So I might as 
well ask the question before doing so.  Is there any reason I should not 
socket the ICs?

Thanks,

Sockets cause leakage currents *unless* they are gold plated "screw machine"
types
like in the '110.

Also, Why socket a 25 cent chip?

Usually, the 25 cent chips don't go bad.

I usually socket the ICs using turned pin type sockets.
You hear a lot of stories about the poor reliability of the cheaper sockets, but
a story worth mentioning is that a Scanning Electron Microscope (\ufffd35,000 2nd
hand 7 years ago) I used in my day job was recently dismantled for shipping off
to another location. I took a peek inside at the PCBs - all the ICs (and there
were a lot of them) were socketed using the cheap type of socket. Didn't have
one electronics related problem with it all the time I used it.

But I stick to the turned pin type just in case. Give it a few years & we'll see
if it was a mistake or not...

Yeah.  I have all kinds of equipment with socketed chips, probably not the 
highest quality either, and never have problems.  Besides, just loosening a 
chip and reseating it should correct any long term contact problem.  I take 
comments about current leakage, etc., with a grain of salt.  But since I 
counldn't find any 8 pin sockets in my boxes of misc electronic parts, I 
figured I'll just forget about socketing.
