'[PIC]: PicStart Plus Warning'

Hi, just a warning to lube your PicStart Plus
ZIF socket, i've just broken mine through wear
and tear it seems. Has done maybe 5,000 chips.

One of the 2 rivets, the one closest to the
lever has worked slightly loose and now the top
plate of the mechanism lifts instead of opening
sideways as it should.

A dab of oil on the rivets (which I had not
realised are both VERY dry and under a lot of
grinding force) has helped it a bit but it is
only a matter of time before it needs replacing
or possibly repairing. :o)

Hi Roman,

Good advice. They can be a real pain to replace too!

Regards,

Sean

One of mine failed exactly that way a year or so ago.  I simply used a
small diameter long screw with a flat washer to replace hold the movable
top of the socket onto its base.

Both rivets failed on the one I just looked at.  There is an oval hole in
the flat portion of the socket on the end where the lever is, with enough
material on the base to hold threads.  All the lifting force is at the
lever end of the socket anyways, so it was worth a try.  The other end of
the socket is not secured but has never been a problem.

I simply removed the loose rivets, then heated a 4-40 screw with a
soldering iron and threaded it into the plastic base, using that oval hole
right next to the release lever.  Using the hot screw to cut the threads
was easier than using a thread tap (which would have required removing the
socket from the PCB).  The holes that used to contain the rivets are now
both empty.

While I had the socket apart, I applied just a touch of white grease on the
inside surfaces where the lever pushes on the plastic as it rotates.  The
idea was to try to minimize the lifting force on the movable piece as the
lever moves.

Its been working just fine ever since.

Thanks Dwayne, that's excellent info. I will pull
mine apart soon and do the same mod you did. :o)

Let's hope the other PicStart Plus users are
oiling up their sockets BEFORE they break...

I wonder if this is typical of ZIF sockets that
have done a few thousand or just the PSP socket
is a bad brand or something?? It's disappointing
to have it fail badly with only infrequent use,
how do "proper" commercial ZIFs hold up??
