VCF/Midwest - Just 3 weeks away

[Patrick Finnegan]

In case you hadn't noticed yet, this year's Midwest VCF is just under 3
weeks away - April 26 and 27.  We still are working on getting
exhibitors and speakers for the event - drop me a line if you're
interested in either.  Sign up to exhibit soon!

Vince Briel will be at the event this year, doing a Micro-KIM and
Replica One workshop.

I built a Replica-1 (first version) a couple years ago; INSANELY fun kit,
and Vince is a GREAT guy.

Micro-KIM? Great, now I need to go off to see what that is all about...

Thanks!

Lionel (who also built a Replica-1 ;^)

Micro-KIM info is here[0] (I'm going to order one tonight, either pre-built or kit (I'd like ot build it, but I'm not sure I'll have time anytime soon...)

Any of the soldering geeks out there have any suggestions for
re-attaching a male molex-type connector to a mylar ribbon cable?

I have 2 cables from iPod click wheels where one of the pins has been
pulled loose from the logic board connector.  I'd like to try to repair
them before plunking down the cash to get replacements.  The connector
has legs on it similar to an IC.

It looks like it might re-flow if it was pressed together and re-heated,
but was wondering if anyone had any better suggestions.  I have basic
soldering equipment here, but no access to a temperature controlled iron
at the moment.

Thanks--

I would suggest that you should borrow a temperature-controlled iron.

Anyone know what the melting point of said mylar is?  Is it too low to
use a hot air rig?

Peace...  Sridhar

Can you be more specific?  Molex makes about 20,000 different
connectors, of which about 500 can attach to ribbon cables!   If you
take a picture and send it to me, I'll let you know how to fix it (or
will be happy to fix it for you if it can be done).

It's the black connector on the upper left in this photo.

I can give you a macro photo if that's not good enough.

The pins look like those on a small IC, where the leg is an "L" with the
vertical pin going up into the plastic friction-fit connector, and the
short leg flattening out on the end to attach to the copper trace in the
ribbon.  There are 12 pins total.

Thanks--

Since someone asked off-list, it's from an iPod Mini.  I'm trying to get
a couple of broken ones working for my brothers.  I also have a Photo
(4G color) and a 5G video that are dead, so if you have any parts or
dead units of these types, I'd be interested as well.  One of my
brothers works for the RR, and he snagged these two from guys who were
just going to chuck them in the trash since they were broken.

Shoot me an email off-list if you have anything.

Thanks--

I understand this problem all too well.  This happened to my iPod (old
30GB model).  I solder almost every day, mostly surface mount (0402
sized parts usually).  I've done this for terrestrial systems and
space systems, I have favorite solder alloys for different types of
soldering.   I threw out my iPod when this happened to me.

I didn't toss it because the connector came off the solder pad on the
cable, I tossed it because it ripped the pad off the cable.  This was
just too much work to rework the cable with tiny gage wires when faced
with buying a brand new 80GB Xune for $200 (which I did).

If your solder pads are still on the ribbon cable (probably not), it
should be no problem to solder them back down.  Use a good quality
iron with a small tip (hint, don't even think about using anything
from RadioShack or anything like them).   I use a Metcal MX-500 sysetm
-you can pick em up cheap on eBay, $300 or so.    I recommend using a
63/37 eutectic alloy solder, hair thin, no rosin core with pretty much
any standard Kester flux (even the liquid stuff).  I can send you a
bunch if you need it.  Never use 60/40 (RadioShack) alloy for this
type of thing.

If you like, I'm very happy to do the soldering for you if you want to
send the part out to me.  Mail me off list and we'll exchange contact
info.
