broken pin on motherboard

By qba98 ·
I have a strange situation with one of my personal computers. It seems that one of the tiny pins that connects to the floppy drive ribbon has broken on my motherboard. Is there a way to get my floppy drive working without purchasing a new motherboard? Any ideas would be helpful.

to guy with broken pin on motherboard

Is the pin actually broken? Or is it bent? If it's bent you can bend it back for it to still work. Maybe if its broken you can try to go without it :) hehe.

I/O Card

install i/o card with floppy controler,
and disable original in bios.
(you should find it in older computer or
buy it at local computer store)..

try liquid solder and piece of pin. get it right first time. than leave it alone

Grunt work :)

If you're handy with a soldering iron, you can replace the header pins with those from an old board. P.S.--Watch your iron temp, use good quality solder, and wear an anti-static wrist strap.

Yes! Thank You!

Doesn't anyone solder any more! Of all the parts on a mobo to need replaced, this is about the easiest. The traces usually aren't buried or anything on a floppy header. Once you learn to replace these, you can start changing voltages etc :) It's amazing how many boards will run better/faster with an occasional extra pin soldered on where the engineer intended one and somewhere along the lines it was removed.

Soldering pucker factor

by generalist In reply to Yes! Thank You!

When it comes to modifications like that, I know that the pucker factor of fouling up the board exceeds my ability.

Any suggestions on sources for improving such a skill? It would be nice to upgrade from knowing the basics to being able to do the delicate stuff. (My knowledge of the basics date back much too far to be useful...)

Soldering Training

by WorkinOnIt In reply to Soldering pucker factor

A lot of people laugh if you tell them that you went to soldering school, but I'll tell you what.....the training is well worth it.

If you want to get good quality training contact your nearest Air Force Bases Flight Training Detachment and ask if you can sit in on a High Reliability Soldering class, or if the intructor will give you some lessons. After attending one of their training classes, I can approach soldering with full confidence. It's a tough course, and beleive it or not, you may not pass it the first time through, I don't care how good you think you are.....

Sounds good...(Phase 2)

by generalist In reply to Soldering Training

Hmmmm. Fairchild AFB is not too far away from where I sit. I may have to consider such a course once I get my skills up to a decent level. (That's why this is Phase 2)

Come to think of it, I know a few ex-Air Force people who might be able to help. One of them was in an A+ and Network+ certification class I recently completed.

Well, I don't have a degree

by admin In reply to Soldering pucker factor

in soldering or anything, but seriously, to me it's all in the art of the flow. If you can make beautiful flowing old 18g wire connections, header pins aren't that much smaller. I've replaced a few surface mounts and that's tricky, but possible. Youhave to be careful on new boards, and although I used to solder in traces, I use a conductive ink pen now mostly.
Get an iron with a nice tight point and controllable or at least low heat. Get some old motherboards etc. that are dead and practice awhile. Use small diameter solder. If you soldered before you can do this. I use a magnifying glass and small vice as well as various alligator clips to hold stuff. Heat sinks are sometimes needed too, but the best is small diameter solder and just enough heat to make it flow beautifully and no more. I don't really know if that helps, generalist, but really, get some dead parts and practice a short while. It's fun and floppy headers really are not difficult. :)
