Spent most of my week replacing bad and or burnt headers on different boards and thought why not make a video and share the fun.



:eek:

I'll have to check this out tomorrow, won't buffer for some reason. Look forward to checking it out. I have a robotron/joust ps in my stargate that recently acted up, found pin 1 on 4p4/4j4 connector burned all the way through the side. +5v came back after a little cleaning, but needs to be replaced. Searching through previous threads I found many of your posts (and yellowdog too) to be very useful in regards to williams power supply repair.
 
It might be something on my end (Firefox on win7), but no video shows up for me :(

cheers

edit: Don't know why it was mis-behaving earlier... its working now!
One comment tho... that RS desoldering iron is not temperature controlled, so I'd make the point that you don't want to hold it on the pad for too long... it will keep pumping heat into
the board and will lift a pad or otherwise cause trouble. Other than that they work pretty well :)
I also like to leave the key pin in the connector and cut it flush as it gives one extra pin's worth of mechanical bonding to the board.

Its a straight Mp4 file...best bet would be to right-click and save it. You may also need Quicktime or Itunes if you don't have another Mp4 player app.

It seems to run really good in Quicktime

Very informative video. Makes it look easy to do.

Would love to see a video on the proper way to crimp molex pins. I struggle with that.

I will talk to my daughter when she gets home from school. We briefly discussed it when we made this video. I have to replace that connector on the heat sink anyway.
 
i had no problem watching it in FF; probably have the right Quicktime plug-in.

and it did make it look easy. i might have to go get one of those cheapy RS desoldering tools.

try clicking on compatability view under tools if you are running sys 7

nice video Dokert. i just wish you posted it years ago, then i wouldnt have had to self teach myself how to do it and taken 3 times as long !
 
10 minutes?

Holy cow, Dok-
shut the hell up and start soldering...

just saying

This long winded video is geared for those having problems changing burnt headers and those who have not changed a burnt header before.

Total time to change out the average burnt header is about 1 minute 30 seconds once you have become proficient at it.
 
Just bustin' ya.

On a more informative note, although I refused to watch your other 14 minute one, I flicked through enough of it to see that you have a crimper that will crimp down the insulation AND wire portion at the same time for the pin replacement.

Thanks for THAT!

At your level of expertise, going through at FF3 or FF4 would work just fine Brother.
 
Nice job, Dave. Wish I had time to do some of these videos, it looks like fun. :D

BTW, I loved the ceramic fuses on that ps board, 15 or 20 Amp?

Also, on the keyed pins, what I do is pull it up a little, clip it off and push it back down flush. That way you still get the pin to solder in for support and it doesn't stick up and get in the way when pushing the connector on it.

PS. Pay no attention to the grouch behind the curtain. Not all of us squandered our educational experience getting a EE degree, so having a set of "how to" videos aimed at beginners is a good resource for the community.

Nice video. Too add to this, I've had people ask me about the easy way to remove pins for keying locations without the occasional connector breakage.

One extra hint for making pin removal easier: You already have an excellent tool for removing pins for key locations -- that rat shack solder sucker.
I have one of them soldersuckers like you have in the video. These fit perfectly over the 0.156" header pins. Flip the solder sucker so hole is facing up (I have a vice that I put it in), insert the bottom side of the pin into the solder sucker hole, count to five to allow pin to heat up -- then pull it out with a pair of needle nose. Pin practically falls out and never breaks the header plastic.

I don't even look at the fuses anymore, I just chuck them into the ashtray that I put all of my trash in.

Good tips on those keying pins from both of you.

Very cool video, Dave! Never done one of those before but they don't seem nearly as scary now. :)

I'm curious as to what you were using for your magnifying glass / light as I'm finding it harder and harder to focus up close...

That's awesome, Dave!

How well does it work for you? I have a 20% off coupon so that would make it nice and affordable.

The magnifying lens on my little helping hands is a real PITA.
