Uwe, Great job on the "Soldering a socket on your board" Wiki page. I like it :-) What I do is take a piece of aluminum foil, fold it in half (for double the protection), and cut a rectangle out just the size of the chip. I place the piece of foil over the chip when heating it with my regular heat gun (about $20 US). The foil really helps to absorb the heat so nothing else except the chip heats up. I have one that I need to do, If I get time this weekend I will do it and take some picks if you want. Just let me know.
Yes, the page looks really good. Thanks a lot Uwe!

Some general electronics advice: Be careful with the heat. In general components are never rated for exposed to temperatures over 200 C for more than a few seconds as the temperature profiles in data sheets show. There are usually limits on safe temperature rise and fall times as well. LEDs are the most sensitive I've seen so far, but nothing likes 400 C very well.
I would not expect the chip to function well after heated to 370.
If I get time this weekend I will do it and take some picks if you want.
In any case I think that would be great!

Yes, heat on electronics is like a swear word.... bad :-( Maybe I'm lucky, but I have never fried a chip using the foil and heat gun method (and I have done alot). The trick is to blow the heat at an angle to the side of the chip at the solder joints going around and around in a circle. Never directly on top. If that makes sense.

Ok, will do.

Ok all done. http://www.coreboot.org/Soldering_a_socket_on_your_board
Although on the image pages it says: Error creating thumbnail: libgomp: Thread creation failed: Resource temporarily unavailable
???? It shows the little thumbnails just fine????
Uwe, If you don't like the way I layed it out feel free to change it.

Nice photos!

I think the photos are too high resolution for the limits set in the MediaWiki configuration. Maybe Stefan or someone can increase the limits somewhat?
(Or you could try uploading a new version of the files, at half the resolution or so, that might also do the trick.)

MediaWiki limits the amount of memory shell commands are allowed to consume. I increased that limit and everything should work fine now. Please let me know if you see more issues.

Thanks. If the images are too big and cause to much of a load on the server let me know and I would be glad to shrink them down.

I added a quick "Tips" section with a few things I have learned over the hardware hacking years, check it out :-)
Does anyone know if the Gigabyte MA790GP-UD4H would be ok for a coreboot install ? It has Dual BIOS that allows a backup copy to take over in case there is any problem flashing a revised version.
Would this avoid the need for soldering a socket onto the board ?

Sorry, that chipset is unsupported.

Hi,
I finally finished the accompanying video I made for this HOWTO, it's now uploaded on Youtube, archive.org, and blip.tv in Ogg Theory or FLV format. See
http://www.coreboot.org/Soldering_a_socket_on_your_board#Video
for the URLs.
The video is under CC-BY-SA 3.0 license, music is CC-NC 3.0, I took it from ccmixter.org.
Hope this is helpful for somebody.
I can't stress enough that my soldering skills are next to non-existant and that I _still_ managed to do this, and both the board and the chip survived. The procedure may sound scary, but it's really not that bad. Everybody can learn how to do this with a little bit of practicing.
Uwe.
