Coreboot hacking: How to solder a PLCC socket on your board

[digitallyhere]

i tried some dumb ideas. i tinned the socket's pins then used hot air,only some pins stuck others were floating. increasing to 290C, melted socket surface. should have added solder to motherboard. used 60/40 solder. which type? lower temp?

so used iron. some pins didnt connect after some attempts, added alot of solder, worked, but damaged spring on the socket. next time i bend the tip of the pin downward so excess solder stays on the board. i used glue to keep chip up.

also needed a thinner tip.

sorry if this question is noob can you do this on loptop??

Nice video... Why not use the hot air to put the socket on? maybe easier?

Anyway, I tried downloading the music but all I could find was "Techno Twang Mix" not "Dreamy Twang Mix" - is this the same thing or different? Can you send me a copy of the one you used?

@Tda7000 Depending on the Material the Socket is made of, it might soften and warp, rendering it useless. Thats also the reason why some ( e.g. most micro USB ) Connectors have the Brown Kapton covering, protecting the Plastic insert from the heat of the Reflow soldering.

Thanx for being courageous and sharing your experience with us.

Hi can you tell me the tittle of the song!!!! many tks

you don't have to cut center of socket just use this heat gun to solder it

Thanks, that was very helpful.

Very well done tutorial video! I know how much time it takes to put together. Thanks for sharing! Looking forward to more of such tutorials! :)

Good to know. Thanks for sharing. Before watching this, I am very worried about how to do that. Right now, I feel a little bit confident. :)

It might be a good advice for the beginner to check for short circuits with a multimeter (between the immediate neighbors to soldered pins) once finished _before_ turning on the power.

NICE!

[arungordon1234]

did u use the original chip when you put it back in the socket or was it damaged by the heat gun? also, is there anyway i can remove the chip without a hot air gun? by cutting it carefully of the board maybe.

[uwehermann19]

Yes, all chips have survived the procedure so far.

If you would have used a little liquid flux that would have helped you in your soldering endeavors.

Very nice video. You almost make it look easy. Good luck with corebios testing!
