Cpu socket replacement

[Vinster]

I've revived a few MB's by putting them in the oven at 175 Deg for 45min... I have a bad board at home, I wonder how easy it would be to pull off the socket if I put the Oven at 225 Deg... Melting point of solder... it should just pop off I'd think...

with the socket having datum tabs, I'd think just placing the new socket on the MB and putting it back in the oven would warm the solder and make the connections.

I tinker and having nothing to lose I'd try it... I couldn't think of a different process... solder points are between the PCB and socket... not sure how else a shop would do it other than having a fancier name for an oven.

trouble is you need to concentrate the heat on the cpu socket itself,too much heat and the pcb resin would melt ect,put it in the oven and you risk the whole pcb/component soldered joints to melt which you dont want to happen,if you can find a specialist that replaces damaged cpu sockets i think that would be the best way

As Wazza said if you heat the whole board, not only will the socket come off but so would everything else........... Now a heat gun from underneath it may do the trick. Not sure they get that hot though.

Tools & Hardware - Power Tools - Heat Guns - *at The Home Depot
Lowes and local hardware stores should have a few models to choose from.
The better heat guns have variable heat ranges from ~200^o to ~1100^o F.

I have one that is 1500watt, it'll get up to 300 Degree C... I'll give that a try.

Just thought id post details on how to get your cpu socket replaced if you have exhausted all possible channels with retailer and manufacturer,some manufacturers flat refuse to repair customer induced damage regarding cpu socket pins,however gigabyte i have to admit are pretty good regarding this,just recieved a direct replacement 1155 cpu socket but in the end it wasnt needed hence i thought id start this thread to help anyone else out in a similar situation,you can buy whole cpu sockets brand new from fleebay and depending on where you live in the world most accomplished pc repair or reballing firms can replace the socket for you at a cost,im only quoting from within the u.k,and the cost was £70 inc postage so bare that in mind with the cost of the board ect,i did haggle the price down to £50 so maybe you could try the same,if anyone does need the link for the repair firm i asked then pm me as i dont want to give free publicity

ill post some pics out of interest for anyone needing this help as i found it pretty difficult in sourcing/finding anyone willing to carry out the repair




above is the rear of the socket with all the tiny balls of solder attached




and here is the side where you insert the cpu,with no bent/broken pins

How did you pull the socket? Problem or broken pins missing! But with the hot air gun is not there a danger of inadvertently desolder SMD components also present? What technique did you use? Which speaker suitable metal for this company? Eventually I wanted to know if there is the possibility of finding a new socket to replant? Thanks for your help.

You mean something like this; solder station/hot air attachment (comes in different sizes): 42 x 42mm multi-chambered BGA Nozzle (A4343W)
I believe this enables reballing of cpu sockets?

[wazza300]

I didn't pull the socket its still attached to the board with broken pins,that pic above is of the spare new cpu socket ready to bo soldered onto the board

the prices I was quoted didn't make it worthwhile fixing so I never got round to having it fixed

you just need to google local pc/laptop repairs and email and ask them,you'll find some places that will be prepared to fix it

the MB connection on the replacement socket usually comes pre-tin'd, I was thinking of just putting the MB in the oven, and pulling the socket off once it started to float, then remove the MB from the oven, let it cool and clean the pad area up. Once cleanned, I'd place the socket back on the MB and place it back in the oven to let it re-seat on to the MB.

but with that many pins, it would be hard to tell until power up that all pins have in fact soldered correctly.

With the tip you posted, that may work, but I'd be worried about heating the Socket pins too much with that, I can't adjust the output temp on my gun. but if your is variable then it would be worth a shot.

My solder station does have variable heat and can be adjusted to the recommended heat level for the CPU Socket. The beauty of these 'shaped' attachments (nozzles) is that they only heat the area required; in a conventional domestic oven you risk frying the whole board as the temperature control on an ordinary baking/cooking oven may not be that precise! You would risk unintentionally over heating several other components!

Unfortunately my solder stations 'hot air' gun has a faulty fan and when I turn the control to alter the speed of the fan NOTHING HAPPENS, but it does make some loud buzzing noises sometimes?

The only trouble is: it's an ASUS board and I don't know where to get a socket from? (1155)
