ECS K7SOM+ On-board Processor burned

[stng]

Recently got myself a ECS K7SOM+ after checking and found that
the processor burned and causing short on VRM circuit ..

Thinking to removed the burned processor and fixed with
ZIF socket ..anyone can tell me how to do it ?

Re: ECS K7SOM+ On-board Processor burned

Maybe using a heatgun to remove the bad CPU, then get a ZIF socket (again using a heatgun on a dead board). The most time consuming part would be cleaning all the holes and then soldering the socket in.

Find a used socketed board and recap it...

Here it is in a nutshell...

PcChips M810D / ECS K7SOM
PcChips M810D 5.2A / ECS K7SOM+ V5.2A Thoroughbred XP 2400+
PcChips M810D 7.5A / ECS K7SOM+ 7.5A Thoroughbred XP 2600+ (266 version)

PcChips M810D 7.5C / K7SOM+ 7.5C CANNOT upgrade, embedded cpu.

NOTE: PCChips M810D / ECS K7SOM+ : Remove C453 for XP support.

yup,u r write ..but the problem is i don't have access to heatgun..possible
to use sucker to removed one by one of the pin ?

There's nothing wrong with the cap i guess..

Re: ECS K7SOM+ On-board Processor burned

I think I see where MD is going with this.
The frustration and failure factor with removing a CPU and inserting a socket is way more than finding a board like yours with a socket and putting in all good capacitors
for stability.

Anyway gonna give it a try and update the status
later ..if it worked out..

Exactly... there are MILLIONS of those boards around. The ones with the embedded CPU are a real pain...

But I also understand the pride in the ability to repair something with your own hands and skills...

I can say "good luck" with your project!

Yup, if you manage to successfully do it, your name will be included to the hall of fame /jk

It is pretty much impossible if you don't have some proper equipment.

not... yet. OST and GLuxon <-

Thank you Yanz, This was the xray view I was searching for a year ago.
It helps to explain how thru hole clean out is a delicate procedure and how unseen things can be wrong with a ground plain.
You are the est.

nothing really, i linked the link that already linked here, somewhere... you're welcome btw

Re: ECS K7SOM+ On-board Processor burned

Have the burned processor removed by slowly knocked the processor in pieces then
removed the pin one by one ..now is trying to fixed the zif socket ..

Re: ECS K7SOM+ On-board Processor burned

Removal the on board CPU with a hot air gun. You may get some surprising from the dead of these kind of mothboards.

Re: ECS K7SOM+ On-board Processor burned

Ok done with the ZIF socket ..when fired up,it just won't POST but the fan is spinning
so guys any idea ?

Re: ECS K7SOM+ On-board Processor burned

Is VCore OK? Are all solder joints good and no broken traces?

Re: ECS K7SOM+ On-board Processor burned

it likely has a vrm problem.
look for shorted mosfets.
bad news...it may kill every cpu you have tried!

Done with the ZIF socket?
Please back up a bit. How in the name of all that has pins on it did you get a line up and set down of the socket.
What was your method? heat source?
I read up on the manufacturing process for these, and they use an electron microscope and xrays to check the joints.
Please share your technique.

Re: ECS K7SOM+ On-board Processor burned

I don't think it's hard to solder. If the holes are clean (cleaning is probably the biggest problem) and the socket pins straight (not a problem when removed from another board using heatgun), you just put it in and solder the pins one-by-one.

Re: ECS K7SOM+ On-board Processor burned

Sorry,
Guess I better shut up.
The board I thought about doing this to was surface mount proc and socket, so I was thinking small pads, heat and compression.

Re: ECS K7SOM+ On-board Processor burned

Many P4 boards have SMD socket - that's really a problem.
