Slipped component

[dillingerdan]

OK, I have my friends PC, since I told him to get DDR PC3200, and he managed to get DDR2, and "install" it himself. He obviously missed the whole misalign notch and the fact it wasn't seated (seems to think it was), and now his PC doesn't respond at all when power pressed, opened the side, noted this:



It's legs are pressed against the resistors that you can see, to boot, so we have no life. Question is; salvageable? There is obviously some glue on the under side of the cap/resistor whichever it is, do you think replacing and a quick dab of solder will cure the board?

I give it 50/50. Easy enough to solder back as long as the tracks on the board haven't been damaged, just 2 legs and the tab. Don't worry about the glue, this will melt with the heat from soldering the tab and reattach. Not easy to see from the photo, I presume the pads the legs attach to are under the component. Honestly - worth a try the board is no good as it is. I don't see any solder on the legs so I don't think it was correctly attached in the first place.

I think you might be right, I don't thing this was properly soldered, maybe just touching the solder, as I can see a sort of slight indent into the top of the solder of the remaining solder point, and it is very slight... I've gotten it off the board now, thanks to the hairdryer. B) Only sort of localised heatsource I had. But its off, downside is It has the metal pad where the leg is supposed to solder to on the bottom of it, you can see it as the brown patch on the bottom of the cap/res.



Now, I have some solder, but now I am concerned as to whether it will make contact. I presume this is the memory power phase, so probably won't work without the cap at all?

Might just try it anyway, see if it works, if not nothing lost, it doesn't work right now anyway...

Be honest. It's not a friends, it's your isn't it?

 

[dillingerdan]

Fortunately it actually isn't. And thank god, cause I really can't afford to be replacing bits right now. Thats my Mushkin Redline RAM though.

There must have been some major heat involved for that to happen.

it looks pretty terminal i'm afraid. The copper bit on the back of the component is the contact pad from the PCB. It's very difficult to reattach this and then resolder the component. Usually if you lose a pad you have to give in an admit defeat because you can't solder the pad in place. You would need some conductive glue for the pad then some leaded solder (lower temp) for the component.
