What's this mobo component I just broke ??

post #1 of 13
Thread Starter 
Ok so to make a long story short, I just got a replacement for a faulty board and installing the M.2 drive, my screwdriver slipped and hit the pcie bracket. After careful inspection, I found out that one of the small components under the pcie slot was hanging sideways, probably by a portion of its remaining solder.




When brushing my finger on the component, I can rotate it sideways, or push it back on the mobo like the other components besides it like nothing happened. However, it's very easy to make it rotate. I ended up putting a piece of tape on the row of components but I'm having my doubts as to if I should go on with the build and turn the power on.

Can anyone let me know what is that component and if there is reasonable grounds to RMA this board once again. Can I just go on without any problems ?

Regards,

Looks like the Flux Capacitor.

It'll either be a small surface mount capacitor, or a termination resistor (which looking at it is more likely). To me it looks like its on one of the PCI-E channels, so it'll need resoldered, otherwise the channel will be dead. If you don't plan on using that particular slot, just whip it off, and all should be fine. where it is, looks like the slot would work fine in X8 mode anyway.

Interesting option of using the slot as X8 only. Is that an option in the bios ?


Can I just try and solder it back on to sit in properly ?

Can I bring my soldering iron to heat the capacitor and liquify the cracked solder and try and reseat the capacitor ? Can these resist the heat of a direct contact with a soldering iron ? I'd rather not try and add more solder and take the chance to drop a big gulp on other points. I'd also rather not try to touch the solder itself and take the chance of heating the mobo's plastic substrate.

Are these capacitors attached by two soldering points on both vertical ends ?

Your going to have to be pretty gosh darn precise to solder that back on. I would honestly RMA it again and say it doesn't work. They probably won't know the difference and send you a new board.

yup, you can just resolder it back on. You'll need a fine tip soldering iron, and you'll need tweezers to hold the components in place. It's a fiddly job, but can be done. If you just try it with the soldering iron, it'll probably melt the solder both ends and the component will bugger off. smile.gif so use tweezers, it'll help sink some of the heat too, and not damage the component.

Edit - oh and as for the X8 option - the board would probably default to that once it realised it had a dead lane.

I would RMA the board if possible unless you're sure of yourself with the soldering iron.. No sense doing repairs on a board in warranty, sounds like it came with weak or broken solder joints to begin with.

If you leave it as it is ....you have warranty, and can...at any point to send it back for RMA pointing out that it only works at 8x and you have a missing part...
If you solder it... the second the solder iron touches the MB...bye bye warranty....

You decide...but a component flying just by dropping a screwdriver onto it...while doing the ssd screw...doesn't add up....poor QC from the MB or you dropped the screwdriver from like...1 meter or more rolleyes.gif

Yea, I've figured that this was a precision job. I'll try to use it as is. If it gives me too much artifacting or crashes, I'll try disabling X16 for that lane. If the option is unavailable, I'll try and solder with extreme care. They won't notice.

Thanks for the tip, I'll try soldering as a last resort and with very little heat at a time until the capacitor stands on its own.

It probably did. I know it's covered, but this is my second RMA (first time the X370 had a defective DIMM slot) and another two weeks of not being able to transition to this system for workflow (video processing) is not an option. As stated above, I'll be gentle and it will be undetectable.

It probably had a weak solder to begin with, you're right. I'll solder as a last resort before RMA and with extreme care. If they notice it, they are inspecting 100% of the area of returned components with microscopes.
