Dear all,
While i was changing cooling fans, i accidentally drop screwdriver onto motherboard, and broke two tiny capacitors.
Now, ports 9-16 not working, those capacitors is located above second switch chip from the left side.
Picture attached.
Can somebody help ?! I just need values of those two capacitors.
It is really tiny 
Thanks !
Best regards !
I’d take a stab and say it is more than likely bypass / filter capacitors for the chip.
As a unwritten ‘standard’ - try 0.1uF, maybe 6.3V (you should be able to get a voltage reading there to rate the caps appropriately for voltage levels).
Hello,
Maybe MikroTik can help?
Its not a big deal for them to reveal values for those capacitors.
Anyone?!
Please !
Those would definitely be 0.1uF. Looks like standard 0201 package so likely a 10V X5R variety.
Thanks to everybody, its working now !!!
It was nightmare to solder so tiny capacitors, but i made it !
Best regards !
Can you confirm exactly what you did so others in the same situation might know?
No problem, that caps are indeed 0.1uF ( 100 nF ) SMD 0201 type.
I ordered a bunch of these from Ali, they are cheap.
Main problem was dimensions of those caps.
They are 0.8x0.4 mm and without microscope it is impossible to solder it back.
I have destroyed a dosen od those caps, until i made it to solder properly.
The rest od the board, around elements, you MUST protect with kapton tape, to avoid risk of desolder something else near.
I have hot air gun but i didnt have low temp tin solder flux, and normal flux without tin, didnt work. Have tried. Caps got blown away even with lowest fan setting.
Finally, i did it very carefully with Weller Soldering Station with 0.4mm tip.
And most important thing, you must be calm, have steady hand and microscope.
Conclusion: Maybe it would be easier with tin solder flux with low melt temp, about 180C, dont know.
Best regards !
