Hacking Question Repair lost capacitor on mainboard?

[ErAzOr]

Hi,

while soldering the trinket board I slipped off with my soldering iron and lost one capacitor (see attachment).
Does anyone know which capacitor I should buy to fix this issue?

Wow
This is why I'm not doing any tiny soldering on my switch

It may work completley fine without it if its a filter cap, or you can try bridging the pads. Without a schematic or the cap that you lost theres no way to tell other than asking someone else to test the cap on their board

i say nay to use it without it and yay to asking somebody else to test theirs

From what i can find, thats a filter cap for VSVR, power supply from 3.3v to 5v it could run with out it. or VCC in filter cap. there is no data sheet on this chip as its an internal nintendo chip but one similar. stability well we dont know either way. The closest claimed chip is the "Rohm M92T36"

A note to anybody else attempting this mod, follow the trace from that capacitor and scrape the trace lightly and solder there instead. (Pretty much where the arrow is pointing)

Just as dangerous to an unskilled hand as soldering to the cap its self. To a skilled hand soldering to the cap is much easier then scraping the trace. Also since your waiting for cpu reset, the closets joint to the reset pin is going to be the most accurate.

Well I've chucked ample warning in every thread about the install I'm telling ya tiny solder guy is gonna make a killing. And with the SwitchME mod entering production soon I'm afraid we may see a lot more threads popping up!

 

[gameboy]

lmfao, you shouldve just paid tiny solder guy

Fair warning is good, and its intelligent this mod is not easy for the unskilled with out the right tools. I have to say, if you knocked that cap off, your iron was too hot. But thats just my opinion and it comes from years of experience in soldering and of course i'd like to say at this point after 14 years of doing this stuff as a day job I'm at least skilled. Don't have to call my self a "pro" but i can do the job, properly and well.

14 years of doing this stuff as a day job

The “10,000 hour rule” – enshrined in Gladwell’s bestselling 2008 book Outliers – holds that mastery in any field can be achieved with 10 years or 10,000 hours of practice.

If the stars align I will help you out - I need free time and an acquaintances fluke. but if its a filter cap, I probably cant help you - I cant understand the difference between a filter cap and a ferrite bead. filters act like fuses in my brain, like how you can revive an ipad pro by running wire in place of filters (I do have the appropriate ferrite beads now, but I still don't fully understand 'noise'")

I will remember your nick soon and stop calling you tiny solder guy by the way :-/

I don't mind, call me whatever you want! when I was living with my parents I thought my name was shithead and get wood (firewood, we lived in the country)

The guy went missing when people need him the most.

I thought I was right on time?

He's been here since tiny soldering came back up

Hi and thank you guys.

I uploaded some pictures of my damaged board:

I have measured both capacitors (lost and one besides) with a multimeter and both have a value of:
1,185 nF

 

[GhostlyCrowd]

1.1 nF is a standard value, and easily obtainable.
