Switch OLED teardown V1/V2

[firefly360]

Anyone in the US have any extra, or info on the best place to order?

Hello mattyv,
I have some dat0 adapter left, made by pcbway. They are now in China:
1-3 : 15$ USD each piece
4-8: 12$ USD each
9-10: 10$ USD each

International shipment with tracking : 6$ USD

Please PM if interested

So I've picked up most of the items and watched the install video a few times. I'm usually pretty good at picking up new skills and I've soldered a bunch of times but nothing prepared me for how TINY everything is! This is going to be a tough install....

Just waiting on my Align Me Board and Solder Mask....

 

[kerelenko]

Yeah a microscope is recommended. You should have seen the balls on the emmc chip they look like tiny pin holes.

 

[Mulanzo]

Bad news - managed to solder all the wires to the motherboard and managed to solder most of the wires to the Lite Modchip but the soldering tip broke mid soldering the CPU 2 wire to the leg of the chip on the Modchip and I ended up bridging 3 legs and knocking off a resister somewhere. DAMN! Gotta buy a new modchip now

wow, everything looks so big in the video.
What kind of microscope do you recommend.
This will probably be the only micro solder that i do

aww man you were almost finished as well, just bad luck at the end of the install

I'm pretty happy with this from Amazon (Germany)

I cut the 2 silver clams, to keep the motherboard plain. The stand is from my point of view a must to get clear picture.

Thanks man, i was earlier thinking of cheaping out and getting this:

But will opt for this, more expensive but will be easier to work with

I have a similar one and admittedly it works very well but because it’s operating as a monocle you don’t have any depth perception so I found it tricky to work under it.

Yeah it was all going pretty smoothly and the tip of the soldering iron snapped off and I ruined the chip. After this I don’t ever plan to do microsoldering again.

Also, I still don’t have my Align Me chip but I did everything else. Guess I have to wait for another modchip to arrive as well so I have to microsolder atleast once more

Can you salvage the chip?
Was it an SX or hwfly?

What is the Align Me Board?

How did you scrape away that one solder point after you cut the metal frame? (See pics below)
I dont have a grinder pen

This is my cost for the materials for soldering:
Dont think i'll do any more soldering after this as well.

no need grider pen. just use sharp like knive

 

[gregor4711]

please buy with stand. Since the magnification is high (400 -1000 x), you are not able to hold it still. But with stand there are crystal clear pics.

Pretty sure the chip is Fubar at this point. I'm not skilled enough to remove the solder bridging the three legs and I have no idea where the SMD popped off from.

For the grinding spot, I used a Dremel with a tiny grinder tip on the lowest speed setting and it worked fine. The solder point is TINY. Definitely need the Solder Mask on that point afterwards.

Align Me board is the little Dat0 BGA adaptor PCB that gregor4711 has a few extra of. Highly recommend contacting that guy. Super responsive and quick and his price is super reasonable compared to buying 100 from PCBway.

I'm a little bummed to have ruined my Modchip but I've already started so there's no turning back!! Just have to wait for another to arrive. My bill of materials is rapidly increasing however lol

Aww, if the solder tip fell onto of the chip it may have been fine, but if fell on the corner!
This is how the chip suppose to look, you could try solder wick to mop up the solder from the legs, the only problem will be locating the resister.

I ordered a Dat0 adaptor from gregor earlier as well!

Hey!
I'm sorry you could not finish it but the chip is not ruined yet
you could save it. it's just a matter of removing he bridges and repositioning the capacitor (that one knocked off is a capacitor).

OOOH! I will try to salvage it. Doesn't hurt to try. Here's a closer look at the damage:

Blue Square - Where the tip landed. The corner of the black chip is a little discoloured. Is this a problem?
Red Square - Looks like the leg bent sideways. Is it a problem to straighten once the bridge is removed with Solder Wick?
Yellow Square - Looks like a leg is missing? Or bent into the solder glob....not sure this is fixable....
Green Square - Is this where the capacitor goes? Does the orientation matter? If the capacitor has prolonged exposure to the tip, would that ruin it? I had to scrape the capacitor off the broken tip of the soldering iron.

Thanks for the help!

 

[mvmiranda]

OOOh…. How does one remove the solder bridge. And where does that capacitor go?

You can use a solder pump, solder wick (also called solder braid) or even your soldering iron.
Use a good flux, put a small amount of solder in the tip, clean it off (you don't want to apply more solder, just make the tip ready to "suck" the solder excess) and quickly touch the bridged areas and pull the tip towards the "end" of the pins, almost as if you're sweeping the iron. DO it quickly, do not sit the iron to "melt" the tin.
Touch, Sweep and remove. In one movement.
The flux will help evenly spread the heat and the melted tin will be "sucked" by the iron tip. The surface tension of the melted tin will "pull" (or suck) the bridges out of the board to the iron tip.

Sounds too much but it's actually quite easy!

As for the capacitor, @grubgrub already posted a picture of what the areas should look like. It's like this:

Good luck!

Dont think i can pm you yet. Where are you getting these from?

I ordered them on pcbway for my personal use.
Since the minimal price is 109$ with shipment, I ordered a few many. It's currently stored in a warehouse in China and ready for shipment.
