Does anyone know of any game repair/soldering pros that would be able to swap the chips from a PS2 memory card into a donor with the same board revision?
I think this PCB is fubar but the chips look fine and I really want to recover my saves.

What the fuck did you do to it? Why is it burned all over the place?

A PS2 memory card IS the two chips you see, clearly there's not much other circuitry. It's going to be way easier to replace a small resistor or whatever else could have failed, than to unsolder one of these chips without damaging it. 99% of the problems with PS2 memory cards are just the contacts being worn out. You can try to glue some new copper pads (with some conductive glue of course) or something

It's corrosion, and I don't know I didn't take care of my shit as a kid then it went through multiple moves in a box somewhere.

Clean the contacts first with isopropyl alcohol to test it out, you're gonna have to scrub it for a while but it may still work. Otherwise hot airing off the ram chip and putting it on another board may get it going. Hot air would be trivial for that. Only some of the vias look bad but that doesn't necessarily mean they are totally dead.

>>11830190
I thought memory chips are very sensitive to temperature?

>>11830242
then heat the underside of the pcb instead of the chip so it just melts the solder and releases the ram chip

>>11830251
Getting the entire PCB hot enough to transfer the required heat to its other side is a horrible idea, anon

>>11830264
not really when it's all corroded to shit, apply flux to the area you want to collect heat and u win the solder championships

trust me anon i do this professionally and I'm also a master gamer and soldering rewards all kinds of gamer thought

>>11830087 (OP)
Clean it with IPA using a tooth brush, use anti corrosion liquid on the connection, then once clean put it on electric oven at 200 degrees for some seconds.
Done you refluxed the memory card.

>>11830276
I used alcohol on the contacts a while ago and it didn't help but I guess I'll try again tomorrow.
>anti corrosion liquid
Vinegar?

>>11830276
>put it on electric oven at 200 degrees for some seconds.

lol, the horrible advice this board gives still astounds me. The entire board is 2 chips and 5-6 discrete components. You can manually reflow that with an iron in less than a minute, there's no reason to go holocaust on the entire thing.

>>11830354
contact spray or even WD40 will work. I prefer WD40 because the contact spray I use makes the PCB lacquer look all wobbly. Once you cleaned it, optimally you'd want to check if all the traces still make contact, especially the ones around the vias that look corroded. If any of the vias are broken, you just might be able to fix it by filling them with solder. If that doesn't work, you could potentially put thin single strand cables through the vias as bodge wires.

But it's not impossible that your initial assessment was correct and the PCB is too corroded. If that's the case you can use hot air to remove the memory chip and replace it to a donor PCB. If you don't want to use hot air, it's possible to use low-melting point solder like Chip Quick to remove the chip, but that gunk is a pain in the ass to clean off.

Why are you even bothering with this, mind you? Aren't PS2 memory cards, like, 10 bux total?

>>11830367
It has some childhood save files on it that are irreplaceable. I can't do soldering or especially chip swapping myself because shakyhands, I'm looking for recommendations on people who have pulled off successful microsoldering jobs like it

>>11830392
Ask around at psxdev, they know their way around playstation memory cards more, maybe someone there will be able to help. I'd try to dump the NAND chip first, just in case, then move it to another PCB. That way if it fries, you still have the data backed up (for use in emulators, or burning it into another memory card). But I don't have a NAND reader so I couldn't help you.

>>11830367
I bet you know more about wearing skirts then about electronics.
The advice is valid as long you don't go full retard like most here will go (you).
Irons release steam even if they look empty retard which causes more damage (unless you have a 1980 iron).
>>11830354
>>11830392
There are anti corrosive liquids that will remove rust and mold along other impurities.
If you can't find mix one part of vinegar with one part of salt and rub it in the contacts then finish cleaning it with IPA.
If you have bad pulse or can't solder putting it on an electric oven is valid (method used by most technicians on PC shops that do reflux).

>game repair/soldering pros
its a 5 minute job any retard ould do just take it to some phone/laptop repair shop if youre a solderlet

>>11831174
if the board can't be fixed swapping chips is definitely not a 5 minute job

>>11831179
yes swapping chips to another board is a 5 minute job its not difficult

>>11830087 (OP)
i dont know why you dont just transfer them to usb
you said Playstation 2
use USB

Sometimes you just need to let those old save files go.

>>11830087 (OP)
I can do it anon, if you are U.S. based you can ship it to me, and I will perform this service for you, for a fee. My discord is: gigachad1588.

>>11833434
Because the card physically has broken traces, it will not connect to my PS2. The chips need to be swapped onto a working board.
>>11833513
no

>>11833732
Oh
Get a trace patch kit. Nothing there actually matters and no one is going to just give you several hundred dollars worth of SMT reflow/reworking equipment for your one (1) child’s toy accessory.
This isn’t a game anymore. Fix it or don’t.

>>11830087 (OP)
Oh you fucking punk ass bitch
90% isopropyl alcohol and some cloth for glasses
You fucking idiot I cannot believe you didn’t clean the contacts

>>11833798
I did you dumbfuck, they're that badly corroded.
>>11833796
The hell are you talking about, I would be paying somebody with the equipment to fix it.
>child's toy
Where do you think you are?

>>11833732
>>11833891
Nigger, just repair the traces... Use a bunch thin solid core wires. Do you really think swapping the chip without cooking the memory contents is going to be easy?

>>11833732
You have no idea what you're doing. Kiss those save files goodbye

>>11830087 (OP)
step 1: get another board
step 2: cut off the bottom of both boards with safety scissors
step 3: duct tape the bottom of the good one to the bad one
step 4: blow on it, then insert into console and retrieve your maximo save with 3 hours of playtime
you can thank me later

>>11834259
Are you people fucking retards or something? What part of "I'm looking for someone that can do this" can you not get through your thick fucking skull?
I can't solder let alone something tiny like this, I am LOOKING for someone that CAN in return for payment.
The flash and MagicGate chips are not visibly damaged, if they were both carefully swapped onto a memory card board with the same design it would work.
What the fuck happened to this board, did most of the people with IQs above room temperature leave after the incident in April?

You're searching for an answer in the wrong place, bro. 4chan is where you come to either A) look for knowledge by offering your own stupidity as a sacrifice for the pleasure of others who might drip feed you information interspersed with severe beratement, or B) flex your own intelligence and soak up the loosh from people stupider than you by beating them down and forcing them to accept your viewpoint. Positing a question on 4chan and hoping for friendly replies is foolish; double foolish if your response to any meanie words is "are you retarded??!!!", that's just going to get the hyenas worked up even more and give you even less of what you want. I mean this in complete sincerity: go back to redd*t and make a similar post there within the appropriate sub. You will undoubtedly find a horde of obese nice guys to service your needs. If you absolutely refuse to do so, then stop posting, wait 2 months and return, except this time post a green text where you call yourself retarded multiple times and say plz no bully, then put cash on the table, and you might get what you want. Otherwise, you're wasting your time.

>>11834567
True, but /vr/ used to be a decent place by 4chan standards.

>>11834568
Compared to the rest of the site, /vr/ is a very decent place. You're just swimming with sharks and expecting not to get bitten. There are many dudes on here that have a scope of knowledge greater than any other place you'll find on the net, but that kind of autism is almost always going to be accompanied by a superiority complex, and if you don't appeal to that complex, then you aren't going to be granted the esoteric knowledge they hold.

I think you would be far better off first attempting to see if you can get that PCB working at least long enough just to get the save files off of it rather than instantly going for the nuclear option of swapping the chips to another board. Maybe soldering wires to the pins and connecting those to some kind of reader considering your main goal is to recover your saves, not specifically to get the card working again.

>>11834551
>>11830087 (OP)
i can do it but its going to be a pain in my ass &
i cannot\will not 100% guarantee a safe recovery
there is a high chance of failure as even if you get the chips off the board without frying them you still have to resolder them back into another board

floweranon88 at gmail
best of luck buddy

what i would do is CAREFULLY clean the fuck out of it, add solder to the connector edge and smoothen it and try to manually move\transfer your data to a NEW card on the system before attempting chip removal\transfer


just my two cents

>>11834809
if you dont want frogposters to do it via the us mail and paypal then i would check ebay for "pcb repair" shitposts and inquire with them
atleast ebay would refund your (trivial) money

but losing the saves is probably more important to you than whatever $100 the repair guy is gonna charge ya

>>11830087 (OP)
Put it in the microwave for 10 minutes at 50% power

>>11834551
nypa you fucking delusional newfaggot
My billable hours are more than you can make at all ever

>>11834568
Go away.

At no point does hot air fry the contents of an IC
You can melt the epoxy or filler it’s housed in and it will still work
You are not an SMT repair tech
You are a nazi trying to get personal information from a very obviously underaged poster
You’re probably a registered sex offender

>>11835037
>At no point does hot air fry the contents of an IC
This is not true, I've unfortunately done it before. Some ICs are sadly very easily damagable. A memory chip would be more resistant to damage of course.

OP, where are you even located, if it is within the EU and you can send confirmed working replacement card, I can swap the ICs.

Not only are you brand fucking new you just want to stalk this guy

that isn't a nazi, that's a deranged redditor tranny looking for friends, a pedophile, a nog trying to make an easy buck, or a glowie who's trying to narrow down OP's location after he saw him say something bad about jews on /pol/. the brand of wolf in sheep's clothing on display here is overtly liberal in nature.

Stop posting

>>11833994
nta but itd be way faster to just swap the chips you dont even need hot air either you just solder wire all the way along the legs around the chips cover it in solder heat it then lift it off literally a 5 minute job kek

>>11834551
nigger just order another memory card with the same pcb and go to literally any laptop/phone repair shop near you they will do it

>>11835037
What the fuck? Kek

I don't see why people are shitting on OP. Not everybody can do everything, nor does everybody want to spend the time to learn every skill they could possibly need, not to mention that if he's new to soldering, experimenting on something he actually cares about isn't the best idea. And yeah, a hot air station would probably the best way to remove the chip, and no, you aren't going to damage the chip unless you just keep blasting it with the hottest air possible for an extended period.
That aside, I would suggest using some computer paper with alcohol to REALLY try to scrub off more of that corrosion. And after that, some Weimann's stove top cleaner, and if that doesn't work, Brasso. Yes, I know Brasso is bad, but given the state of that board, and if nothing else works, then you might as well give it a shot.

>>11839487
>I don't see why people are shitting on OP
Like 10 different anons already gave him the advice to clean the contacts and he keeps ignoring it. He doesn't know what he's doing but somehow still convinced himself, that the correct solution is chip swapping. We are right to laugh at him
