Hi I'm trying to remove a eeprom but for some reason the solder will not melt iv tried it at 400c with hot air and will not melt any help will be grate
@@davidflanagan4420
Plenty of flux...
Mix some lead solder, that will help reduce the melting point...
Job done!
👍👍👍👍
@@LMAutoRepairs thank you so just add some solder and flux with iron then more flux and hot air and hopefully it will work 😃
Finally, i was waiting for this video, yes there are more videos of chip welding but they don't explain anything good job, greetings from Chile

I had to swop the eprom over onto another set of speedo clocks on my vectra c, so It would diaplay the correct milage. Worked a treat considering it was my first time desoldering and re-soldering a eprom. Great video as always.

Hi thanks for sharing such a informative and practical demonstration on how to desolder and solder
I was wondering if you you can make video on how to open a ecu cover and also how to remove the circuit board off the back cover like the board you used in in this video Many again
Hi
I think I never recorded that...
I will plan it for the next time I have to open one...

Add flux on pads after removing parts and melt the solder on them with heat gun before replace components!
thanks a lot for this video i asked you reference of flux and liquid cleaning to
Hi
I use flux AMTECH NC-559-ASM-UV
To clean, alcool... Isopropyl Alcohol

Soldering, I use a temperature controlled soldering station...
The rest, look at the answer on the fixed top comment...
Thank you for watching and for your comment!
bro. bro. please help. where do you get your diagrams to know where to solder?
I need an eeprom replaced on my pcm. Where are you located?
Another great video. Thanks
I wonder if you are going to give us a video on how you separate Peugeot bsi spring loaded plugs. I am dying to see such video, thanks once more.

Thank you. You just earned another subscriber :). Can you make a short video to solder the eeprom with soldering paste with hot gun. I just need to make sure the right temp and which paste is the best, because I just keep burning the eeprom legs :). I bought some chip electronic stuff, just to practice with eeprom soldering.
At the first try, I did an amazing soldering, it was the ECM of 2001 Lexus RX300, but I don't remember which paste I choose T3 or T5 and what temp I choose. Since then, I keep burning eeproms.
Anyway,
Thank you
Hi
I will plan that in... the hot air gun temp varies... it is also important the distance from the chip... if that makes sense...
Thank you for watching, for subscribing and for your comment!
Great video 💪😃 did you using same flux for soldering and desoldering?
Yes... I use the same...
👍👍👍
Thank you for sharing this video with us,but I would like to ask,Does the direction of the chip matter when you remove it,and replace it with another one,or use the same one?
Hi
Yes it does!!!!
In this video I was focusing on how to solder and desolder...
On some other videos, I mention that, and how to mark the chip direction....
Thank you for watching, and for pointing it out!!!
Hey there , thank you very much for your amazing Videos :)
Please make a detailed Video with carprog reading writing of eeprom 95160 (maybe Airbag eeprom of a Peugeot 207 or another car )
Where you get your carprog ? Need it to be repaired ?

Thanks sir 👍🏻👍🏻
Thank you for watching!
Thanks so mach
No worries!
Thank you for watching and for your comment!
I noticed on first technique you applied the flux as a glue to hold epprom like chip in place before heating the legs up again. I am reading you said you need to clean flux off so you get a good read. I am going to attempt to replace the epprom chip on my TV and want to know if first technique will work. How do you clean it if you use it as glue?
I don't use it as a glue... that is just the flux consistency... you can clean using alcohol...
Thank you for watching and for your comment!
Great video. Do you do immo off ?
Very rarely...
I always aim to fix the issue rather than do that...
👍👍👍
Does the aluminum tape not short out anything?
What do you use to clean the circuit board?
Short?
The board is not powered...
And once the work done, the tape is removed...
I use isopropyl alcohol...
👍👍👍
Hi Luis, what brand of microscope are you using in this video? I'm trying to figure out which one to buy for detailed soldering jobs like the one you very kindly (and professionally!) showed. And it looked like the one you are using is giving pretty good results :)
Hi
The one I use is nothing special... is good to inspection, to actually solder and watch at the same time you might want something different...
Nut the one I use, you can easily find it on eBay... my one is the 500x version.
Hope that helps.
Thank you for watching!
@@LMAutoRepairs is it the one that comes with the screen, or the USB type, that looks like a bullet shape?

Interesting! Lol
Na boa...
Add flux before remove components!
boa noite amigo u sr tem mapiamento do modulo audi a 4 2.8 v6 ano 95
I'm curious how you desoldered the cpu chip from that board... Doesn't the solder on one side of the chip re-harden as your going around the chip with the soldering iron when there are that many pins?
Yes... you need to be quick...
I have another video on that coming soon...
Stay tuned...
Thank you for watching and for your comment!
If you ever run out of the Aluminium tape, google Kapton tape - it is made for protecting heat sensitive devices / plastics etc. The tape also isn't conductive like the aluminium tape.
I actually have some of that...😉
Thank you for watching and for your comment!
👍👍👍
Great Video mate, im just looking at going into eeprom work, why do you clean the chip? what does that do? and what is the use of the flux?
also what is the cleaner you used?
The flux is to remove oxidized metal from the surface of the metal... just Google it...
To clean, I use isopropyl alcohol...
You need to clean, specially if you plan to read it... otherwise the flux prevents a good electric contact...
Thank you for watching and for your comment!
How easy or difficult is it desoldering and soldering a msop8 which is alot smaller? I need to work on one soon but unsure whether to tackle it....
Thanks
Irfan Khalifa
Hi
Same principle... more patient and careful...
It will take longer...
👍👍👍👍👍
Thank you for watching!
Hi do you determine what chip is faulty and how do you know which chip operates a particular component. Thanks
Hi
Eeprom always stores immo and configuration data...
So, that's an easy one...
The other ones comes with experience an research... if that makes sense...
Thank you for watching and for your comment!
Very good video, I need your help with the diagram of the ecu toyota vitz rs 2004, it will be that you have some data that you give me.
Hi
All the stuff I have for Toyota, which is not much by the way... is at a distance of a Google search...😉
Can this be done to "clone" a replacement instrument cluster with immobilizer and milage data so the car will start?
Yes...
Providing you replace the correct chips...
Thank you for watching and for your comment!
Can t help myself to ask me every time what are that two old crt tv for ,I have also two and planned to get rid of them long time ago ,but still keep it ..
LoL
One is indeed an old CRT TV, the flat screen one, is actually one of my computers monitor, which I don't plan to get rid of... at least for now... lol
Thank you for watching and for your comment!
I always wanted to know how to change them chips properly..tell me this can them chips go anyway around..awesome video by the way
Conor Cousins they dont go anyway around , there is always a mark position pin 1 side on chip but not always marked on the pcb so mabe you want to make a sign on pcb when desolder it.
Robermon YT
Absolutely correct!
I mention that on other videos...
👍👍
You have to mention that is much better to desold and sold by hot air when you have to test a lot with the chip, if you use solder iron more times you risk to damage traces because they are very thin.
Robermon YT
I don't even do that... when I predict I need to desolder and solder many timed for example, an eeprom, I just solder an adapter... 😋
But yes, you are correct... this was only a brief explanation on how to to do it... that's all...👍👍👍👍
Nice
Thanks!
👍👍👍
thanks
😊
👍👍👍
What temperature is your heatgun to melt the solder?One i bought was a 500 degrees centigrade one,eeprom won't budge????
Probably lead free solder, but, at that temperature should do...
Maybe that 500 reading is incorrect...
Use some lead solder to mix with the lead free solder using the soldering iron, then should easily come of...
👍👍👍
@@LMAutoRepairs Thanks,unfortunately 2 of the eeprom pads have dislodged on the pcb due to my frustration!! :-/Luckily it was a module i bought to practice key programming etc on.
Carry on practicing, as I said, use lead solder to mix with the lead free, that helps a lot...
Or buy some low temp solder for those situations...
👍👍👍
Hiii
Where did you learn all these things on vehicles?
Self taught...😊

I am trying to find where the immobilizer chip is located on the motherboard of a 2007 Toyota Corolla matrix-having a very hard time. Was wondering if you know where I could find the information?
On which module?
Thank you for watching!
On the main engine computer for a 2007 matrix.
@@nicholasrolla2937
Hi
Either in the external eprom, or in the eprom of the MCU.
Some cars can have it on the flash of the MCU as well... you need to search for that specific ecu...
Hi man! I was trying to remove eeprom from toyotas immobilizer on 300 degree, same air speed, but it doesn't want to come off. What can be a problem???
Use flux to help out... if the pcb is lead free, with the soldering iron to mix some lead solder...
Another thing is, if your hot air gun temp is not correct, or you are keeping it too far from the chip...
Hope that helps...
Thank you for watching!
Thank you!!!
I'm right-handed and now I'm left-handed due to a stroke so I know what you mean lol

I followed your video on how to replace eeprom on my 2005 206. I took the eeprom from the original burnt out bsi and put it on another bsi( second hand). But now i have an immobilizer fault show up. What can I do? (Great videos thanks).
Which chip have you swapped?
What was written on it?
Thank you for watching and for your comment!
@@LMAutoRepairs Hey, thanks for getting back to me. The chip I replaced was the 8 pin right on the back. Number 951603 9534w.
I really appreciate your videos because getting anything done here in Australia is super expensive and takes forever, so you have been a lifesaver.

OK...
The software versions, are they the same, on the old one and on the replacement one?
If the software versions are different, that might not work...
@@LMAutoRepairs I assumed they would be the same. I ordered Lexia 3; so when that arrives I will delve a little deeper. Thanks for the hint.

hello! i have a problem... when i try to read at 25010 eeprom, program will read only zeros what that means and what means if it shows only F:s.?
Thanks for help!
Hi
That's either a bad reading, due to poor connections etc... or the chip is blank...
Thank you for watching!
@@LMAutoRepairs i dont have yet any adapters so i used a4 adapter (from carprog set) and solder directly to eeprom. I have checked multiple times and they are correcly.
why i cant write anything to eeprom if its blank?
Im trying to put immo emulator to ford puma 1998 so i wonder that if i order new one if i cant write to this, can i just put those values over there what julie's manual has ? (carlabimmo.com/julie-manual)
sorry for the effort..
@@jusgaa
If you have everything connected correctly, and the programmer you are using is compatible with that eeprom, you should be able to write whatever... unless there is some sort of WP on that chip... you need to research....
@@LMAutoRepairs i can now read it but cant write it, have you heard about Block Write Protect Bits? if im correct you need to program the reader device to ''unlock'' to enable write. got the info from datasheet. have you done this before? theres not more info out there about that... (I think I bit off more than I could chew)
@@jusgaa
On some chips yes...
Video was good but you have applied heat on pins longer instead of doing it once. You may remove your bulky solder from pins with help of desoldering braid / solder wick. That is how you can apply less heat at once and remove bulky solder at once. After you may drag your soldering iron tip on pins only one time with little solder on tip. I usually do this technique and it's better way to not apply heat repeatedly on same pins or area.
Different techniques, same result...
This was just a brief demonstration...
Of course depending on what you are doing, you need to apply more or less heat, remove solder with wick first, etc...
Thank you for watching and for your comment!
👍👍👍
You approach this somewhat like Louis Rossman does. Only he relies heavily on scope views when he's doing work so you'll see what he's talking about. He's so much into anti-Apple ... you have to pick what videos to watch.
😊
I am not an Apple fan either...😋
Thanks, for watching and for your comment!

how do you know which chips hold which data
Hi
On an ECU is pretty much always the same... flash the maps, and eprom configurations and immo... there is sometimes immo data in the flash as well..
Thank you for watching and for your comment!
Have you got any tips ' no pun intended ' on how to remove jelly thanks
What jelly are we talking about?
He must be talking about silicone conformal coating.
On the subject of potting/conformal, have you removed and replaced any SOT16 SOT24 etc. packages where the conformal has seeped underneath the chip and glued it to the PCB?
A recent experience was that I may have overheated the package because it never came "loose" when desoldering. I was more worried about damaging traces.
@@AntiCoruptionCentral
Hi
Yes... many times...
I only heat untill I see that the solder is liquefied... you can check it with the tweezers... if I feel that at that point the chip does not move, I force it up...I might have some video that captures that...
That might be a situation where a microscope and pre-heater would be mandatory - to be able to ensure the molten state has been achieved.
Total loss of "feel" like that is very disconcerting. Damaged tracks is never any fun.
It’s best not to clean the pads with desoldering braid. Using braid improperly is the reason pads get ripped off boards. Instead use flux and add new solder to pads. There’s no reason to completely remove solder from pads.
I agree to disagree...
If you use the correct temperature and technique, no way you are going to rip the pads off... if it is happening to you, you are doing something wrong...
Thank you for watching and for your comment!
👍👍👍
@@LMAutoRepairs It doesn’t happen to me. I add fresh solder to the pads , replace with new part and reflow. It’s easy.
