Greetings! I just read your article about how you managed to solder the broken pins of an IC and recover the company data. Very impressive job indeed! I am an electrical engineer student from Portugal and I am really thrilled with these type of projects. If you had a solution for a problem I would be really appreciated. In short words, I have an lcd c.board with two IC´s in which, one of them burnt (tiny burn hole, Vcc & SDA shorted to GND). With a little of research and only knowing from the IC information (L02W), came up to realise I am probably working with a 2kb eeprom ic (https://pt.mouser.com/ProductDetail/ROHM-Semiconductor/BR24L02-W/?qs=sGAEpiMZZMuVhdAcoizlRQzLrnXYhCqveisnU%252byKyxI%3D). (https://fr.aliexpress.com/store/product/Free-shipping-10pcs-lot-L02W-new-original/1918854_32638364648.html) Identical to mine but not exactly it. Mine is a mini-sop8. I thought of two solution, try to read & copy the good ic data using the method you used (converting sop8 to DIL adapter), at my university, still not knowing if they have identical data OR, try to recover the lost data from the burnt IC and write it on a new IC. What would you sugest me to do with your experience? Thank you for your time! Have a good day,
Mike.

I checked this eeprom programmer what about you asked, the MiniPro tl866. I think it is a nice programmer. It is worth the money.
The software is nice and not hard for understanding and the whole product is clear and nice.
So, buy one and introduce it. 🙂

Here is some starting point article what maybe you like to know.
This area is from my time when I learned about using this stuff and how to get access to some other stuff.

Thanks for supporting my article.
When I back in my lab where I actually work I will check about your problem and try to figure out a way how to read the content from that kind of device.

My best regards.

Hi!
Thanks for supporting my article.
I have no clue right now about web's or video's about eeprom programming but I can say, the first step by me is to look into the data sheet of the desired eeprom. There should be written the most stuff.
You have to own quality tools to work with eeproms. I think the most of the stuff is done by the eeprom programmer. So, you make one for you or you buy one.
When you have a good eeprom programmer, then you can concentrate on the repair stuff. Otherwise you are in trouble.
If I see an eeprom in a device what I'm repairing then I read out the content and save it to my PC. Maybe I can reuse the content in some other situation. This is my most valuable task when I recognize an eeprom.
I also get the content from the internet, from forums from guy who have a device in their service room and can read out for me. Always ask if you need something, otherwise nobody knows does you need help.
If this dos not work then I check on some electronic junk yard for a device and then hopefully I find what I need.
This is some of my steps of my researches...
If I can hep you please feel free to ask me.
My best regards.
