HOW TO DESOLDER EEPROM, WHERE WHEN NOT MELT WELDING AND DAMAGE THE EEPROM OF GRAPHITE

[javiercj]

Hello friends

you happened to try to remove the welding of an eeprom of 8 pins of an airbag unit circuit, there is no way to remove the Tin.

I have done many and micros motorolla etc.

Remove welding with station, hot air and without any problem.
Therefore well today has gone.

was a unit of airbag and the eeprom circuit there is no way to desolder. to the finao graphite from the eeprom has burned and not
has desolder
there is any product that does not happen more, avoid damaging the circuit and not burn the eeprom memory, and allows desolder.

thanks

hope answer

circuit came with a kind of enamel even so there is no way

thanks

you should have used acetone on it first, and rub it or lightly scratch it. afterwards desolder usind the smallest adapter for the hot air, directing the flow only at the pins.

Hi
thanks for responding.

Of acetone not what had done, that usually make either scratched before desolder to clean a little lacquer.

But I will try to use first acetone.

If air directly address it pins and when micros motorolla are what I do is the first direct hot air in the pins and also about the micro.

thank you very much for helping

temperature must be used with the station of hot air??

thanks

hello.

Thank you all for help.

But the damage to the circuit was done,
to burn the tracks of the circuit

I finally managed to remove the eeprom but the tracks are burned

There may be possibility to connect an eeprom again

but with detail on image to see the photo of the tracks of the circuit of airbag unit

airbag control box is:
airbag 550 80 44 00 8200018830

You can help

But in the image of the circuit you can see the tracks that is below the eeprom

I hope help

Thank you

Where can I find?

follow the tracks and join the eprom pins with cables to the next possible point. skip the tracks

If.

that do when leave the track.

but as they have broken several tracks, no longer is that track corresponds to each leg of the eeprom.

Therefore needed to see a clear picture with the eeprom removed the switchboard of airbag.
circuit
thank you

[Youneselm]

thats also an option, but not so clean.
with the pads its verry clean and profesionel job.
