Toyota - Blue film covering Solder joints

[munkss]

Hello i was gonna edit km on this toyota but after removing the dash i see that this board looks like it has been repaired before. And over the eeprom i see this blue film/glue. I've never seen this before so im not sure how to remove it or what it really is.

Anyone have experience with this before? Can i just use hot air over is and remove the chip? or will there be any problems?tundra.jpg


Thanks in advance.

This blue material is original, clean with thinner solvent.

Thanks so much for the reply, are you talking about regular paint thinner or is there any kind of special i need to use to not damage the board?

That's right, I use to remove and then clean everything with isopropyl alcohol.

use a tweezer before cleaning and try gentle to remove as much you can, if you lucky may not need to use a cleaner, sometimes they come off very easy...

Epoxy/conformal coating removal pens are cheap off Amazon. They contain tetrahydrofuran and can be refilled if you have a funnel with a tight fit.
