What do Nokia use to glue LCD/ main board cables with ? Answered
Opening a Nokia 1661 mobile phone (its an uber-cheap UK phone ) to replace the LCD, I have the usual orangey flex PCB material off the LCD, basically GLUED to the mating surface on the main PCB. The old display tails peeled off, but I can't identify the strange grey glue they used to mate the connections.
Has anyone any ideas ? It almost looks like partially cooked solder paste, but that would conduct all over, and I can't see any isolation. Its not "rubbery" that I can tell.
