The trick to getting the ribbon and PCB off is to add more solder!! add a big blob until there is enough solder that all three pins are immersed in it. Then all you have to do is heat the blob up, and it melts the solder around all three pins. Then just simply lift while keeping heat applied. If only the first layer comes off, then just do the same thing
Kenom timed me a few nights ago and I got all the stuff off, from start to finish, in around 56 seconds. Its not too hard it just takes practice and the right technique.
