Do as graeme in the above post has said and gently push down on atmels at same time. I did this on a 4000 a few weeks back and all ok. Just be careful not to overheat with hairdryer though. I did it using my daughters hairdryer and them things dont half get hot.
Just tried to reheat atmel connections with soldering iron, but i have shorted some of the the connection as there is very small gap between the connections of the atmel, i am finding it difficult to separate them. How do I get around that?
