    if you dont have eerpom raeder try to buy it in ebay,amazon like ezp2010 or ezp2019 ,rt809f etc

    Ok, well. I have never done any of that and I honestly thought this would not be as complicated..... hum. Let's say I go for it, but I have never desolded and resolded anything in my life.

    Could you put in here a few links to something I can buy in amazon for such purpose? A link to a desolder and a link to a solder.

    I fear that if I buy something cheap and random I would just burn the board. So, I would like first to evaluate the options and associated costs before making such a decision.

    Thank you very much.
