Do you have any directions for unsoldering and resoldering the CCD to the PCB? Thanks

Your email asked for more detail so here is what I have. I have removed the "L" shaped board with the CCD mounted. I'm not sure if the problem is the CCD or the board to which it is attach so I was trying to purchase the assembled board. I was a little concerned about soldering the CCD to the board because I thought it may be sensitive to heating the leads if I overheated them. Do you have any details on a way to test the board or CCD or how to go about safely de-soldering and soldering the CCD to the board. THanks
