Plenty on You Tube, it is actually fairly easy as long as it not too fine a spacing. Remember to brighten the PCB pads with a fibre pen, and wipe with IPA before starting. Then the most important thing to remember is use plenty of flux. With an ordinary soldering iron with lead tin solder.

I would suggest you find an old satellite receiver or computer board and get some thing like this,
https://www.ebay.co.uk/itm/ChipQuik-...En9v:rk:6:pf:0 and have fun removing and practice soldering. you will use less than an inch of alloy on each chip and if you save it can be re used. May save ruining a board and if you did have to remove a chip from the main board you have some ready.
