Scotch-Brite cleans very well oxidized pads. I'm working with larger bga chips(graphic cards). After Scotch-Brite cleaning, soldering is much simpler with less flux and no cold joints. I admire Your work. I hate any kind of glue on bga chips.
@@pablopicasso6173 thank you for your advice regarding the use of scotch-brite , sadly it's not available where i live , is it some kind of a cleaning chemical ? I'm using the following method to remove oxidisation from BGA chips, put some flux on the BGA chip and apply some soldering paste " no need to be freshly picked out the container you may use left overs from previous repairs " then spread the paste on the IC using a Qtip while applying heat with the hot air this will work like a sharm 😉.
Nice work. 😎

@@VDD_MainRepairs Plumbers use something similar to Scotch-Brite for copper pipes cleaning before soldering. Check it :)
Sometimes when everything looks really bad, I'm using soldering acid. It's phosphoric acid or hydrochloric acid.
What about those spots @22:01 , were those ripped off?
Ripped off not connected pads
