This is VRM, not GPU area. Without any heatsink I guess.
Heatsink on everything including ram and VRM.
Guys thank you for all your suggestions!
I took some old controller boards with 0.7mm or smaller diameter pads and tried all the suggestions
to see what worked best.
By far the easiest, cleanest, safest and more effective solution was to use a syringe.
You hold the needle on top of the pad almost vertically and while applying heat with the soldering
iron you quickly blow air with the syringe. It worked everytime with perfect results!
A combination of
Deathwish's and
wraper's method.
I've tried holding the board vertically and using the sucker from the back of the board, but it was
a bit cumbersome to align the tool and the soldering iron. It worked but not all the times and it
was more difficult for components that were in the middle of the board.
I've also tried Mike's suggestion that seemed intuitive but it worked some times and if the pad hole
was small it was more difficult. Maybe surface tension was greater than the acceleration produced
by the hit. Also I am not sure if that method does not damage some solder joints, especially surface
mount ones.
The syringe needle blower worked like a charm!
Thanks.
(Maybe comparing all the different methods would be a good YouTube tutorial!)
