Hello guys,
if after visual inspection traces of corrosions are detected around pins of IC chips and resistors/capacitors, is it really necessary to replace the components?
I wonder if it may be sufficient to desolder components, clean placeholders /pads on the board and return the same components back to the board.
Does corrosion on pins/legs really kill the components?
No long ago, I have repaired 820-3437, by cleaning the green tracesnear U1950. Both R1950 and C1950 had green stuff on their pads, so I put flux, removed componets, cleaned pads and returned the same components. I used alcohol to clean around U195, und reflowd with a bit of flux.
Laptop started working and as far as I know, it still works. But on many youtbe videos, all these components are replaced.
