One day the faithful Asus RT-N16 suddenly died.
Power supply was swapped yet there were no lights.
Post-mortem examination revealed a swollen capacitor (16V 680uF).
Due to double sides board with lots of vias, and crappy RoHS solder, de-soldering required hot air gun.
I didn’t have 16V 680uF capacitor handy, so I improvised with a very tall 25V 1000uF capacitor. Again, solder would not take with soldering iron, only with hot air gun.
I have checked the rest of the caps (on board) and they were all within the spec.
The router came alive after C110 replacement.
Measuring the bad cap resulted in ~92uF…
