Hello there,
How to clean in liquid contact devices.
If the liquid contact devices are not well cleaned, they will still fail after a while.
I usually clean with thinner and alcohol.
I am waiting for your suggestions.

hello

if you see still oxidation on components you can remake the joint solder with flux and fresh tin using the solder iron and fine tip .
Inside IC the best thing is remove the component and reballing it or but this could be temporary solution ,much flux upper ic and carefully a reflow with hot air.
The ultrasonic washer is another alternative but before every attempt I have described.

Which liquid you recommend in the ultrasonic washer.

I do not recommend IPA (isopropyl alcohol) because of inflammability ... I have seen how it works well TERMOSONIK PCB non-flammable water-based..in alternative go on the web on the websites of generic electronics.
