Hi everybody,
I've tried my new 22 [L] ultrasonic cleaner some days ago with 4x dirty PCBs, especially stained by rosin from welding wire.
First try : only deionized water, no heating, ultrasonic vibrations during 5 [min]. No result
Second try : only deionized water, heating at 40 [°C], ultrasonic vibrations during 10 [min]. No result
Third try : 3/4 deionized water and 1/4 isopropyl alcohol, heating at 50 [°C], ultrasonic vibrations during 15 [min]. A small result.
The attached user manual is a little bit skinny, and poor in images.
Just one thing : these 4x electronic boards have been soldered a "long time ago", in January 2018. Does this parameter matter ?
Sorry, no pictures available, because my smartphone's camera is out of order. Could someone help me ?
