Ultrasonic Cleaner Cleaning Fluid Temperature(s) Concentration
MI40 Ultrasonic HP imaging Oil No heat, room temperature 100%
Versa 120 Ultrasonic Galvex 18.01 50°C 5%

Process for removing ink:

An MI40 ultrasonic tank was diluted with 100% concentration of HP imaging oil, the oil was tested and showed good cavitation. The oil was not heated as this posed a potential hazard. The TIC board was placed in the basket and cleaned for a cycle time of 20 minutes in the imaging oil. The clear housing was then cleaned using the same process as the TIC board.

Upon inspection both the board and the housing showed ink residue remaining, Both parts were then cleaned using the aqueous process using Galvex 18.01 cleaning fluid at a 5 % concentration for 10 minutes followed by a tap water rinse, DI water rinse and a hot air dry. Note: The tanks were filled to weir level so both the board and the housing was positioned in the basket standing up and was fully submerged.
