In conjunction with ultrasonic energy four products (two aqueous and two semi-aqueous) were found effective in removing the flux. Vacuum drying was found to be the best drying option for the parts being cleaned.
Test Objective:
To find an alternative cleaner that will remove the flux residue from bellows assemblies (eliminate the need for TCE & Methylene Chloride).
Product Use:
This assembly will be used in a switch assembly in autoclaves
To identify cleaning alternative to replace TCE and methylene chloride. Cleaners should be usable in ultrasonic equipment.
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
To further evaluate the two semi-aqueous cleaners from the previous trial.
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
To clean supplied parts using the proposed cleaning protocol.
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
