Trial #2
To clean client supplied parts using successful cleaners
Five products from the previous trial were used to clean several supplied parts. Three products were used at full strength and the two aqueous products were used at 10%, diluted with DI water in 600 ml beakers.
Four products were degassed for 5 minutes in a Crest 40 kHz ultrasonic tank and the fifth product was degassed in a Branson 40 kHz ultrasonic tank.
Four small boards were cleaned in the Crest unit, and one large board was cleaned for 5 and 10 minutes in the Branson tank. Parts were dried using air blow off for 2 minutes at room temperature. Parts were initially viewed for cleanliness and then sent back to the client for further inspection.
Most of the products appeared to remove the flux/solder from the circuit boards. The following are the observations made during cleaning
