Trial Number 2

Trial Purpose:

To clean client supplied parts using successful cleaners

Date Run:


Experiment Procedure:

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.

Trial Results:

Most of the products appeared to remove the flux/solder from the circuit boards. The following are the observations made during cleaning
