Trial Number 1

Trial Purpose:

Evaluation of successful products using ultrasonics

Date Run:

08/08/2002

Experiment Procedure:

Five products were selected from the previous trial based on their high efficiencies. The solutions were used at 68 F. The three semi-aqueous products were used at full strength and the two aqueous based products were diluted to 10% in 600 ml beakers using DI water.
Fifteen preweighed coupons were coated with Alpha Metals 615 Flux (67-63-0, 8052-41-3, 8050-09-7) using a hand held swab and allowed to dry. Coupons were then reweighed. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation, then rinsed in tap water at 68 F for 15 seconds followed by an air knife drying for 30 seconds. Once dry, final weights were recorded and efficiencies were calculated.

Trial Results:

All five products were very effective using ultrasonics for two minutes. Table 1 lists the efficiencies for each coupon cleaned.
