Trial #1
Evaluation of successful products using ultrasonics
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 handheld 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.
All five products were very effective using ultrasonics for two minutes. Table 1 lists the efficiencies for each coupon cleaned.
