Trial Purpose:
To evaluate follow up product on flux removal.
Date Run:
06/18/2008Experiment Procedure:
One product was used at full strength and room temperature for removing the supplied flux. Three preweighed aluminum coupons were coated with two layers of the RMA flux using a handheld swab. Once dry, coupons were weighed a second time to determine the amount of flux added. Three coupons were manually wiped using the same method as previous trials, soaking the rag and wiping the surface. Coupons were wiped briefly with a dry wipe to remove any residual cleaner. Final weights were recorded, and efficiencies calculated for each coupon cleaned.
Trial Results:
The Green Works Glass cleaner worked well at removing the flux. The table lists the amount of flux added, the amount remaining and efficiency for the three coupons cleaned.
| Cleaner | Initial wt | Final wt | % Removed |
| Green Works Glass | 0.0186 | 0.0046 | 75.27 |
| 0.0232 | 0.0005 | 97.84 | |
| 0.0169 | 0.0005 | 97.04 |
Success Rating:
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.Conclusion:
The Green Works Glass cleaner could be used as potential cleaner for the flux operation based on laboratory evaluations.
