Project Number 1
Summary:
After evaluating several aqueous products with limited success, baking soda blasting was demonstrated to the client as being very effective in removing the salts from the steel parts.Test Objective:
To find one chemical to clean our contaminated partsProduct Use:
Semi-conductor fabrication| Trial Number | Date Run | Purpose | Success Rating |
|---|---|---|---|
| 0 | 11/26/2001 | Preliminary evaluation of selected products. | Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary. |
| 1 | 11/27/2001 | To evaluate cleaners using longer times and elevated temperature | A follow up test, usually based on company input. |
| 2 | 11/27/2001 | To evaluate successful cleaners using ultrasonic energy | A follow up test, usually based on company input. |
| 3 | 12/12/2001 | To evaluate additional cleaners for the removal of the chemical vapor deposition | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 4 | 01/24/2002 | To evaluate baking soda blasting unit | A follow up test, usually based on company input. |
