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 parts

Problems with Current Method: Does not clean satisfactory

Purpose of Cleaning: To meet vacuum specifications

Product Use: Semi-conductor fabrication

Cleaning Chemicals: Brulin 224

Trial Number Date Run Purpose Success Rating
0 11/26/01 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 11/27/01 To evaluate cleaners using longer times and elevated temperature A follow up test, usually based on company input. 
2 11/27/01 To evaluate successful cleaners using ultrasonic energy A follow up test, usually based on company input. 
3 12/12/01 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 01/24/02 To evaluate baking soda blasting unit A follow up test, usually based on company input.
