Project Number 1

Summary:

Several stages of testing was conducted to find a cleaner that could be used on all of the substrates the client dealt with. There was not one product that could do them all. Labs recommendations have been tested at facility.

Test Objective:

Replace TCE vapor degreasing operation with an environmentally improved system/process

Product Use:

Specialty multilayer ceramic capacitors
Trial Number Date Run Purpose Success Rating
0 02/25/1998 Preliminary test of selected aqueous cleaners Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
1 02/28/1998 Determine if temperature would aid cleaning Test incomplete or inconclusive.
2 02/28/1998 Determine if ultrasonics would aid cleaning Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
3 04/01/1998 Find cleaner for plastic bottles. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
4 05/20/1998 Find cleaner capable of removing paint Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
