How To Clean Coating Frames with Metal Parts from Silicone

WHAT IS THE CUSTOMER‘S STORY?

The customer has implemented the manufacturing process, during which the silicone coating is used. Cleaning of cured silicone is very unique and challenging, and we don’t know about any other company which would be able to provide such effective cleaning solutions as DCT. Based on positive references from our current customers, they have contacted us, and then we have received their components for testing in our DEMO center. Furthermore, during testing period, DCT has developed new cleaning agent for the removal of silicone.

WHAT WE TESTED?

DCT R&D team tested sample components in our laboratory.

They tested how to remove silicone based conformal coating from coating frames.

COMPLETE CLEANING SOLUTION BY DCT

We tested two different ways of removing the coating by alcohol-based cleaning agent Proton® 703.
A) with ultrasonic technology
B) with horizontal high-pressure Spray-In-Air

RECOMMENDED CLEANING PROCESS

A) Cleaning system:

Sonix® 355 CRRD

Technology:

Ultrasonic

Cleaning:

Proton® 707 60 min / 40°C

Rinsing:

DI Water / 5 min / 30°C

Drying:

hot air / 45 min / 45°C

B) Cleaning system:

InJet® 888 CRRD

Technology:

horizontal high-pressure Spray-In-Air

Cleaning:

Proton® 707 50 min / 40°C / 2,5 bar

Rinsing:

DI Water / 5 min / 30°C

Drying:

hot air / 45 min / 45°C

Perfect results were observed in both cleaning systems in combination with Proton® 707.

Cleaning time needed for complete removal of the coating was 1 hour in Sonix® and less then 1 hour in InJet® 888.

The silicone layer was really thick and the degree of pollution was high for the testing purposes. Eventought, the results were excellent.

RESULTS OF TESTING

Success rate: 100%

The customer was really pleased with the perfect results of testing with Proton® 703. However, DCT is currently waiting for the newest development pattern of customer’s coating frames. Another test will be done with Proton® 707 as this cleaning agent has been developed only a month after testing with Proton® 703. So the newest type of coating frames will be tested with our newest cleaner for silicons. The old type of coating frames has been already tested with amazing results.
