Damage Control

Scogin stressed the importance of determining an exact washout time. He explained: "To make sure the entire unexposed polymer is washed away from the plate, it's necessary to establish the wash rate. This is done by putting a piece of unexposed polymer through washout for 'x' amount of times, then measuring it with a micrometer to see exactly how much polymer was washed away. It can then be calculated how long the washout [period] will need [to be]."
