  • Masking and de-masking systems and processes
    Patent number: 10786981
    Abstract: An automated masking system includes a substrate loading apparatus designed to hold a plurality of substrates, a first masking material application station designed to automatically apply a first masking material to a portion of the substrate, and a second masking material application station designed to automatically apply a second masking material to a portion of the substrate, the second masking material being different than the first masking material. The system includes a first dispensing apparatus and a second dispensing apparatus that move relative to the substrate in a repeatable motion. The substrate moves automatically from the first masking material application station to the second masking material application station.

  • Method of masking and de-masking
    Patent number: 10448519
    Abstract: A method of masking a feature of a substrate using a fixture includes removably coupling a fixture to a first side of the feature of the substrate, the fixture including walls configured to abut sides of the feature and extend beyond a top surface of the feature when the fixture is removably coupled to the first side. The method further includes applying a masking material to the top surface of the feature. The method further includes removably coupling the fixture to a second side of the feature, the second side opposing the first side, the walls of the fixture configured to abut the sides of the feature and extend beyond a bottom surface of the feature when the fixture is removably coupled to the second side. The method further includes applying the masking material to the bottom surface of the feature while the fixture is removably coupled.
