  • Method for manufacturing water resistant printed circuit board
    Patent number: 11439024
    Abstract: A method for manufacturing a water resistant substrate comprises a first step of providing a substrate. The method proceeds with a step of populating at least one component onto the substrate. Next, the method includes a step of cleaning the substrate including the at least one component to form a cleaned substrate. Then, the method proceeds with depositing a multi-layered water resistant coating onto the cleaned substrate.
    Type: Grant
