  • Elemental Threats to Circuit Boards

     

    Today, the range of when and where we use electronics broadens constantly. Consequently, electronics encounter threats such as water, extreme temperatures, shock, and contaminants. A circuit board, the core of  any electronic, makes it highly sensitive to these threats that cause damage and failure. Manufacturers protect the board’s components with conformal coating. Conformal coating, implemented in the manufacturing of circuit boards, provides protection against threatening contaminants, moisture, and even extreme temperatures. Conformal coating comes as either a specialized coating or a polymer film that conforms to the topography of a circuit board, thus forming a protective shield.

    Circuit board protected by conformal coating.

    When coating anything, the surface must show a level of surface cleanliness for the coating to bond successfully. Furthermore, circuit boards in particular, require highly cleaned surfaces, because of their sensitivity to contaminants. So, managing surfaces in circuit board manufacturing is doubly important. The surface must be clean for the sake of the circuit board and for the success of the coating. …Read More
