    Today, the mobility of electronics allows us to broaden the range of when and where we use them. Consequently, electronics encounter threats such as water, extreme temperatures, shock, and contaminants. BTG Labs’ Surface Analyst™ helps electronics manufacturers build a product to stand up to elemental threats. This fast, easy, accurate, and non-destructive handheld device verifies surface cleanliness levels in order to bond, coat, and print properly on a surface.

    Typical Surface Analyst Applications in Electronics Manufacturing

    • Monitor cleaning processes for solder flux
    • Verify surface readiness for conformal coating in circuit board manufacturing
    • Ensure strong bonds on solar panels
    • Guarantee bonding of print on electronics
    • Predict adhesion for UV cured adhesives
    • Measure cleanliness levels of silicon wafers used in integrated circuits
    • Ensure coatings on composite conductive equipment
    • Inspections on glass used in consumer electronic devices

  • 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.

    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
