  • Parts washers play an integral role in manufacturing, especially on machined parts and bonding surfaces. Prior to coating, sealing, painting, and welding, parts washers help remove contaminants generated from fabrication to facilitate stronger bonds.

    But, for a reliable bond to form, the surface must not only be free of particles, it must also be chemically clean. Thus, quantifying and analyzing parts washer effectiveness in removing chemicals is the key to ensuring the desired surface is achieved.

    The importance of monitoring cleaning processes in preparation for bonding is becoming increasingly necessary as sealing processes are rapidly replacing traditional mechanical fasteners and gaskets.

    However, when sealing, the surface must be clean and clear of contaminants to guarantee the bond. The Surface Analyst monitors and optimizes washer systems to ensure the part comes out chemically clean and ready to hold a reliable bond. …Read More

  • The utilization of composites increases daily in manufacturing as more ways in which to use this advanced material are discovered. Composite is a smart material that provides a lighter weight and stronger product. This advanced material is being used in many different industries, from consumer products like bicycle frames to airplanes. Yet, because the strength is held in the fibrous matrix of the material, composites must be adhesively bonded together as traditional mechanical fasteners can break the fibers and compromise the material’s integrity.

    To guarantee these bonds, BTG Labs’ Surface Analyst™ precisely, accurately, and quantifiably measures the surface’s readiness to bond. BTG Labs’ experience in the field of composites reaches back to the genesis of the Surface Analyst when the USAF turned to the company to engineer a hand-held surface energy measurement device for composite bonding of aircraft. Since then, the Surface Analyst’s composite applications continue to increase and span into many more industries.

    Surface Analyst Applications Examples for Bonding, Coating, Sealing, and Painting Composites

    • Aerospace: satellites, aircraft, and spacecraft
    • Sports and Recreation: sporting equipment
    • Automotive: structural components, drive shafts, interior parts
    • Medical Device: prosthetics, repair equipment, tubing
    • Marine: structural frames and components, fiber glass applications

  • 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
