  • A Beer with Giles Dillingham

    by Emily Walsh April 2017

    In 1987, Giles earned his PhD and moved to Midland, Michigan to begin laboratory work at Dow Chemical.

    The office of Giles Dillingham is unique, eclectic, and full of resources; very much like Giles Dillingham. The corner office is filled with books, antique tools, paintings by his beloved wife, family photos, and of course, a very nice stereo set-up.

    Giles, BTG Labs’ Founder and Chief Scientist, can often be found typing eagerly away at a report while listening to classical music, or seated at the Cherrywood table, collaborating with colleagues.

    One Friday evening, as the Cincinnati sun began to sink, I shared an end of the week beer with Giles in his lovely office to hear the origin story of BTG.

    Emily: So, Giles, you started BTG Labs. Where did it begin?

    Giles: Well, after I finished my PhD at the University of Cincinnati, I had a job waiting for me at Dow Chemical up in Midland, Michigan. And, I worked there for five years in a variety of assignments, mostly in polymer processing and surface properties. Central Research at Dow in the 90’s was an amazing place to work.  It was a very academic environment with amazing scientists from all fields. I spent most of my time in the laboratory. I learned and grew a whole lot.

    E: And, then what? …Read More

  • Medical Device Applications

    by Emily Walsh February 2017

    BTG Labs’ origins are in the research and development of adhesives and coatings, including the development of a corrosion resistant antimicrobial coating–often used in the medical device industry. The Surface Analyst is the ideal surface cleanliness gauge for the medical device industry in that it is completely non-destructive, precise, quantitative, and able to measure on various substrates including rough, convex, and concave surfaces. BTG Labs’ twenty plus years of expertise can assist in the optimization of medical device manufacturing processes to meet the highly-tailored specs of this industry to manufacture more reliable, fail resistant products.

    Monitor

    • Layers of silicone wafers prior to bonding
    • Sanding and solvent wiping on carbon fiber and titanium for prosthetics
    • And identify the presence of detrimental silicone in a bonding step
    • Flame treatment on medical devices including catheters
    • Plasma treatment on catheters prior to bonding luers
    • Surfaces preparations prior to solvent bonding

    Validate

    • Microbial lubricious coating and uniformity on catheters
    • Surface cleanliness of stainless, aluminum, titanium, and polymer devices
    • Sterilization methods such as ultra-sonic baths and vacuum plasma chambers
    • Audit concerns with shelf-life and uniformity of antimicrobial coatings …Read More
  • water droplet on circuit board

    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
