The workshop will feature keynote presentations and many discussions about emerging technologies in wearable, portable and implantable medical electronic devices. We’re excited to be a part of the event and hope to see you there.
Parts washers are the heavy-duty, hardworking machines that have become irreplaceable staples in any automotive or machined part manufacturing process. As manufacturing processes have become more sophisticated, the industries using parts washers includes not only industrial metals and aerospace materials but also more delicate applications such as medical implants and electronic devices.
But what are the Critical Control Points within a parts washer system? What are the elements that get overlooked and result in adhesion failure even though the parts SEEM clean?

There’s a logical fallacy akin to a “what’s good for one is good for all” mindset that is devastating when applied to surface treatment in adhesion processes. Polymers are rapidly being developed and synthesized for niche applications to push the limits of current physical properties of materials. Polymers that are available today did not even exist a few years, or even months, ago. These different materials possess very particular molecular qualities that require distinct treatment approaches in order to compensate for their differences.
In order to utilize these cutting-edge plastic technologies, manufacturers need to be aware of the effect on the full material system – the baseline material, the adhesion, and outcome of bond performance.
The chemical make-up of the baseline material surface is where it all begins and controlling this aspect of the process can stop adhesion failure at the source. This is, however, often the most overlooked and least understood component of successful adhesion.
The pervasiveness of electronics in every manufacturing industry has provided unique challenges. Manufacturers are tasked with protecting these components
in environments that make
electronics vulnerable to even minute amounts of moisture, debris and environmental contamination.
A useful solution to this problem is conformal coating. Conformal coating is a thin (usually 25-75µm thick) chemical or polymer film (parylene and acrylic are popularly used, depending on the application) that covers an electronic component to act as a barrier against contamination and a defense against moisture. While, this capability massively enhances the protection of, and therefore the reliability of, electronics, manufacturers have been overlooking a key element to dependability in this system: surface condition.
Here are four major factors that could lead to poor adhesion which manufacturers are often unaware of the impact they have:
Plastics are ubiquitous a material as they come, and there is nary an industry that does not utilize them in an adhesion application; medical device, automotive, aerospace, consumer goods, and flexible film and packaging industries all exploit the versatility of polymers in manufacturing. Take a closer look at medical device and automotive industries and you’ll find that the same polypropylene used to make car bumpers in the automotive is also used to make life-saving implantable medical devices.
Polymers are generally chemically stable materials. While this is a desirable quality for other purposes, it is the industry’s greatest challenge to overcome for adhesion applications (coating, bonding, printing, priming and painting). In order for these materials to adhere successfully they have to undergo some type of surface activation process, like plasma treatment. This process will impart chemically reactive groups on the surface and increase chemical reactivity. This reactivity is a quantifiable material property called surface energy. Plasma treatment is a convenient, cost effective means of achieving surface activation of polymers. Before the plasma treatment can accomplish the proper activation of the surface, the chemistry of the polymer must be considered.
This week BTG Labs and Plasmatreat got together to co-present a webinar that de-mystifies plasma treatment as it relates to polymer chemistry.
Understanding surface state at each manufacturing step will allow you to gain complete control over your surface treatment and bonding operation. Here at BTG Labs, we provide a process control check that quantifies that surface state with a simple number.
Control the process, control the number, control the product.
This Tuesday, December 11 at 2pm EST we’ll be partnering with Plasmatreat, a developer of surface treatment systems, to present a webinar hosted by Plastics Technology magazine. Dr. Giles Dillingham, BTG Labs’ CEO and Chief Scientist, and Khoren Sahagian, Chief Process Engineer and Applications Manager to Plasmatreat USA, will discuss the relationship between polymer chemistry and the development of optimal plasma treatment recipes. Plasma treatment is the cutting-edge surface processing technique of polymers for critical adhesion applications. It is increasingly crucial to know how to control this process, know how the chemistry of your surface will affect the treatment and know your target number before and after treatment.

BTG Labs’ CEO and Lead Scientist, Dr. Giles Dillingham and Research and Development Chemist, Brooke Campbell recently collaborated with NASA scientists and researchers from the Department of Electrical and Computer Engineering at the University of Virginia on an article published in the journal of the Society for Applied Spectroscopy.
The article covers research into the sensitivity of laser-induced breakdown spectroscopy (LIBS) and how it compares to x-ray photoelectron spectroscopy (XPS) to detect and measure surface silicone contamination.
When a material begins its journey through a manufacturing process it becomes crucial to know and control everything that happens to that material as it makes its way down the line. There are two major factors to consider when understanding and controlling what happens to the surface of that material: the actual physical space of the warehouse and the time it takes to get through the entire process of being bonded, coated, painted, sealed, glued or printed. If you don’t know precisely what is occurring at each Critical Control Point and you don’t continually monitor the surface throughout the duration of the process, you could be trending towards adhesion failure and not even know it.
