Atmospheric plasma cleaning
Atmospheric plasma is a surface treatment that has a wide range of applications and is commonly used manually or inline in high‑throughput industrial processes for cleaning, activation, and functionalization of substrates. Since the process occurs at atmospheric pressure, it does not require vacuum chambers. The treatment is fast, effective, and can be precisely targeted.
Relevant industries
Plasma surface treatment serves Semiconductor, Medical Device, Lifesciences, Electronics, Defense, Aerospace, and Automotive markets. It cleans, activates, and functionalizes surfaces for reliable bonding, coating, and assembly—supporting catheter adhesion, biocompatible finishes, rugged electronics, lightweight aerospace composites, and high‑durability automotive components with uniform, low‑temperature, electric charge free surface treatment unit.
Semiconductor
Atmospheric plasma cleans organic contamination, oils, and particulates from wafers, substrates, and components between process steps. It is widely applied to PCB substrates, lead frames, and package substrates prior to critical assembly steps — particularly where vacuum processing is impractical. The plasma pen extends these capabilities by enabling selective area treatment without masking, increasing surface energy on polymer, ceramic, and metal surfaces. Key applications include encapsulant and molding compound adhesion, post-reflow flux residue removal, pre-wire bonding activation, conformal coating preparation, and wafer-to-wafer bonding pretreatment. The plasma pen is equally effective for post-dicing die edge cleaning to remove polymer debris and improve die integrity.
Energy
The plasma pen is used across the energy sector in cleaning, activation, and bonding applications. Applications range from bipolar plate cleaning and activation in fuel cell production, to surface preparation prior to catalyst layer coating, and layer-to-layer bonding in solar panel assembly.
Aerospace & Defense
Atmospheric plasma is used across aerospace and defense for bonding, cleaning, and surface preparation — from small electronic components to large structural panels requiring activation prior to protective barrier coatings. It is also widely used for cleaning optics and lens materials where surface cleanliness is critical for optical performance and visibility.
Automotive
The plasma pen is used to spot treat and activate critical surfaces such as glass and polyurethane adhesive interfaces prior to windshield installation, improving bond strength and long-term durability — essential for ADAS camera and sensor mounting accuracy. It is also widely used for headlight lens cleaning before hard coat and anti-fog coating application. More broadly, the plasma pen activates surfaces wherever two components must be permanently bonded for the life of the part.
Medical
The plasma pen is widely used in medical device applications, from well plate activation to precise treatment of flow channels in microfluidic devices, improving wettability and fluid behavior in diagnostic and point-of-care platforms. A key advantage is the ability to treat specific areas selectively — for example, activating a defined bonding zone while leaving surrounding surfaces hydrophobic. Atmospheric plasma is also used to clean and activate surfaces prior to functional coatings, including drug-eluting, antimicrobial, and chemical-resistant layers.
