Low Pressure Plasma Cleaner: Advanced Surface Treatment Technology
Low-Pressure Plasma Surface Treatment is a core technology in modern manufacturing, delivering atomic-level surface cleaning and activation. It is the standard solution for improving adhesion of adhesives, coatings, and paints in electronics, medical, and precision industries. Explore COUSZ’s advanced low-pressure plasma equipment to optimize your production processes.
1. What is Low-Pressure Plasma Cleaner? How Does It Work?
Low-Pressure Plasma Treatment utilizes the fourth state of matter—plasma—to modify the chemical and physical properties of material surfaces in a vacuum environment, typically ranging from 0.1 to 10 Pa.
In this process, the material is placed inside a sealed vacuum chamber. After evacuation, the working gas (such as argon, oxygen, or gas mixtures) is energized using radio-frequency (RF) or microwave power to generate plasma. This produces highly reactive species, including ions, electrons, and free radicals.
Key advantages over atmospheric plasma:
– Superior uniformity: Low-pressure plasma allows particles to move freely with fewer collisions, ensuring even treatment across complex structures, microholes, and 3D details.
– Precise process control: By adjusting the type and concentration of reactive species via working gases, treatment intensity and deposition can be customized for specific materials.
2. Core Functions of Low-Pressure Plasma Equipment
Low-pressure plasma systems provide three primary benefits for surface treatment:
2.1 Surface Cleaning
This is a dry cleaning process, eliminating ultra-thin organic contaminants such as oils, silicones, or fingerprints at the atomic level without chemical solvents.
Mechanism: Reactive species (e.g., active oxygen) oxidize organic contaminants into CO₂ and H₂O, which are then removed by vacuum pumping.
2.2 Surface Activation
Low-pressure plasma introduces polar functional groups (-OH, -NH₂) onto material surfaces, significantly increasing surface energy. This improves wettability and provides strong chemical bonding sites for adhesives, coatings, or inks.
2.3 Plasma Coating / Deposition
Low-pressure plasma systems can deposit functional thin films through Plasma-Enhanced Chemical Vapor Deposition (PECVD). Examples include:
– Anti-wear coatings
– Hydrophobic layers
– Biocompatible functional coatings
These coatings enhance product longevity and performance.

4. Technical Advantages and Industry Applications
Low-pressure plasma systems offer unmatched uniformity, temperature control, and material compatibility:
4.1 High Treatment Uniformity and Temperature Control
All parts in a batch receive consistent plasma exposure, ensuring repeatability and uniform quality. The process does not significantly increase material temperature, protecting sensitive components.
4.2 Applications in Advanced Industries
– Medical & Biomedical: Absolute cleaning and activation of implants and medical devices.
– Optics & Electronics: Plasma coating systems apply functional layers on lenses, displays, and touch panels.
– Aerospace & Composites: Surface preparation for adhesives on composite materials requiring maximum bonding strength.
5. Choosing the Right Low-Pressure Plasma System
Key factors when investing in a low-pressure plasma system:
– Gas and pressure control: Must include Mass Flow Controllers (MFCs) for precise gas delivery.
– Chamber design and power source: RF power should be adjustable to control surface energy effectively.
– Recipe programming and storage: Advanced systems offer user-friendly software to store and replicate optimized treatment recipes.
