Plasma, known as the "fourth state" of matter, consists of electrons, ions, free radicals, neutral particles, and photons. Highly reactive plasmas are formed when gases (such as oxygen, nitrogen, and argon) are excited by high-frequency electric fields, microwaves, or direct current power.

When plasma acts on a solid surface, it produces multiple effects:

Physical bombardment: High-energy ions impact the surface, removing contaminants and oxide layers.

Chemical reaction: Free radicals react with organic matter on the surface, decomposing it into gaseous products (such as CO₂ and H₂O), achieving cleaning.

Plasma technology offers different solutions for many types of molecular-level contamination, depending on the subsequent treatment. You can choose from a variety of plasma processes to meet your specific application needs.

Plasma cleaning：Plasma cleaning utilizes low-temperature plasma to physically or chemically modify the material surface.

Surface activation: Polar functional groups (such as hydroxyl and carboxyl groups) are introduced to the surface to increase surface energy.

Etching and modification: Roughening the surface structure at the nanoscale improves wettability and adhesion.

Plasma coating: Functional coatings such as water-repellent, antifouling, and antistatic layers are formed through plasma polymerization.

Plasma technology has penetrated multiple manufacturing industries:

• LED: Improving encapsulant adhesion and improving the transfer process for Mini/Micro LEDs.
• PCBA: Improving solder paste wettability, reducing solder defects, and enhancing conformal coating uniformity.
• Semiconductor: Die bonding, wire bonding, and surface cleaning before encapsulation.
• FPD display: Glass cleaning, polarizer lamination, OLED encapsulation, and optical film processing.
• Plastic: Improving the spraying, bonding, and printing performance of low-surface-energy materials.
• Lithium-ion battery: Activating the electrode/diaphragm surface, improving electrolyte wettability and cycle life.
• Automotive: Headlight lenses, interior spraying, window film lamination, and sensor sealing.
• Consumer Electronics: Mobile phone glass lamination, housing spraying, camera module assembly, and battery packaging.
• Medical: Improving the biocompatibility and coating adhesion of implants, catheters, and dialysis membranes.
