CIF Laboratory Plasma Cleaner (CPC-F, CPC-Fplus)

Working Principle of Plasma Cleaning Machine

Plasma, like solids, liquids, and gases, is a state of matter known as the fourth state. Matter typically exists in three states: solid, liquid, and gas. However, there are special cases where a fourth state exists, such as in the ionosphere of Earth's atmosphere. Substances that exist in the plasma state include electrons in high-speed motion; neutral atoms, molecules, and groups of atoms (free radicals) in an active state; ionized atoms ormolecules; unreacted molecules and atoms. Despite this variety of particles present within plasma, the substance remains generally electrically neutral.The plasma cleaning machine generates high-energy disordered plasma in thevacuum chamber through the RF power supply under a certain pressure. By bombarding the surface of the material to be cleaned, it changes and optimizes the surface properties of the material, achieving the purpose of surface cleaning and modification.

Applications

Plasma cleaners are widely used in materials science, microelectronics, semiconductors, circuit boards, LEDs, microfluidics, photoelectric solar energy and other fields for the purposes of material surface cleaning, activation, modification and etching.

Function & Features

1. Intelligent interactive interface: Featuring a 7-inch color touchscreen, the system supports bilingual operation in Chinese and English. It enables real-time monitoring and automatic adjustment of process parameters. With 20 pre-programmed recipes, the system allows for efficient storage and traceability of process data.

2. Reliable control system: It adopts PLC for full-process control and supports both manual and automatic operation modes to ensure a stable and reliable cleaning process.

3. Bidirectional intelligent vacuum control: The system can precisely control the vacuum degree through two modes of adjusting gas flow or chamber pressure, providing more flexible and intelligent process  control to meet diverse precision processing requirements.

4. Precise gas management: Equipped with gas float flowmeters or mass flowmeters, it supports various gas sources such as oxygen, argon, nitrogen, hydrogen and mixed gases, with high control accuracy.

5. Clean and anti-pollution design: Equipped with gas backfill and purge function, and fitted with HEPA high-efficiency filters to effectively prevent secondary pollution.

6. High-quality material structure: The vacuum chamber can be made of 316 stainless steel or quartz, and the entire vacuum pipeline system is made of 316 stainless steel, which is corrosion-resistant and pollution-free. 

7. Humanized operation design: The operation panel is designed at a 60° angle, which conforms to ergonomics, with a friendly interface and convenient operation; the upper control and lower cabin structure is compact, saving space; the front panel is concave, protecting the flowmeter and cabin door from damage.

8. Highly efficient and stable process: The treatment process is fast, uniform, and repeatable, with no pollution; the sample processing temperature is low, avoiding thermal damage and thermal oxidation.

9. Comprehensive safety protection: The power is automatically cut off when the door is opened, and it is equipped with multiple protection mechanisms such as controllable pressure relief to ensure the safety of operation and samples.

10. Showerhead Gas Inlet System: It adopts a multi-channel gas intake design, effectively solving the uneven airflow issue of traditional single-hole intake and ensuring uniform and consistent processing results.
