In the field of precision optoelectronic manufacturing, the performance and lifespan of carbon dioxide radio frequency lasers often start with the ultimate cleanliness in the production process. Micron-sized dust, grease or fingerprint residues are sufficient to become a fatal obstacle to laser energy transmission. Ultrasonic cleaning technology, with its high-frequency cavitation effect that penetrates deep into micro-pores, has become the only way to ensure the cleanliness of core components. This article will focus on the key components that must rely on ultrasonic cleaning in the production process, and introduce in depth the core advantages of the "Carbon Dioxide RF Laser Ultrasonic Cleaning Machine VGT-409FZA" specifically designed for such applications.

1. Key components for ultrasonic cleaning in the production of carbon dioxide RF lasers

1. Laser Discharge Tubes:

Pollutants: Processing residues (metal shavings, polishing paste), fingerprints, grease, environmental dust.

The necessity of cleaning: The cleanliness of the inner wall of the discharge tube directly affects the uniformity, efficiency and stability of gas discharge. Any residue may cause abnormal partial discharge, power drop or premature aging. Ultrasonic waves can thoroughly remove the particles adhering to the complex inner walls.

2. Radio frequency electrode (RF Electrodes):

Contaminants: Metal processing oil stains, oxide layers (slight), fingerprints, dust, and residues of soldering flux (if applicable).

The necessity of cleaning: The cleanliness of the electrode surface is crucial for the efficient coupling and uniform distribution of RF energy. Oil stains or oxide layers can increase contact resistance, leading to uneven heating, reduced efficiency and even sparking. Ultrasonic cleaning can effectively remove surface film layers and particles.

3. Optical Mirrors & Lenses (Output mirrors, rear mirrors, folding mirrors, etc.):

Contaminants: Fingerprints, grease, dust particles, detergent residues, water stains.

The necessity of cleaning: The cleanliness of optical lenses is the lifeline of the laser's output power, beam quality and stability. Micron-level contamination can cause scattering, absorption loss, and even lead to overheating and damage of the lenses. Ultrasonic cleaning offers gentle and thorough cleaning, avoiding the risk of scratches caused by manual wiping.

4. Windows (such as resonant cavity Windows, gas seal Windows):

Contaminants: The same as optical lenses.

Necessity of cleaning: Window panels also require extremely high light transmittance and low loss. Pollution will directly affect the laser passage efficiency and may be ablated by high-power lasers. Ultrasonic cleaning is a standard process.

5. Gas Lines & Fittings:

Pollutants: Metal debris, oil stains, fingerprints, particulate matter.

The necessity of cleaning: A clean gas path is the key to ensuring the purity of laser gas and preventing contamination of the discharge area. Residues can contaminate the gas, affect the performance of the laser, and even clog precision valves. Ultrasonic waves can effectively clean the inner walls of complex pipelines.

6. Metal Housings/Cavity Components:

Contaminants: Machining oil stains, coolant residues, fingerprints, dust, metal shavings.

The necessity of cleaning: Although not directly involved in the optical process, the cleanliness inside the casing is crucial for preventing contaminants from migrating to the core areas (such as lenses and discharge zones) during the operation of the equipment. Thorough cleaning before assembly is a good practice. Ultrasonic waves can efficiently remove oil stains and debris.

Ii. Analysis of the Core Advantages of the Carbon Dioxide Radio Frequency Laser Ultrasonic Cleaning Machine VGT-409FZA:

1. Excellent cleaning ability:

High-frequency precision cleaning (typically 40kHz or higher) : It generates smaller and denser cavitation bubbles, with milder energy but stronger penetration. It is particularly suitable for cleaning laser optical lenses, coated surfaces, precision electrodes, etc., effectively removing sub-micron particles and stubborn film contaminants, while minimizing the risk of damage to the greatest extent.

Adjustable power density: Users can flexibly adjust the ultrasonic power according to the tolerance of different accessories (such as sturdy electrodes vs. delicate lenses) to achieve precise and safe cleaning results.

Optimized transducer layout: Ensure that the sound field distribution in the cleaning tank is uniform, with no dead corners, and guarantee that each component and each surface can achieve consistent cleaning results.

2. Stringent materials and craftsmanship ensure cleanliness:

All-stainless steel structure (SUS304/SUS316L) : The inner tank, outer shell and mesh basket are all made of high-quality stainless steel, which is corrosion-resistant, anti-pollution and easy to clean, eliminating secondary pollution and meeting the high cleanliness standards of the semiconductor and optoelectronics industries.

Mirror-polished inner tank: The interior of the tank is as smooth as a mirror, significantly reducing the adhesion of contaminants and facilitating thorough flushing and daily maintenance.

High-purity water /DI water compatible design: Particularly suitable for the strict requirements of rinsing optical components with high-purity water after cleaning, effectively preventing water stains and ion residues.

3. Intelligent and humanized design:

Microcomputer intelligent control system: Clear digital display, precise setting and control of cleaning time, temperature (with heating model), ultrasonic power and other parameters, simple operation and good repeatability.

Multiple safety protections: Equipped with over-temperature protection, over-water level protection, leakage protection, etc., to ensure the safety of the equipment and operators.

Noise reduction design: Optimize the structure to reduce working noise and improve the working environment.

Large-capacity customization: The "FZA" model usually represents specific size specifications (such as tank body size), and users can customize it according to the actual production volume and accessory size to meet the production line requirements.

4. Efficiency and reliability:

Fast and efficient: Compared with manual or immersion methods, ultrasonic cleaning can several times increase the cleaning efficiency and shorten the production cycle.

Stable and durable: The core components (transducers, generators) are selected from high-quality brands to ensure the long-term stable operation of the equipment and reduce maintenance costs.

Solvent compatibility (specific model configuration needs to be confirmed) : Some configurations can be compatible with the use of specific cleaning solvents (such as ethanol, IPA), enhancing the ability to remove organic contaminants such as grease (when using flammable solvents, safety regulations must be strictly followed and it must be confirmed that the equipment has explosion-proof and other characteristics).
