Non-Contact PCB Board Vacuum Cleaning Machine

Technical Specifications: - Dimensions: 1180mm (Length) x 1490mm (Width) x 1850mm (Height) - Power Supply: Three-phase 380V, 50Hz, 6.5 KW - Board Thickness: 0.06-8mm - Maximum Board Size: 660mm x 660mm - Conveyance Speed: 1-10 meters/minute

Operational Principle: The machine employs a dual air-knife structure, utilizing both blowing and suction mechanisms simultaneously. Each air channel operates independently; the central channel is designated for blowing, making initial contact with the board to dislodge surface contaminants. On either side of this central channel, the air knives operate under negative pressure and are interconnected, primarily serving to suction off debris from the board's surface. The air intake is equipped with a high-efficiency HEPA filter, ensuring cleanliness and preventing secondary contamination of the board. Additionally, a cooling apparatus is installed at the air intake to maintain a consistent and appropriate outflow temperature.

Key Features:

- Magnetic Drive Wheel Mechanism: The machine's drive mechanism utilizes a non-contact magnetic drive, minimizing dust generation from contact.

- Ionized Air Anti-Static Bars: Two anti-static bars are installed at both the board entry and exit points of the equipment.

Product Advantages:

- Damage-Free Operation: The non-contact dust removal process does not induce any physical or chemical alterations, ensuring the product remains undamaged.

- No Consumables Required: Equipped with an imported fan, the machine is maintenance-free, devoid of wear-prone components, and ensures consistent pressure.

- Simplicity & Convenience: As air serves as the dust removal medium, there's no need for water or drying processes.

- Eco-friendly & Pollution-Free: The closed-loop system, utilizing internally circulated clean air as the medium, maintains the air balance in clean rooms and prevents secondary contamination.

- Customizable: The machine can be tailored to accommodate specific product dimensions, ensuring optimal processing width.

"Manufacturing Considerations for PCB Board Cleaning Methods"

Alcohol Cleaning:

- Pros: Easily accessible, effective for removing light oil and dirt, generally safe for most electronic components.

- Cons: May not be suitable for stubborn dirt, fire hazard, potential for static buildup.

Water Cleaning:

- Pros: Environmentally friendly, no use of organic solvents, suitable for general cleaning, generally safe for electronic components.

- Cons: Not suitable for all materials on circuit boards, requires thorough drying to prevent corrosion.

High-Pressure Gas Cleaning:

- Pros: Effective at removing dust and impurities, no liquid involved, does not cause corrosion.

- Cons: Sometimes requires high gas pressure, may not be suitable for sensitive components.

Brushing Methods Cleaning:

- Pros: Suitable for light dirt: Brushing methods are generally effective for light dirt and impurities. They can quickly and efficiently clean surfaces, making them useful for many general cleaning tasks.

- Cons: Potential for static buildup: It's important to note that brushing methods can sometimes generate static electric charges, which can pose problems for static-sensitive applications.

Adhesive Tackiness Cleaning Method:

Pros:

- Simplicity and Ease of Use: Adhesive tackiness is straightforward and user-friendly, requiring no complex training or special skills.

- Quick Cleaning: It can rapidly remove surface dust and dirt, making it suitable for situations that require fast cleaning.

Cons:

- Limited Cleaning Capability: Adhesive tackiness has limitations in terms of cleaning power, mainly suitable for surface cleaning and unable to remove deep-seated dirt or stains. While adhesive tackiness offers advantages in simplicity and speed, its application is constrained by its limited cleaning capability and is not suitable for tackling deep or stubborn dirt.

Direct Vacuuming Cleaning:

Pros:

- Efficient Removal of Dust and Impurities: Vacuum cleaners can efficiently remove surface dust, impurities, and particles, ensuring a rapid and thorough cleaning process.

Cons:

- Limited Accessibility: However, vacuum cleaning may not be suitable for hard-to-reach areas. For instance, in narrow crevices, deep-seated dirt, or complex internal structures, the suction power of a vacuum cleaner may not effectively reach, making cleaning challenging.

Introducing the WindBlade and Vacuum method:

This method offers several advantages compared to the previously mentioned cleaning methods:

1. Non-contact Cleaning: Wind wave cleaning doesn't involve physical contact with the PCB, reducing the risk of damaging delicate components.

2. Efficient Removal: It is effective at removing loose particles, dust, and debris from the PCB surface.

3. Quick Cleaning: Wind wave cleaning can be relatively fast, which is beneficial for high-volume production environments.

4. Reduced Contamination: Since it relies on airflow, there's less risk of introducing contaminants from brushes or cleaning materials.

Adaptability: It can be used for various types and sizes of PCBs, making it versatile for different applications.
