CY-800 CNC Dicing and Cutting Machine

Product Overview

The CY-800 CNC Dicing and Cutting Machine is a computer-controlled 3D continuous cutting system, programmed via software to manage the cutting process. It is primarily designed for dicing and slotting materials such as crystals, ceramics, glass, and various thin materials. It can also cut other materials, including crystals, ceramics, glass, ores, and metals. The machine supports samples with diameters up to 200mm and cutting depths of up to 10mm.

The CY-800 employs a stepper motor drive, achieving a cutting accuracy of up to 0.02mm. Its sample stage features a vacuum suction cup that can rotate 360°. The spindle speed is adjustable and controlled steplessly, enabling fast cutting, smooth operation, and precise feed control. During operation, an external water circulation system can be connected to cool the sample, preventing damage or structural changes caused by heat generated during cutting. Depending on the material, different cutting blades can be selected. Additionally, the sample cutting table is equipped with a waterproof cover to prevent water splashes.

This machine is an ideal precision cutting solution for laboratories and production facilities processing large crystal wafers.

Technical Parameters

Main components：

Application Fields

Semiconductor Industry: Used for dicing semiconductor wafers into individual chips from larger wafers.

Solar Panels: Cutting solar panels to meet different size requirements.

Electronic Component Manufacturing: For cutting various small electronic components, such as sensors and LEDs.

Optical Component Processing: Precision cutting of optical materials like laser glass and lenses.

Application Example: "Dicing a 6-Inch Wafer Using a Dicing and Cutting Machine"

Process Steps

1. Wafer Preparation

Cleaning: Thoroughly clean the 6-inch wafer before cutting to remove dust, impurities, and any substances that may affect the cutting quality. Common cleaning methods include ultrasonic cleaning and chemical cleaning.

Inspection: Check the wafer for visible defects (e.g., cracks or scratches) to ensure the material quality meets cutting requirements.

2. Positioning and Installation

Wafer Installation: Place the cleaned wafer on the dicing machine’s cutting table, typically secured using a vacuum suction system to prevent movement during cutting.

Precise Alignment: Use an automatic alignment system or laser positioning device to ensure accurate alignment of the wafer. Proper alignment is crucial to ensure that chip positions match the design specifications during the cutting process.

3. Cutting Plan Design

Path Setting: Use computer-aided design (CAD) software or the dicing machine’s control system to plan the cutting path. The path is optimized based on the wafer design requirements, including chip size, spacing, and cutting sequence.

Parameter Configuration: Set cutting parameters such as cutting speed, depth, blade type, and coolant flow rate to ensure quality and efficiency.

4. Blade Selection and Installation

Blade Selection: Choose a suitable blade, such as a diamond blade or another hard-material blade. Diamond blades are often used for semiconductor wafers due to their high hardness, ensuring cutting precision and quality.

Blade Installation: Mount the cutting blade onto the dicing machine’s spindle, ensuring it is securely installed for high-speed rotation.

5. Cutting Process

Start Cutting: Once all settings are complete, start the dicing machine. The blade rotates at the preset speed and cuts along the predefined path.

Depth Control: Adjust the blade’s cutting depth based on the wafer thickness, typically 50%-70% of the wafer’s thickness, to ensure smooth cutting.

Cooling System: Use coolant (usually water or water-based coolant) to spray onto the cutting area during the process. This reduces heat generation and minimizes blade wear.

6. Post-Cutting Processing

Quality Inspection: Perform an initial inspection of the diced chips to ensure cutting quality. Check for chip dimensions, edge smoothness, cracks, and burrs.

Cleaning: Clean the wafer and chips again to remove debris and coolant residues from the cutting process.

Drying: Dry the cleaned wafer and chips to avoid moisture affecting subsequent processes.

7. Follow-Up Processes (Optional)

Packaging and Storage: Diced chips are typically packaged to prevent damage or contamination. Packaging can range from encapsulated chips to bare die packaging.

Testing and Sorting: Some chips may undergo testing to ensure their electrical performance meets requirements. Chips that fail testing are sorted and discarded.

8. Quality Control and Recordkeeping

Quality Inspection: Conduct comprehensive quality checks on diced chips, including dimensional accuracy, surface quality, and electrical performance.

Documentation and Traceability: Record cutting parameters, quality control data, and product inspection results for future traceability and quality management.

Key Considerations During the Cutting Process

Cutting Speed and Pressure: Avoid excessive cutting speed to prevent surface or edge cracks on the wafer. Control the cutting pressure carefully to ensure smooth cutting.

Coolant Flow Rate: Maintain sufficient coolant flow to reduce heat generation and prevent thermal damage to the wafer.

Blade Wear: Regularly inspect blade wear and replace blades as needed to maintain cutting precision and efficiency.

Chip Spacing: Precisely control the spacing between chips during cutting. Excessive spacing wastes wafer material, while insufficient spacing may lead to weak connections between chips.
