VINACNC - Expert in High-Precision CNC Machining of Graphite Fixtures for TO-220 and TO-247 Diode Production

In the semiconductor industry, the production of sensitive electronic components like TO-220 and TO-247 diodes requires extremely high precision and heat resistance to ensure the quality of the final product. VINACNC is proud to offer a specialized graphite fixture manufacturing service, meticulously CNC machined to meet the most stringent requirements of the TO-220 and TO-247 diode production process.

Technical Specifications, Materials, and Applications

• Material: The products are crafted from high-purity graphite. This material stands out for its exceptional heat resistance, chemical corrosion resistance, and non-reactive nature with other materials, which helps maintain the integrity of the components during the production process.

• Technical Properties:

  • Heat Resistance: Graphite can withstand temperatures of over 3000°C, making it ideal for high-temperature processes such as soldering, sintering, or heat treatment.

  • High Precision: The fixtures are CNC machined to achieve precise tolerances, ensuring that the diodes are perfectly positioned and held securely throughout the production process.

  • Thermal Conductivity: Graphite has excellent thermal conductivity, which helps to dissipate heat efficiently during production, protecting sensitive components from overheating.

• Applications: Graphite fixtures are widely used for:

  • TO-220 and TO-247 Diode Production: Positioning and holding diodes during thermal processes like soldering and encapsulation.

  • Power Semiconductor Manufacturing: Used in sintering furnaces, vacuum furnaces, and other production equipment.

  • Assembly: Used as jigs for the precise assembly of electronic components.

Product Advantages

• High Precision: Thanks to CNC machining, our fixtures have absolute dimensional accuracy, facilitating high-precision mass production.

• Heat and Corrosion Resistance: The extremely high heat and corrosion resistance of graphite ensures a long fixture lifespan and allows for multiple reuses.

• Chemical Inertness: Graphite is an inert material that does not react with other materials, ensuring the quality and purity of the final product.

• Optimized Costs: The long lifespan and high production efficiency of our jigs help minimize investment and operational costs for our clients.

Post-Machining Product Inspection Process

1. Dimensional Inspection: We use digital calipers and other precision measuring tools to verify the dimensions of the graphite fixture against the technical drawings.

2. Surface Finish Inspection: We conduct visual inspections and use specialized measuring devices to ensure the surface meets the requirements and is free of cracks or defects.

3. Functional Test: A trial run is performed by fitting the components to be produced onto the fixture to ensure perfect positioning and secure holding.

Packaging and Storage Process

• Cleaning: The fixture is thoroughly cleaned to remove carbon dust and other impurities.

• Careful Packaging: The product is packed in a sturdy cardboard box or a wooden crate with foam to prevent impact and chipping during transport.

• Labeling and Instructions: The packaging is clearly labeled with product information, including the product code, dimensions, and usage/storage instructions.

• Storage: We recommend storing the fixture in a dry, cool environment, away from heavy impacts, to maintain its best quality.
