VINACNC - Expert in High-Precision Custom CNC Machining of Graphite Fixtures for Power Diode Packaging

In the semiconductor and electronics industries, the packaging of sensitive components like power diodes requires extremely high precision and heat resistance to ensure the quality of the final product. VINACNC is proud to offer a specialized custom graphite fixture manufacturing service, designed to meet the most stringent requirements of the power diode packaging 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 packaging process.

• Technical Properties:

  • Heat Resistance: Graphite can withstand temperatures of over 3000°C, making it ideal for high-temperature processes such as welding, 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 packaging process.

  • Smooth Surface: Graphite has a naturally smooth surface, which allows parts to be easily released from the fixture without damage.

     

• Applications: Graphite jigs and fixtures are widely used for:

  • Positioning and Holding Components: Securing power diodes or other semiconductor chips during encapsulation and packaging.

  • Packaging: Used to hold components in place during thermal processes that form the final package.

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 jig lifespan and allows for multiple reuses.

• Chemical Inertness: Graphite is an inert material that does not react with the packaging material, ensuring the quality and integrity 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 parts to be processed onto the fixture to ensure perfect positioning and secure holding.

Packaging and Storage Process

• Cleaning: The jig 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 jig in a dry, cool environment, away from heavy impacts, to maintain its best quality.
