VINACNC - Expert in High-Precision CNC Machining of Graphite Fixtures for TO Package Semiconductor

In the semiconductor and electronics industries, the assembly and packaging of sensitive components like the TO Package require extremely high precision and heat resistance. VINACNC is proud to offer a specialized EDM grade graphite fixture manufacturing service, designed to meet the most stringent requirements of the assembly, packaging, and Electrical Discharge Machining (EDM) processes for TO Package semiconductors.

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, which helps maintain the integrity of the components throughout the processing.

• Technical Properties:

  • EDM Grade: The selected graphite has high electrical conductivity and a fine grain structure, making it ideal for use as an electrode in EDM to create highly precise mould details.

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

  • High Precision: The fixtures are CNC machined to achieve precise tolerances, ensuring that the components are perfectly positioned and held securely throughout the assembly and machining processes.

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

  • EDM Machining: Used as electrodes to create complex mould cavities and features.

  • Semiconductor Packaging: Positioning and holding TO Package semiconductors during encapsulation and thermal processes.

  • Electronic Component Manufacturing: Used in sintering furnaces, vacuum furnaces, and other semiconductor production equipment.

     

Product Advantages

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

• 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 other materials, ensuring the quality and purity of the final product.

• Optimized Processes: The combination of precise machining capability and superior material properties helps to optimize the manufacturing process and minimize product defects.

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 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.
