VINACNC - Expert in High-Precision CNC Machining of Graphite Molds for Power Semiconductors

In the power semiconductor and electronics industries, manufacturing complex components requires molds with extremely high precision, heat resistance, and chemical corrosion resistance. VINACNC is proud to offer a specialized CNC machined graphite mold manufacturing service, designed to meet the most stringent requirements of the production process for power semiconductor devices.

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 throughout the manufacturing 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 molds are CNC machined to achieve precise tolerances, ensuring that the components are perfectly positioned and shaped throughout the production process.

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

• Applications: Graphite molds are widely used for:

  • Semiconductor Packaging: Shaping the outer shell and encapsulating power semiconductor chips like IGBTs and diodes.

  • Sintering: Used as a mold for sintering semiconductor materials at high temperatures.

  • Thermal Processing: Used as a fixture or boat for high-temperature thermal processes.

Product Advantages

• High Precision: Thanks to CNC machining, our molds 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 mold 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 molds 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 mold 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 processing a sample to evaluate the quality of the resulting product and the mold's performance.

Packaging and Storage Process

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