SiC-Coated Graphite Jigs

Chip manufacturing complexity continues to increase due to the rapid advancement of  semiconductor industry, and their demands for process accuracy and stability have reached a very high level. In order to ensure the accuracy and consistency of final device parameters, Semicorex SiC-coated graphite jigs can be used to provide stable support for chip manufacturing and enable precise chip mounting and localization.

Advantages of Semicorex SiC-coated graphite jigs

1. Excellent material properties

Crafted from carefully selected premium materials, Semicorex SiC-coated graphite jigs boast exceptional high-temperature resistance and chemical corrosion resistance, which enables them to adapt to the demanding complex operating conditions encountered in packaging and testing processes.

Moreover, Semicorex SiC-coated graphite jigs deliver superior thermal conductivity and their rapid and uniform heat conduction can significantly eliminate the quality inconsistencies of finished devices caused by uneven temperature distribution, making them fully satisfying the extreme heat dissipation requirements of high-power device packaging.

2. Precise machining accuracy

Semicorex SiC-coated graphite jigs are carefully fabricated through advanced CNC machining, which can ensure precise cavity dimensions and consistent spacing. With stringent control over dimensional tolerances, Semicorex SiC-coated graphite jigs can ensure precise alignment of chips and packaging materials. Besides, Semicorex SiC-coated graphite jigs can overcome the the dimensional changes caused by the temperature fluctuations thanks to their outstanding thermal shock resistance, thus ensuring sustained precision and stability throughout chip processing.

In addition, after refined grinding and specific surface treatment, Semicorex SiC-coated graphite jigs present superior surface flatness. This ensures perfect contact between chips and jigs, minimizes friction and contact resistance, and ultimately improves the accuracy of packaging and testing.

3. Stringent cleanliness control

Semicorex upholds uncompromising standards for cleanliness right from material sourcing. With high-purity isostatic graphite substrates and fully dense SiC coatings, particle generation and contamination are drastically reduced. The dense protective SiC coatings can withstand corrosive media in semiconductor packaging and testing, effectively avoiding impurities and ultimately boosting the yield of chip production.

Benefiting from the above excellent advantages, Semicorex SiC-coated graphite jigs are well-suited for the various packaging and testing applications in the semiconductor field. Semicorex offers high-end customization services and supports OEM manufacturing based on customers’ designs to achieve seamless matching with the targeted applications.
