Frequently Asked Questions
1. What are the main benefits of using antistatic ceramic components?
Antistatic ceramics feature a controlled resistance value (typically 10^5 to 10^9 ohms) throughout the homogeneous material rather than just a surface coating. This ensures reliable and permanent electrostatic discharge (ESD) protection, preventing damage to sensitive components like semiconductor wafers and LCD panels during handling.
2. Can the large size porous ceramic vacuum modules be customized for larger systems?
Yes. While the maximum size of a single ceramic piece is 500*500mm, they can be precisely spliced together on base materials like granite or aluminum to accommodate large panel sizes of 2000*2000mm or more.
3. How does the non-contact transmission air floating plate prevent contamination?
The air floating plate is made of high-temperature sintered porous ceramics with high strength and wear resistance. Because it uses positive air pressure to suspend and transfer products without physical contact, it does not generate dust particles, making it ideal for cleanroom environments.
4. What makes the Chuck Table Wafer Cutting Disc suitable for high-precision dicing?
The dicing tray features a high-precision surface grinding flatness of less than 5µm and high adsorption uniformity. Combined with static-dissipating porous ceramics, it ensures secure holding and clean cuts without electrostatic buildup during the wafer cutting process.
5. What is the maximum temperature limit for the heated vacuum chuck?
The heated vacuum chuck is designed to handle simultaneous heating and vacuum adsorption, with a maximum operating temperature of up to 150 degrees Celsius.
6. What applications are porous ceramic tubes designed for?
Porous ceramic tubes are specifically designed for continuous Roll-to-Roll manufacturing processes, including optical films, thin-film LCD processes, and micro-nano imprinting, offering both positive pressure air flotation and negative pressure adsorption.
