Alumina Ceramics:
Semiconductor products are required to be very clean and pollution-free. In the production of semiconductor products, the requirements for the environment are very high, generally in strict dust-free workshops, and production personnel must wear anti-static clothing. Semiconductor products are very delicate products. Some products are ultra-thin, only a few tenths of a millimeter, and some are even thinner, so they are required to be handled with care. During processing and various treatments, there are high requirements for various clamping tools, clamping tools and utensils that come into Ceramic Part contact with Alumina Ceramic Insulators semiconductor parts, mainly to not contaminate the semiconductor parts, and these fixtures must also be able to withstand various acids. The test of treatment, alkali treatment and heat treatment, so as to be durable.
Origin of the name of the ceramic manipulator: The ceramic manipulator is used to grab and clamp semiconductor parts, acting like a hand. It is designed as a flat arm and palm, so they are called mechanical arms.
The structure and function of the ceramic manipulator: There are air holes and ventilation slots in the manipulator. When the air is pumped, a vacuum can be formed, so as to absorb the semiconductor parts, so as to achieve light contact, no pinching, and no damage to the semiconductor parts sheet.
Advantages of clamping semiconductor parts with ceramic arms compared to metal arms:
1. Ceramic robotic arms are more resistant to acid Alumina Ceramic Bar corrosion and alkali corrosion than metal arms. Longer service life during various semiconductor treatments;
2. The ceramic robotic arm is not easy to react with other substances, and will not leave polluted fine particles and charged charges on the contacted objects, and will not generate metal ions and contaminate semiconductor parts;
3. When the semiconductor is heat treated, the ceramic manipulator is less deformed by heat, which reduces the deformation of the semiconductor parts during heat treatment.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
