With features of high temperature resistance, corrosion resistance, abrasion resistance and insulation, ceramic can work in many kinds of semiconductor production equipment with condition of high temperature, vacuum or corrosive gas for a long time. Made from high-purity alumina powder, processed by cold isostatic pressing, high temperature sintering and precision finishing, it could reach the dimension tolerance to ±0.001 mm, surface finish Ra 0.1, temperature resistance 1600℃. Here is the characteristics of alumina ceramic with different purity.Spray Granulation →ceramic powder → Forming → Blank Sintering → Rough grinding → CNC Machining → Fine Grinding → Dimension Inspection → Cleaning → PackingPlace of Origin: Hunan, China Material: Alumina Ceramic HS Code: 85471000 Supply Ability: 200 pcs per month Lead time: 3-4 weeks Package: Corrugated box, foam, carton Others: Customization service available1. How to do when the goods broken? 100% in time after-sales guaranteed! (Refund or Resent goods can be discussed based on the damaged quantity.) 2. Shipping EXW is normally; By sea or air can be selected. 3. Payment term Bank transfer Need more pls contact 4.Quick response service 8:30-17:30 within 10 min get response; We will get back to you within 2 hours when not in office; Sleeping time is saving energy For give you more effective feedback, pls leave message, we will get back to you when wake up!Prevent the particles that can generate from the bevel or angled edges and the back surface while wafers are transported or being in contact with End Effector / Handling Arm. For the guides, adopted a soft material that does not damage the wafer. Thinning is possible with ST.CERA's built-in vacuum channel technology that does not use adhesives. Possible to make mounting holes and to change the length and width of the base where the End Effector / Handling Arm is mounted on the robot. Mounting sensors, screws and brackets is available as an option. Designed to be used in atmosphere.
