Porous Ceramic Vacuum

Ceramic Vacuum Chuck is a kind of uniform solid or vacuum body produced by using nano-powder. A large number of connected or closed ceramic materials are generated in the material through high-temperature sintering.

The material is Al2O3 or SIC, which is widely used in Semiconductors and electronic devices.

In these applications, it can fix semiconductor wafers, glass substrate materials and other working objects by Vacuum Suction.

Compared with the characteristics of traditional suction cups for the single specification of workpieces, the regional suction function of Ceramic Vacuum suction cups helps to improve the smoothness of the production line and its performance, also avoid the traditional suction cups on the workpiece (especially the Thin Film material) scratches and suction marks.

Porous Ceramic Vacuum Work

In addition to being used to adsorb workpieces, Ceramic Vacuum Chucks can also be used in transmission-type air float modules. Even large pieces of glass substrates and other workpieces can be prevented from directly contacting the platform during transportation and transfer, avoiding.

Attachment of contaminants, stress, static electricity and damage to the glass substrate occurs. Moreover, the porous material can greatly reduce the gas flow, and can achieve the effect of uniform air pressure in the air cushion layer and can maintain a certain floating height.

The ceramic heating element is a safety and healthiest option for dry herb vaporizers, so every vaper is preferred to choose those vaporizers that carry ceramic heating element. The proponents believe that the heating element is the core of the vaporizer and primarily dictates the experience of the taste. Let's more specific, when a vaper burns tobacco, marijuana, or hemp during traditional smoking to release the active component, whatever it's nicotine, CBD, or THC, they inhale the smoke. We all know that's not good for health. Rather than burning, Vaporizer heats the liquid, wax or even dry herb to release a vapour, and a vaper inhales the vapour without any damage to their lungs or throat. And why the ceramic heating element is becoming the core part of the vaporizer? It's mainly because: 1. Ceramic ...

BAN combines  Aluminum Nitride with Boron Nitride , a hybrid machinable Aluminum Nitride ceramic with excellent thermal conductivity, high strength, and resistance to thermal shock. Innovacera provides BAN, and it has very similar properties to SHAPAL material. SHAPAL is a trademark of Tokuyama Corporation.   These ceramics are used in various industries, including electronics, semiconductor manufacturing, aerospace, automotive and medical. BAN ceramics have properties that make them suitable for applications such as  heat sinks , heater substrates, semiconductor processing components, and optical equipment.   Material Advantages : High mechanical strength. High thermal conductivity. Low thermal expansion. Low dielectric loss. Excellent electrical insulation. High corrosion resistance–non-wetted by molten metals. Excellent Machinabilit–BAN can be machined to high-precision complex shapes. It has excellent sealing ability to vacuum and hasn’t given off much gas. High-...
