With the expansion of electronic products in the daily life application, electronic products are important components of the semiconductor industry. The use of rubber sealing elements in electronic products is even more indispensable. For example: cameras, mobile phones, smart watches, tablets, game consoles, aerial cameras, and so on. The automation equipment technology is developed, and the products have entered the "automation" high demand. For example, the use of vacuum suction cups to transport the transfer TFT glass substrate, semiconductor manufacturing has special requirements for product cleaning and chemical resistance, and the vacuum chuck surface impedance value is divided into conductive, antistatic (ESD), low imprint, Yuansheng Can be adjusted according to customer needs to meet customer needs.
