Recently, our company's automatic droplet large platform contact angle measuring instrument has successfully signed a contract with a large state-owned group company in Shanghai and has been successfully delivered for use. The group company currently operates and manages multiple production lines including 4.5-generation a-Si, 5th generation a-Si, 5.5-generation LTPS, 5.5-generation AM-OLED, 6th generation LTPS, and 6th generation AMOLED. Contact angle measuring instruments are the testing equipment used to monitor product quality during their production process. The contact angle of the large platform must fully consider the shape of the product and the limited space of the site, and design the product structure reasonably. The final contact angle of the large platform should not only meet the measurement requirements of LCD screen products, but also meet the spatial layout of the production site, and be more conducive to the convenient operation of personnel. Our contact angle measuring instrument is currently widely usedYuPCBSemiconductor packaging and testing, wafer (chip)LCDTheLEDRapid detection of contact angle and droplet angle in industries such as film, fiber materials, special coatings, petrochemicals, medical materials, etc.
