COB/COG/COF
With the rapid development of smart phones, people have higher and higher requirements for mobile phone camera pixels. Nowadays, the mobile phone camera module pixels manufactured by traditional CSP packaging technology cannot meet people's needs, while the mobile phone camera module manufactured by COB/COG/COF packaging technology has been widely used in the current mobile phone with 10 million pixels. But the yield of its manufacturing due to its process characteristics is often only about 85%, and the mobile phone yield is not high mainly because the centrifugal cleaning machine and ultrasonic cleaning can not do high cleanliness cleaning holder and Pad surface pollutants, resulting in holder and IR adhesion is not high and bonding poor problem, After plasma treatment, the organic pollutants and activated substrate on the holder can be ultra-clean removed, so that the adhesion between the holder and IR can be increased by 2-3 times. Also, the oxide on the Pad surface can be removed and the surface coarser, which greatly improves the success rate of banding.
