Photosensitive Polyimide Coating System Photosensitive Polyimide Coating System - Ultrasonic Coating - Cheersonic Photosensitive polyimide is a kind of organic material with both imide ring and photosensitive gene on the polymer chain, which has excellent thermal stability, good mechanical properties, chemical and photosensitivity. Photosensitive polyimide has two main functions in the field of electronics: photoresist and electronic packaging. Adding sensitizers, stabilizers, etc. to photosensitive polyimide can obtain "polyimide [...]

Applications of Photosensitive Polyimide Photosensitive polyimide (PSPI) is a type of polymer material that has both heat resistance and photosensitive properties. It is a very important semiconductor material and a very stuck material. Due to its electrical insulating properties, it protects semiconductor circuits from physical and chemical conditions. Photosensitive polyimide mainly plays two major roles in the electronic field: photoresist and electronic packaging. 1. As photoresist As a [...]

Classification of Photosensitive Polyimide Classification of Photosensitive Polyimide - Photoresist & Polyimide Films Coating Systems - Cheersonic According to the different photolithography patterns, photosensitive polyimide (PSPI) can be divided into positive photosensitive polyimide (p-PSPI) and negative photosensitive polyimide (n-PSPI). Positive PSPI is that the ultraviolet irradiation area dissolves in the developer, and negative PSPI is that the irradiation area is cross-linked and solidified and no longer dissolves in [...]

Difficulties of Photosensitive Polyimide The production of PSPI photoresist is in the middle of the industrial chain structure. It is an ideal insulating material in the field of electronics and microelectronics. It is one of the most important electronic chemical materials in the fields of optoelectronics and microelectronics such as display panels, LED packaging, semiconductors, etc. It is widely used as interlayer insulation, surface passivation, stress buffering, and [...]

Application of Thermally Conductive Insulating PI Film In the era of highly thin, multifunctional and integrated electronic devices, it will inevitably lead to heat accumulation inside the composite material, seriously affecting the stable operation and service life of the equipment. How to achieve fast and efficient thermal conductivity and heat dissipation of dielectric materials has become a key issue affecting the development of electronic equipment. The low intrinsic [...]
