Coating Of Circuit Board Flux Coating Of Circuit Board Flux - Flux Spray - Cheersonic The flux must be applied to the underside of the printed board in the most efficient and economical way possible. The flux coating should be uniform and completely cover the soldered parts. If the flux is used in excess, it will not only drip onto the preheater and cause a fire hazard, but also be [...]

Semiconductor Photoresist Semiconductor Photoresist - Lithography Coating - Cheersonic Photoresist, also known as photoresist, refers to a resist etching film material whose solubility changes through irradiation or radiation of ultraviolet light, electron beam, ion beam, X-ray, etc., mainly composed of photoresist resin, It is composed of sensitizer (photoinitiator + photosensitizer + photoacid generator), monomer, solvent and other auxiliaries. Due to many application scenarios, photoresists for different purposes have different performance [...]

Semiconductor Wafer Manufacturing Process Semiconductor Wafer Manufacturing Process - Semiconductor Coatings - Cheersonic The manufacturing process of semiconductor silicon wafers is complex, and single crystal pulling is the key link The upstream of semiconductor wafers is semiconductor-grade polysilicon material, and the downstream is semiconductor products. Silicon is the main form of silicon dioxide in nature, and it is chemically reduced to generate polysilicon material, and then purified. The purity requirements [...]

Semiconductor Silicon Wafer Industry Barriers Semiconductor Silicon Wafer Industry Barriers - Photoresist Spray - Cheersonic The semiconductor wafer industry has high barriers, and the first-mover advantage and scale effect are prominent Technical barriers: The technical parameters of semiconductor silicon wafers are highly required, and each process link needs to be accumulated for a long time.
