| titleOfInvention | A kind of LDI photosensitive dry film and preparation method thereof |
| abstract | The invention provides an LDI photosensitive dry film and a preparation method thereof, belonging to the technical field of photosensitive dry film, and comprising the following steps: S1. After heating and mixing, stirring and reacting to obtain the reacted resin; S2. The reacted resin, photoinitiator, methyl bisphenol A acrylic resin, nonylphenol acrylic resin, photosensitive monomer, photosensitive resin auxiliary, LCV pigment , 1,2'-bis(2-chlorophenyl)-tetraphenylbiimidazole is stirred at a low speed, and mixed evenly to obtain the LDI photosensitive composition; S3. Coating film: the LDI photosensitive composition is evenly coated on the extrusion film head with an extrusion film head. On the clean PET film, a layer of PE protective film is laminated on it after being baked in a tunnel oven to obtain an LDI photosensitive dry film. The LDI photosensitive dry film of the invention can reduce the cost, increase the production capacity, is more convenient to use, can make finer circuit boards, and has wider application areas. |
