In FPC, PCB, thick copper boards, and module assembly<\/strong>, have you encountered the following challenges?<\/p>\n<\/div>\n- Fine-line areas require high resolution while overall thickness must be reduced \u2014 but conventional materials cannot meet both needs<\/li>\n
- Excessive springback force in bending modules, affecting assembly accuracy<\/li>\n
- Difficulty achieving smooth planarization when filling thick copper height differences<\/li>\n<\/ul>\n<\/div>
Microcosm\u2019s liquid photo-sensitive PSPI provides a comprehensive solution to the challenges mentioned above.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
