Technological breakthrough
★ Ultra low metal impurities: Na/K content<1ppm, meeting G5 electronic grade standards
★ Low temperature polymerization characteristics: reaction can be initiated at 80 ℃, compatible with flexible substrate technology
★ Dielectric strengthening: After curing, the dielectric constant is less than 2.8 (1MHz), which is better than traditional SiO2
Solution
Chip packaging:
As a precursor of Low-k dielectric layer, reducing RC delay
Enhance the step coverage of 3D packaged TSV structures
Electronic adhesive:
Modified epoxy resin to achieve a thermal conductivity of 1.5W/mK
Curing shrinkage rate<0.3%, reducing packaging stress
