The new VLIS process (short for Volume Laser Induced Structuring) enables high density through holes in glass for advanced packaging solutions. For various applications, tens of thousands of holes per wafer are deposited which then could be metallized to produce the required conductivity. Previous methods for manufacturing were slow, associated with high reject rates and difficult to match to the metallization process.
Together, Plan Optik AG and 4 Jet Group have more than 60 years of experience in processing glass. With an additional 30 years of experience in the field of laser technology and laser processing, this cooperation bundles an immense know-how into a unique process chain for the highly productive production of metallized through holes in glass.
As a technology leader, Plan Optik AG produces structured wafers made of glass, glass-silicon or quartz which are used as active elements for numerous applications in microsystems technology in sectors such as consumer electronics, automotive, aerospace, chemicals and pharmaceuticals.
The 4JET Group delivers solutions for the surface technology of the future. Customers include all of the world’s leading tire manufacturers, numerous automotive suppliers and OEMs, as well as the largest manufacturers of flat glass and thin-film photovoltaic cells.
