Digital Metal Coatings for Semiconductor Applications
Redefining Efficiency and Flexibility
Prexonics® is a Turnkey Solution for Digital Printing of Electronic Metal Coatings
Heraeus Printed Electronics redefines precision metallization in the semiconductor industry. With Prexonics®—our turnkey solution consist of particle-free metal inks, inkjet machines, and deep process know-how—you can implement selective, maskless metal coatings tailored to modern semiconductor manufacturing.
Precision and Efficiency in Electronic Coatings
- Our system features the specially formulated Prexonics® particle-free silver ink and the Prexonics® inkjet printing system, both engineered for effective 2.5D selective coating. This innovative approach allows for inkjet printing of precise pattern layouts, meeting the needs of miniaturization in electronics packaging.
Customized Thin Metallization Film
- Our digital printing technology enables the manufacturing of metallization films ranging from 150 nm to 5 μm, with conductivity levels at 20-50% of bulk silver.
- Central to our system is the Prexonics® Image Processor that accurately transforms CAD designs into precisely coated semiconductor components.
- The entire process, encompassing pre-treatment, inkjet printing, and sintering into a metallic silver film, is automated and fulfills the highest semiconductor industry standards.
