| Application: | This Ag ink product is a conductive high viscous ink based on single-crystal silver nanoparticles in an organic solvent, has been designed for LIFT (Laser Induced Forward Transfer) digital printing and laser sintering. The ink offers: • Uniform and reproducible donor layer with low drying speed • Stable accurate jetting in different types of laser systems, wide working window of jetting parameters • High speed printing (20-50kHz), allowing high throughput • Narrow patterning on plastic and glass substrates (line width ∼50 μm, height ∼0.5 μm, spacing ∼50 μm) • Laser sintering of LIFT printed pattern, providing good electrical properties Fit for: LIFT digital printing Additive electronic manufacturing Printed electronics: RFID, FPD, Sensors Laser induced forward transfer printing (LIFT) is a non-contact, nozzle-free, one step, direct laser writing process. LIFT can operate under atmospheric conditions, is compatible with low laser fluences, allows the printing of organic and inorganic materials as well as biological elements. The printing process can take place from both liquid and solid phases. It further has a high lateral resolution only defined by the laser spot size. It is a method compatible with inorganic semiconductor sensor fabrication, OLED fabrication and bio printing. |
