Very High Refractive Index Resins for P-NIL Applications

ACW introduces a new line of LuxNIL® very high RI resins for P-NIL VR/AR/MR applications or other thin coatings.  These resins are hybrid organic/inorganic, low viscosity formulations containing PGMEA.  They are suitable for spin coating, gravure coating, or ink-jetting to give thicknesses of 100 nm to 3 microns after evaporation of the PGMEA.  The cured Read More…

Adhesives that Survive Solder Reflow

Those working with semiconductors are familiar with solder reflow conditions.  A PCB containing solder and flux is heated to ca. 150 °C (pre-heat), held there for 1-2 minutes (soak), heated to ca. 260 °C, then cooled. As devices are miniaturized, physical clamps holding and aligning components are increasingly replaced with adhesives.  But solder reflow conditions Read More…

Addison Clear Wave Has Updated Its Photo Nanoimprint Lithography (P-NIL) Resins Brochures

ACW has updated its brochures for resins for P-NIL applications.  The updated brochures include the results of environmental and thermal shock stress tests on resins coated on glass.  The environmental stress tests were 1000 hours at 85 °C and 85% relative humidity.  The thermal shock tests were 1000 cycles of 150 °C for 30 minutes Read More…

High Refractive Index (RI) Resins for Bright Diffractive Optical Elements (DOE)

High brightness diffractive optical elements (DOE) employ high refractive index (RI) materials.  A cost-effective approach to these DOEs is to use a high RI resin that can be processed rapidly by photo nano-imprint lithography (P-NIL) methods.  ACW has been a leader in developing resins for P-NIL since the methodology was referred to as 2P (for Read More…

Non-Yellowing P-NIL Resin for Diffractive Optical Element (DOE)

Photo nanoimprint lithography (P-NIL) processes are cost effective methods for production of diffractive optical elements (DOE) used in holographic displays.  A limiting factor for this method is the environmental stability of the P-NIL resin.  If the P-NIL material yellows considerably with aging, the DOE with have limited utility.  In automotive applications, for example, the DOE Read More…
