Range of Viscosities of Dual-Cure Adhesives for Active Alignment

Active alignment of optical components in cameras and sensor modules has become common practice.  In this method, lenses and detectors are mated with an adhesive in place, their alignment is actively controlled by computer, and the adhesive is set by UV irradiation.  By design, most of the assemblies constructed by this method contain some opaque Read More…

BD-400: Automotive Tough P-NIL Resin

Photo-Nanoimprint Lithography (P-NIL or UV-NIL) is a versatile technique for low-cost nanoscale device fabrication with a wide range of applications.  As automobiles with increasing numbers of detectors evolve, opportunities for P-NIL fabricated lenses will increase.  But, for the automotive industry, P-NIL materials must survive extreme stress conditions required to demonstrate automobile efficacy.  BD-400, ACW’s premier Read More…

Nanoimprint Lithography Resins

UV or photo Nano-Imprint Lithography (UV-NIL or P-NIL) is a versatile technique for low-cost nanoscale device fabrication. The precise, direct patterning and repeatable replication of complex three-dimensional nanoscale patterns (submicron, 10’s of nanometers) in a single step make the NIL technique compelling in comparison to other expensive techniques such as e-beam or helium ion beam Read More…

Adding Spacer Beads in Your Adhesive for Precise Bondline Widths? ACW Can Help.

Feb 11, 2020.  A common method for obtaining precise bondline widths is to add spacer beads to an adhesive.  Unfortunately, if you are doing that yourself, you likely have not had many pleasant experiences.  ACW can eliminate the pain by adding the spacers for you. Spacer beads are a great way to give reproducible, precise Read More…

Flowing and Non-Flowing Thermally Conductive Epoxies

Thermally conductive epoxy adhesives are important in semiconductor packaging applications because they can provide both bonding strength and thermal conduction from the device to a thermal sink.  Thermally conductive epoxies are either electrically conductive, containing a metal filler, or electrically insulating, containing a ceramic filler. ACW offers thermally conductive electrically insulating dual cure epoxy adhesives Read More…
