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…
High Performance Nano-Imprint Lithography Resin
BD-400 is a high-performance photo nano-imprint lithography (P-NIL) resin. In P-NIL, a thin layer of resin is coated on a mold or substrate and cured with UV light to give a positive pattern with resolution at the 10’s to 100’s of nanometer level. BD-400 resin has excellent flow properties and can be spin-coated. Its films 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…
A1855-TX An Active Alignment Dual-Cure, Epoxy Only Adhesive with Deep UV Cure
Feb 10, 2020. Are you using a dual-cure adhesive for your active alignment applications? Dual-cure adhesives cure with both UV and heat so that one can fix the alignment with UV and then fully cure the adhesive with heat. With A1855-TX, we increased the depth of cure in the UV step to 750 microns. ACW’s Read More…
A Dual-Cure (UV or heat) Epoxy Adhesive that Blocks UV, Visible, and Near IR Light
Jan 22, 2020 ACW Dual-Cure epoxy adhesives are cured by either UV light or heat, and it sounds as if a light-blocking Dual-Cure epoxy might not be possible. But, that’s not the case. A1708-FT is a Dual-Cure epoxy adhesive that blocks almost all light, even into the near IR. If you are trying to cure Read More…
Optoelectronics Components that Live Forever?
ACW provides a variety of epoxy-only UV-cure and Dual-Cure (UV and heat) adhesives for use in optoelectronics applications. We were asked to demonstrate that one of our popular Dual Cure adhesives, A539-DM, could be used in the light path for 1,310 nm light under extreme conditions. Specifically, we were asked to show that A539-DM had 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…
