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 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…
ACW’s UV-Snap Cure Epoxies
Are you assembling temperature-sensitive components with shaded regions? If so, your choices of adhesives are limited. For your demanding applications, ACW offers UV-Snap Cure epoxies, adhesives developed for optoelectronics, electronics and semi-conductor packaging where the parts are opaque or have shaded areas and the components are temperature sensitive. UV-Snaps are one-component epoxies that are room Read More…
Low Temperature Dual Cure Epoxies (UV or heat)
ACW offers lines of Dual Cure epoxies that can be cured with either UV or heat to obtain high Tg epoxies with excellent reliability performance. All of the dual cure epoxies have room temperature pot lives (or working lives) of three days or more and shelf lives of several months when stored under appropriate conditions. Read More…
Low Outgas Adhesives
Several ACW products qualify as low outgas adhesives against the MIL-STD 883/5011, and Telcordia GR-1221 standards. If you are looking for a low outgas adhesive for your application, see the list of products on the Low Outgas page or contact us directly to discuss your application. ACW does not include solvents in any adhesive formulation, Read More…
Antimony-Free UV-Cure Epoxy Adhesives
Many UV-cured epoxy adhesives contain antimony as an integral component in the photo-catalyst. That can be a problem because antimony compounds are considered to be environmental hazards. Antimony-containing epoxies are tightly regulated in Japan, and one can expect to see increasing restrictions on them in upcoming years. Recent product development research at ACW has targeted Read More…
