We provide the Desktop R2P NanoImprinter as an R&D tool with starter packages of materials. We do not provide the Desktop R2P NanoImprinter as a regular production process or machine with guaranteed results and client acceptance schemes for various NIL applications. That involves a completely different business setup on which we are happy to elaborate […]
Linear Gratings – period:>100nm, height:100nm; Holes on Square Lattice – period:>100nm, height:100nm; Hexagonal pillar array – Period（Gap+Diameter）: 230μm, Diameter: 200μm, Height: 30μm; Pillars on Square Lattice – period:>100nm, height:100nm. Can the Desktop R2P NanoImprinter reach the requirement? Tests and trials are always recommended to find the right parameters and materials.
You can make it yourself or get prepress material or finished prepress from Stensborg. We have years of experience.
Which solvent could we use to remove uncured DM 56 and X166b resist? We just need a solvent in which the resists are soluble. Would Acetone or EBR solvent (PGMEA) work?
We have successfully used IPA, and Acetone should also work but that is of course depending on what base substrate the none-cured resin is applied to and your potential application work afterward. For our industrial roll-to-roll machines we also used industrial-grade environmentally-friendly UV cleaner on metal and rubber parts that is in contact with non-cured […]
Here are some things we can recommend to you: Avoid resin on the soft impression layer in the first place. We highly recommend mounting the imprint plate on top of the protective foil that acts as a sacrificial foil. Using a sacrificial foil this way is the most straightforward, and reduced the risk of damaging […]
Is the print plate of the starter kit PDMS, or other Polymer? Is it possible to design printing plates according to customer requirements?”
The chemistry we provide makes it easy to design imprinting templates according to the customers’ own requirements. The imprinting template: The imprinting template comprises a pre-defined surface relief structure, the surface relief structure being arranged to be imprinted on the sample substrate. The imprinting template can take any suitable form. However, in general, it should […]
What are the removal methods of residual glue after embossing? Can residual glue be removed cleanly when you are done with the imprinting template?
If your imprint template is on a sacrificial foil (included with our Desktop R2P NanoImprinter), and you are using the double-sided adhesive tape – the foil itself can be removed from the cylinder, as it is the easiest method to manage without any risk that cleaning chemistry is exposed to the imprint cylinder. If your […]
How do you ensure the stability of the template and that it doesn’t slip when it is only secured with tape?
Typically using the tape on the edges works fine. For additional stability, a double-sided adhesive is recommended, but as the mechanical forces tend to diffuse, not much strain is introduced on smaller pieces of tape. When mounting the imprint template using tape on the edge, you have to place the tape under tension, so there […]
The substrate would be fixed with either tape or not at all, friction could be sufficient to keep the substrate fixed, the latter would be substrate-dependent.
Is it important to have a bearer stripe? I do not have bearer stripes in the right dimensions for my application.
When imprinting on thick and narrow substrates, for instance, a glass slide: it is necessary to have at least an improvised quasi-bearer stripe, if you don’t have long enough pieces to make such. This could be done by starting off with a double-sided adhesive on a larger plate that would fit on the machine, akin […]
