Working on NOCC patterns made by Ali Aslan Demir (AAD). Based on previous experience, I have a feeling that the patterns did not transfer that well during curing due to the UV glue being too viscous and not getting through the entire stencil via capillary forces. Three tactics to combat this have been suggested:
- Use less viscous glue. At the moment I am using NOA73, but DKD has recently purchased NOA89, which is the least viscous of the glues that they have. Using less viscous glue might help with glue getting through all of the small patterns and spreading across the entire surface of the stencil.
- Let stencils sit for longer to let capillary forces do their job properly instead of curing too quickly.
- Covering the stencil with aluminum when wicking (letting glue get through due to capillary forces) so that the glue does not cure under normal light too quickly. Since the layer of the glue is very thin, normal light might affect it and not let it get through the entire area.
In today's experiments, I will be trying to keep every step of the protocol the same except for the glue. I will use the new NOA89 glue and see if it works better than NOA73.
