Chemically etched evaporation / deposition masks are the workhorses of the stencil world.
They are the most cost effective and offer a fast turnaround.
Photofabrication have been producing masks /stencils for many years, the advantages of having these products chemically milled or photo etched is:
Evaporation masks become be-spattered with whatever material is being deposited. Cleaning the masks to remove this residue will wear the mask over time, rendering it useless. By plating Evaporation masks in either Gold or Rhodium, we can extend the life span of the masks.
Both Gold and Rhodium can withstand the acids used in post-deposition cleaning and therefore protect the substrate metal. Studies show that by using this method, the masks can withstand the cleaning process for up to 10 times longer than traditional masks.
For Masks and Stencils the manufacturing technique of choice is Chemical Milling, let us illustrate this in more detail:
