PCB Foil-Frames

Just got the first samples of the new foil frames made from PCB material. They look great and I am looking forward to test them.


The frame offers the following features:

  • Stiff frame for holding the hydrophobic foil
  • Temperature resistant for curing the foil coating on the frame
  • Grounded metallic layer on the bottom to reduce electrostatic charge on the foil
  • Contacts for the ITO glass grounding with special pin (top right) to measure dropplet movement
  • Easy to reproduce in open source
