1. A method of microforming an array of microstructures comprising:
- advancing a punch having an array of protrusions towards a sheet of material disposed between the punch and a die, each protrusion shaped to deform the sheet of material into a corresponding microstructure;
providing a holder for holding the sheet of material in place; and
punching the sheet of material with the protrusions on the punch to form the array of microstructures on the sheet of material.

Abstract
A method of micro forming an array of microstructures comprising: advancing a punch having an array of protrusions (620) towards a sheet of material (640) disposed between the punch (620) and a die (630), each protrusion (625) shaped to deform the sheet of material (640) into a corresponding microstructure; providing a holder for holding the sheet of material (640) in place; and punching the sheet of material (640) with the protrusions on the punch (620) to form the array of microstructures on the sheet of material (640).

19. An apparatus for microforming an array of microstructures comprising:
-
a punch having an array of protrusions; a die; and a holder for holding a sheet of material in place during microforming, wherein each protrusion is shaped to deform the sheet of material into a corresponding microstructure; and
wherein the sheet of material is punched with the array of protrusions to form the array of microstructures. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
