  • Patent number: 6642477
    Abstract: A method of forming a through-hole which is counter-tapered relative to a drilling laser involves directing, along an incidence axis and onto an impingement location on a first surface of a material, a laser beam of sufficient energy to ablate the material, the incidence axis being offset from a normal to the first surface at the impingement location. The material and the laser beam are then relatively rotated, for at least 360°, such that a through-hole having a larger exit opening than entrance opening is formed.

  • Patent number: 6624885
    Abstract: A method for inspecting small holes in a material is disclosed. The method comprises directing a light source through the holes in the material, and then focusing the light passing through the material onto a CCD detector. The focusing techniques allow for a reduction in the size of the image which must be inspected, thereby increasing sample throughput, while still allowing for detailed inspection of the hole number and quality. Methods of producing an aerosolization container and device comprising membranes which pass such an inspection are also provided.
