  • Tool for drilling/routing of printed circuit board materials
    Patent number: 6830604
    Abstract: A dense cemented carbide product is described. The product is manufactured from WC with a grain size between 0.1 and 0.4 &mgr;m, fine grain size cobalt and ruthenium powders. The product is used in PCB machining operations where the addition of 10-25% Ru to the binder phase offers up to 25% wear resistant increases and up to 100% increase in chipping resistance in PCB routing compared to conventional materials (6% cobalt and 0.4 &mgr;m grain size).
    Type: Grant
    Filed: October 23, 2002
    Date of Patent: December 14, 2004
    Assignee: Sandvik AB
    Inventors: Alistair Grearson, John Aucote

  • Method of making ultrafine wc-co alloys
    Patent number: 6413293
    Abstract: The present invention relates to a method of making ultrafine WC—Co alloys from a well dispersed mixture of fine and non-agglomerated WC and Co powders, wherein the Co powders have a narrow grain size distribution wherein at least 80% of the grains have sizes in the interval x+0.2x with the interval of variation of 0.4x is not smaller than 0.1 um, and a carbon content of approximately the amount necessary to provide eta phase formation.
