Vincent J. Pellechia has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Low temperature and low cost assembly process for nonlinear resistors
    Patent number: 4189083
    Abstract: A low cost two step process for attaching conductive leads and heat dissipating elements and for encapsulating a ceramic non-linear resistor pellet is described. Low temperature soldering techniques are utilized to assemble the device. Low temperature soldering is made feasible by the treatment of the attaching surfaces of the pellet with a dilute solution of acid for reducing the oxide surface to a pure metal in preparation for soldering.
    Type: Grant

  • Low cost assembly processes for non-linear resistors and ceramic capacitors
    Patent number: 4189084
    Abstract: A brazing operation, using a silver-copper alloy preform in a temperature range of from 800.degree. C. to 1100.degree. C., is employed to attach either radial or axial conductive leads to ceramic non-linear resistors or capacitors, thereby eliminating the necessity of titanium-silver vacuum deposition or conductive cermet application prior to lead attachment. Glass encapsulation may be accomplished simultaneous with the brazing operation to further reduce cost.
