Edward F. Handford 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).

  • Patent number: 5543584
    Abstract: The present invention relates generally to a new method of repairing electrical lines, and more particularly to repairing electrical lines having an opening at the module level with devices in place. Various methods and processes are used to repair this open or defective portion in an electrical conductor line. It could be repaired by securing a jumper wire or nugget across the open or the repair could be made by a deposition process, which includes but is not limited to filling the opening with a solder type material or inserting a solder coated electrical wire and heating the solder and allowing the solder to melt and repair the open. One of the attributes of this invention is the ability to repair on a substrate or module on which active components such as chips, and passive components such as pins, capacitors, etc. have been attached. The invention also allows repair of fine line patterns which are normally not repairable by conventional techniques.

  • Patent number: 5288007
    Abstract: The present invention relates generally to apparatus and methods for making simultaneous electrical connections, and more particularly to making these electrical connections simultaneously using a new bond tip configuration. Various methods and processes are being disclosed to simultaneously make electrical connections between electrical conductor lines or pads. The electrical connection is made by placing an electrically conductive wire across a pair of electrical lines or pads that have to be electrically connected and then by using a special tip, both ends of the electrically conductive wire are simultaneously secured to the two electrically conductive lines or pads.
