  • Patent number: 7453260
    Abstract: The invention provides a method of testing a circuit on a substrate. Generally speaking, a substrate is located in a transfer chuck, a surface of a test chuck is moved into contact with a substrate, the substrate is secured to the test chuck, the test chuck is moved relative to the transfer chuck so that the substrate moves off the transfer chuck, terminals on the substrate are moved into contact with contacts to electrically connect the circuit through the terminals and the contacts to an electric tester, signals are relayed through the terminal and the contacts between the electric tester and the circuit, the terminals are disengaged from the contacts, and the substrate is removed from the test chuck.

  • Patent number: 5591290
    Abstract: The adhesive bonding strength of a pressure sensitive adhesive on a laminate is selectively modified by applying a discontinuous layer of a non-adhesive material to the pressure sensitive adhesive. Preferably, the laminate is a preformed, label stock, including a label or substrate having a pressure sensitive adhesive on one surface thereof and a release sheet overlying the adhesive. The label is first delaminated from the release sheet to expose the oppositely facing surface of the label and the release sheet. A discontinuous layer of the non-adhesive material is then printed on either the release sheet or the adhesive. The release sheet is relaminated back onto the label to form a modified laminate with new adhesive properties. When the label is then separated from the release layer, the non-adhesive material adheres to the pressure sensitive adhesive to reduce the exposed surface area of the adhesive.
