Patent number: 6112407Abstract: A circuit board fabrication method and system is disclosed in which circuit boards are fabricated by adhesively applying circuit conductive traces to a circuit board substrate and subsequently affixing the arrangement of the circuit traces on the substrate by encapsulating and embedding the circuit traces within a circuit board covering material that becomes flowable and adhesive when subjected to heat and pressure. In one embodiment, the circuit traces are created and applied to circuit board substrate areas by a punch and die assembly. A sheet of circuit trace material is provided between plates of the apparatus wherein the plates have matching circuit trace shaped cut-outs. Punch elements having a mating circuit trace shape are slidable within the cut-outs wherein a circuit trace is punched from the circuit trace material when the punch elements slide between the plates. After a circuit trace is punched, the punch elements then stamp the circuit trace to the substrate.Type: GrantFiled: November 26, 1996Date of Patent: September 5, 2000Assignee: Circuitronics, Inc.Inventor: George R.

Patent number: 5738268Abstract: A process for preparing tubular coupons formed of a pair of tube lengths butt-welded together with a full depth circumferential weld includes partially diagonally cutting the coupon sample through its transverse dimension so as to leave a thin bending strip along one wall of the coupon about which the coupon is bent for inspection of the internal surface of the weld area. Two procedures are described, both of which leave the interior surface of the weld exposed adjacent the diagonal cutting line through the coupon. The procedure facilitates bending open the cut coupon for internal inspection of the weld area. A jig fixture for holding the coupon during cutting by a band saw blade is described.Type: GrantFiled: March 28, 1996Date of Patent: April 14, 1998Assignee: TRI Tool Inc.Inventors: Jerald VanderPol, Clement Tremblay
