Abstract: A method of making a slotless electric motor wherein the active winding segments are adhesively affixed to a support surface or previously deposited active wire segments to form a self-supporting winding structure. The self-supporting structure is then secured in a magnetic structure of the slotless stator.

Abstract: An optical inspection system for inspecting faults on circuit boards like printed circuit boards and wire scribed circuit boards is disclosed. A video camera for receiving desired images of hole sites on a wire circuit board is provided. The camera converts each image to electrical video signals. A frame grabber converts electrical video signals to a plurality of pixels and stores information representing color element values contained in each of the pixels. A panel feature detector receives the color element values of the pixel that has to be analyzed and provides a wire indication when the color element value of the pixel corresponds to the wire feature. A fault detector circuit receives the wire indication from the panel feature detector corresponding to predetermined pixels associated with the hole site for determining faults on the circuit board.

Abstract: An apparatus and method for wire termination in wire scribed circuit boards is provided. The system includes a plurality of wires having termination areas, scribed on an insulating substrate. The top portion of the termination areas is then removed by a router to expose the wire with a flat surface. The exposed portion of the wire is then covered by a metal suitable for electrical connection bonding.

Abstract: An improved cutting apparatus and method used in a wire scribing device, said cutting apparatus having a cutter blade attached to a wiring head, and having a z-axis actuator for precisely controlling the movement of the cutter blade in the z-direction. A gauge height finder, attached to the wiring head determines a distance between the wiring head and the substrate, wherein the determined distance is used to control the z-axis actuator for lowering the cutter blade so as to precisely cut the conductor on the surface of the substrate. Furthermore, the cutting apparatus may include a cutter bracket attached to the wiring head, having a preloaded spring fixed thereto. Wherein this spring is preloaded to a preset force and wherein the spring is positioned above the cutter blade so that an upward force on the cutter blade is transmitted to the spring.

Abstract: A non-tacky, solid, adhesive composition comprising: (a) at least one film forming polymeric resin of number average molecular weight (Mn) of at least about 10,000 and having a hydroxyl, epoxide or unsaturated functionality greater than about 7, the polymeric resin being selected from the group of polyols consisting of polyesters, polyurethanes, phenoxies, epoxies and mixtures thereof; a plasticizer present in an amount which permits the activation without C-staging of the polymeric resin; (b) a curing agent which is capable of crosslinking and curing the polymeric resin to a C-stage, the curing agent being present in an amount sufficient to C-stage the polymeric resin. The adhesive composition can be activated without C-staging the polymeric resin, upon application of sufficient heat or ultrasonic energy for a time period less than one second.

Abstract: An apparatus for detecting breaks in wire while the wire is being scribed wherein the apparatus measures changes, in real time, in the scribing system's electrical characteristics. These characteristics can be changes in phase shift and capacitance variations caused by breaks in the wire as the wire is scribed onto a workpiece.
