    摘要: A method is provided for applying a fluid to a plurality of locations on a non-planar substrate. The apparatus used includes a movable base and an array of pins connected to the base. Each pin has a distal end which is vertically movable with respect to the base independently of the rest of the array of pins. Each distal end is adapted to transfer fluid to a location on the substrate by having a greater affinity for the fluid than the fluid has for itself and a lesser affinity for the fluid than the fluid has for the substrate. Accordingly, the distal ends may be dipped in the fluid and moved into contact with the substrate such that the distal ends may collapse toward the base as the distal ends engage the substrate to facilitate further movement of the base toward the substrate for application of fluid to each of the plurality of locations.

    摘要: A method, and an article produced according to the method, for embedding conductors in a structure having a signal distribution function associated therewith such as a vehicle instrument panel. The method includes embedding a conductor in a film, and molding a material to the film such that the material and the film integrally form the structure. The method also includes attaching a connector to the integral structure so that the connector is provided in communication with the conductor.

    摘要: Method of manufacturing a multi-layer printed circuit board adapted for reduce interfacial sheer stresses includes a laminate substrate having a top layer forming a first major surface, a middle layer having a predetermined thickness and a bottom layer forming a second major surface opposed to the first major surface. Etch resists are disposed on the first and second surfaces corresponding to reverse images of desired conductor patterns. The first and second surfaces are thereafter etched and the photoresist removed. The laminate substrate is secured via a low modules adhesive layer to a major surface of a base. The middle layer of the laminate substrate is thereafter selectively etched so as to isolate selected portions of the first and second surfaces and to define inner connect regions therebetween having a height equal to the predetermined thickness.

    摘要: A method and apparatus for forming a rigid circuit board has a circuit board with a reduced thickness in a bend region. The bend region may have several layers of laminate and conductive material. The circuit board is heated to the glass transition temperature which allows the circuit board to become flexible. The apparatus has a clamping member and a stationary member. The clamping member uses a shape memory alloy actuator with a transition temperature about the same as the glass transition temperature of the laminate. The actuator is used to form the bend region to a predetermined shape around the stationary member. When the circuit board is cooled, the circuit board again becomes rigid in its predetermined shape.
