摘要： A method and an apparatus for determining the eventual elongation property of a copper wire which has been cold drawn with an intermediate anneal and which is to be subsequently subjected to a predetermined heat treatment by a final in-line continuous anneal. Before a sample length of such wire is elongated to its breaking point in a tensile testing device, a capacitor is discharged through the wire length to produce a heating current flow therethrough of a magnitude and duration that produces a heat treatment of the wire length which approximately simulates that which would be the result of the final in-line continuous anneal. For this purpose, the wire holding devices of the tensile testing device have contact means to establish connection of the wire length in a discharge circuit for the capacitor.

摘要： A continuous process for high speed fabrication of wire comprises the steps of directing wire through a first set of drawing dies to reduce the wire diameter to an intermediate diameter, applying a lubricant to the wire during the drawing process, annealing the intermediate diameter wire while it is still coated with some of the lubricant, controlling the tensile forces and elongation of the wire during the anneal, and drawing the annealed intermediate diameter wire to a desired final diameter in a second set of dies. The process is particularly well suited for fabricating fine copper wire having improved mechanical properties.

摘要： Apparatus for measuring the modulus of elasticity of a sample specimen of a given thickness and area includes means for mounting one surface of the specimen on a rigid reference plane and an opposing surface of the specimen is then mounted on a rotatable surface. A torque arm coupled to the rotatable surface applies a predetermined torque which effectively causes this surface to rotate thereby twisting the specimen through a given angle. The angle is measured by means coupled to the rotatable surface, and based on the measured angle, one can calculate the modulus of elasticity in regard to the measured angle and in regard to the applied torque. The apparatus and methods essentially measure the modulus of elasticity through angular displacement of the specimen. The method and apparatus is particularly adaptable to measure the modulus of elasticity of a compliant layer associated with a printed circuit board which compliant layer acts as a stress relief layer for surface mounted components and solder joints coupling those components to the printed circuit board assembly.
