Abstract
Official abstract text for this publication.
A method used to predict a strength of an ultrasonic weld-joint of a wire-cable comprising the steps of providing a wire-cable, determining a combined-weight, removing a contaminant, determining a weight, determining a percentage by weight of the contaminant, and determining whether the percentage by weight of contaminant is less than a threshold. Determining the percentage by weight of the contaminant removed from the wire-cable is based on a formula [(Mb−Ma)/Mb]*100, where Mb is the combined-weight of the wire-cable and the contaminant and Ma is the weight of the wire-cable. The threshold of the percentage by weight of the contaminant correlates to the strength of the ultrasonic weld-joint.
First claim
Opening claim text (preview).
We claim: 1. A method used to predict a strength of an ultrasonic weld-joint of a wire-cable, comprising the steps of: providing a sample of a wire-cable containing an organic contaminant; determining a combined-weight of the wire-cable and the contaminant; removing the contaminant from a surface of the wire-cable using a heat-source; determining a weight of the wire-cable after the contaminant has been removed; determining a percentage-by-weight of the contaminant removed from the wire-cable based on a formula [(Mb−Ma)/Mb]*100, wherein Mb is the combined-weight of the wire-cable and the contaminant and Ma is the weight of the wire-cable; and determining whether the percentage-by-weight of the contaminant is less than a predetermined threshold, wherein said threshold correlates to the strength of the ultrasonic weld-joint. 2. The method in accordance with claim 1 , wherein the wire-cable is a stranded-wire-core. 3. The method in accordance with claim 1 , wherein the wire-cable is formed from material selected from the list consisting of aluminum-based material and copper-based material. 4. The method in accordance with claim 3 , wherein the wire-cable is plated with tin. 5. The method in accordance with claim 1 , wherein the heat-source is an oven and wherein the method further includes the step of placing the sample inside the oven. 6. The method in accordance with claim 5 , wherein a temperature inside the oven is 300 degrees Celsius. 7. The method in accordance with claim 1 , wherein said threshold is 0.021 percentage-by-weight.
