1x16 Post Weld Continuity

Abstract

Laser welding is a critical process of medical device used for the manufacturing process of spinal cord stimulation leads that brings different offenders. The highest for 1x16 family is continuity failure with 4% of rejection rate. It intended to improve the process with a new post weld continuity as an early detection point to avoidscrap and recover the unit as RWK. Improvement consists of to change the manual inspection for an automatic that allows to maximize the inspection time with an improvement of 68 seconds. Benefits from improvements include product output, yield, less scrap, process performance and financial area. Process performance is evaluated by the technique of the operator with the automatic check through unit position, time and correct inspection order. A P-chart results demonstrate the improve and control in continuity with a rejection rate of 3.6%. The welding process will continue to be evaluated to reducing the % rejection.Key Terms – Continuity, Laser welding,Medical Devices, Scrap.
