Testing Quality of Elctronic Devices

Abstract

Quality is the degree of conformance of the product to the applicable specification, guidelines, and workmanship criteria. Quality control and quality engineering are involved in developing systems to ensure products or services designed and produced to meet or exceed customer requirements. These systems are often developed in conjunction with other business and engineering disciplines using a cross-functional approach. Quality and reliability are two of several important attributes required to satisfy the expectations of a customer. Reliability is the extent to which a product performs its intended function over its intended life under the life-cycle loads encountered. Quality conformance and qualification activities address the quality and reliability of product. Quality conformance includes all process control and quality assurance activities. The specific activities are qualification testing to ensure reliability and product and materials evaluation testing for quality assurance. The qualification and quality conformance are used in varying contexts in the industry. The objectives of this research is analyzing the measure of High Definition Television (HDTV displays) devices parameters data by design a user interface screen developed using turbo C++ language in which a comparison of the standard and the result of the device under the test. The standard which is used as reference data is International Electrotechnical Committee (IEC) these commission is professional in all electrical and electronic equipment. The research describes the procedure used in the IEC standards to determine the quality of HDTV picture and the methods of calculating the result. The program allow the operator to feed the measured values manually then calculate and make decision whether the device is complying with the requirement or not and print out the result.
