The Progress of Automation and the Improvement of Reliability in Production of Color TV Receivers

Manufacturing techniques of color TV receivers as well as other electronic equipment have made remarkable progress. Many approaches to automation have been tried in the past. The authors´ activities concerning l) the development of modular chassis, 2) the automatic drafting system of printed circuit boards, 3) the automatic component inserting machine and checking facility used for printed circuit boards, 4) the automatic aligning and testing system applied to printed circuit boards, and 5) the automatic measuring system for color TV receivers are presented. Also, the concept of quality control of components and material is presented since quality control is essential for the attainment of reliability and automation. Through these activities and developments productivity has trebled during past several years, and the reliability of color TV receivers currently produced is over 20 000 hours mean time between failures (MTBF).
