Application of Rthogonal Test in Controlling the Pass Rate of One Inspection
This paper takes the pass rate of one inspection as the research object,The main reason of solder joint defect is analyzed by welding mechanism,Identify the main factors affecting the welding quality of printed boards and components and the orthogonal test scheme of horizontal design.The analysis of the priority weights among the factors and levels of the test results is carried out with illustrations,The optimal combination scheme for manual welding of circuit boards with different characteristics is obtained,It can be realized to reduce rework,reduce costs and increase efficiency,To improve the pass rate of manual welding of circuit board,In order to ensure the quality and reliability of welding,it has certain practical value.
