JPS6420462A - Repair supporting device for substrate - Google Patents

Abstract

PURPOSE:To quickly and surely execute an inspection and a repair without having a technical knowledge, by converting the cause to an abnormal operation of a circuit board, and the inspecting work contents of the circuit board, etc., to a data base. CONSTITUTION:A data of a substrate which is designed by a CAD 1 of a design and manufacture department A is stored in a substrate drawing data file 6, a parts characteristic data file 7, and a circuit characteristic data file 8, of a knowledge data generating means 5. A data base generating means 9 analyzes the cause to an abnormal operation of the substrate from the stored contents of the files 6, 7 and 8, generates an abnormality counter-measure data and stores its in a file 10. A repair data generating part 20 of a service department B reads out the contents of the file 10, executes weighting in accordance with the cause of a high frequency, etc., edits them to a repair data of the smallest number of data and stores it in a file 23. In case of executing a substrate inspection in a customer C, when a kind of the substrate is inputted, an inspecting method, the cause to its result, a countermeasure, etc., are displayed 33.
