Title: Good/defective item discriminating method for in-circuit test
Inventor: KADOKURA AKIRA
IPC: G01R31/28
Filed: 2000-06-21
Abstract: PROBLEM TO BE SOLVED: To prevent mixing of a pseudo-good/pseudo-defective item in a good/defective item discriminating method for an in-circuit test. SOLUTION: This good/defective item discriminating method is constructed of a process for extracting an immeasurable part, a process for extracting an undetected part, and a process for detecting a good/defective item. In the process for extracting the immeasurable part, an equivalent circuit is formed by detecting a part mounted to a printed base board or a node of a circuit, while a measurement ability parameter based on a measurement circuit for a part unit test is formed previously, and from the equivalent circuit and the measurement ability parameter, a part beyond a limit of the part unit test measurement ability or an immeasurable part is retrieved so as to be extracted as the immeasurable part.  In the process for extracting the undetected part, a part unit test is carried out on a part excluding the immeasurable part, and on the basis of its good/defective discrimination result, a potential good/defective item is discriminated, while influence of the detected defective contents on the part unit test determination result is retrieved from the equivalent circuit for extracting an affected part as the undetected part. In the process for detecting the good/defective item, the good/defective item is detected by excluding the extracted undetected part from the potential good/defective item.
