Abstract

The invention discloses an on-line circuit board test and maintenance system for testing circuit boards with barcode and automatically uploading test information in real-time and repairing bad circuit board, including an online testing machine, a workshop control server, connected to the online testing machine, and a maintenance workstation. The workshop control server includes a functional module for the collection, transmission and handling the test data generated by the online testing machine. The maintenance workstation sets up at least one maintenance computer to show error information about bad circuit boards. The maintenance computer is connected to the workshop control server.

Description

【Technical field】 [0001] The invention relates to a circuit board online test and maintenance system and method, in particular to an ICT (In-Circuit Tester, online tester) online test information real-time automatic upload and paperless maintenance system and method. 【Background technique】 [0002] ICT online test is the most commonly used circuit board test method in the production process at present. It is widely used in electronic manufacturing enterprises. Its main purpose is to check the open and short circuit conditions of individual components on the circuit board and each circuit network. It is easy to operate. , Accurate fault location and so on. Through the online test of the circuit board, the bad components and manufacturing defects on the circuit board can be quickly checked out, and a diagnosis and maintenance report can be provided at the same time. [0003] In order to facilitate control, the test information of the online test of the product should be uploa...
