Development of PCBs Functional Tester with Relay Matrix Network

Abstract:

This paper presents the development of the PCBs functional tester and the application of matrix relay in this system. It is stressed on the structure of relay matrix switch and its basic control mode. A topology of cascaded relay switch network is also proposed. The relay matrix in switch networks can achieve flexible connections of I/O pins on the specific PCBs being tested with varies signal resources and output processing modules without any hardware changes in the different test flows, only by PLC program changes. Therefore, complex test wiring can be saved when interface varied, as well as the enhancement of systematic universality. .
