PCBA automatic parallel insulation and voltage resistance testing system and device

Abstract

The invention discloses a PCBA automatic parallel insulation and voltage resistance testing system and device. The system disposed on the device comprises a product identification module for obtaining the information of a PCBA to be tested; a program loading module for loading a corresponding product testing program according to the information of the PCBA to be tested; and a product testing module for outputting an instruction according to the product testing program to drive a routing matrix switch in the device to switch and to control an insulation and voltage resistance tester in the device to output corresponding test voltage. Every time the product testing module drives the routing matrix switch to switch, two circuits with different voltage classes are selected on the PCBA to be tested to communicate with the output end of the insulation and voltage resistance tester so as to receive the test voltage output by the insulation and voltage resistance tester for an insulation and voltage resistance test.

Description

technical field [0001] The invention relates to the technical field of automatic testing of PCBA circuit boards, in particular to a PCBA automatic parallel insulation withstand voltage testing system and device. Background technique [0002] PCBA (Printed Circuit Board Assembly) circuit board is the core control unit of product functions, and its output is increasing day by day. In order to ensure that the PCBA circuit board has stable working performance, it is necessary to inspect the quality of the PCBA circuit board before leaving the factory. Among them, the insulation withstand voltage test is an important part of the quality inspection of the PCBA circuit board before leaving the factory. At present, the insulation withstand voltage test of PCBA circuit boards is basically carried out in a single-block manual or multi-block series connection method, which not only affects the efficiency of the product's insulation withstand voltage test, but also cannot ensure the qu...

Problems solved by technology

At present, the insulation withstand voltage test of PCBA circuit boards is basically carried out in a single-block manual or multi-block series connection method, which not only affects the efficiency of the product's insulation withstand voltage test, but also cannot ensure the quality of the product's insulation withstand voltage test

For example, due to the inability to detect the leakage current of the PCBA circuit board, there is a quality risk of poor insulation when the product leaves the factory

In addition, on the one hand, some irregular human operation processes will bring hidden dangers to the electrical insulation quality of PCBA circuit boards in the testing work. On the other hand, the insulation withstand voltage test is a high-voltage operation, and the high-voltage operating environment during testing will also bring safety to operators Hidden danger
