Network partitioning method and network partitioning device of electrical performance testing points of PCB (printed circuit board)

Abstract

The invention discloses a network partitioning method and a network partitioning device of electrical performance testing points of a PCB (printed circuit board). The method comprises the following steps: partitioning initial testing points on the PCB in terms of network forms, testing points or network; and reserving a plurality of testing points for electrical performance test after partitioning. With the adoption of the network partitioning method and the network partitioning device, the electrical performance testing efficiency of the PCB is improved; the testing cost is reduced; furthermore the network partitioning method and the network partitioning device are not limited by the products and the testing machine tools; the test is more convenient and rapid; the production capacity is increased greatly; and the activation of the testing machine tool is improved. With the network partitioning method and the network partitioning device, the problem that the selection of the testing instruments and testing machine tools is limited because the PCB product is light, thick, short and small and dense in circuits and pores is solved; and the testing production capacity and the management efficiency of the PCB are improved.

Description

technical field [0001] The invention relates to the field of PCB testing, in particular to a method and device for network segmentation of PCB electrical performance testing points. Background technique [0002] During the production process of PCB, it is inevitable to cause electrical defects such as short circuit, open circuit or leakage due to external factors. In addition, PCB is constantly evolving towards high density, fine pitch and multi-level. Therefore, the electrical performance of PCB Testing is especially important. The electrical performance test of PCB is to use the current pulse to test the open and short circuit of the PCB. The test method generally adopts the test fixture, which is generally combined with the test machine. The general test fixture is divided into double density and four density. According to Depending on the shape and size of PCB products, different test fixtures and test machines can be selected. [0003] With the continuous update of PC...
