Multi-station PCBA board detection method

Abstract

The invention provides a multi-station PCBA (Printed Circuit Board Assembly) board detection method, an adopted detection tool comprises an upper computer and a lower computer, the upper computer is provided with a plurality of PCBA board test programs, and the test programs comprise test process steps and preset thresholds of different parameters so as to detect different types of PCBA boards; the upper computer is provided with test data programs corresponding to a plurality of different test programs so as to record test results corresponding to the test programs; pCBA boards to be detected are placed on different stations of the detection tool; when the PCBA board to be detected is detected, the test program corresponding to the station is started through the control piece corresponding to the station, the lower computer transmits detection result data to the upper computer in time and stores the detection result data in the test database, and the actually measured values of different parameters in the detection result are compared with the corresponding preset threshold values, so that whether the PCBA board to be detected on each station meets the specification or not is judged.

Description

technical field [0001] The invention relates to the technical field of PCBA board detection, in particular to a multi-station PCBA board detection method that can be used to detect different types of PCBA boards. Background technique [0002] PCBA is the abbreviation of Printed Circuit Board+Assembly in English, which generally refers to the whole process of PCB empty board passing through SMT upper part or DIP plug-in. PCBA also refers to printed circuit board (also known as printed circuit board, printed circuit board), which is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. A large number of electronic components are welded on the PCBA. As one of the important components of modern electronic equipment, its quality directly affects the performance of the product. Therefore, after the production is completed, the inspection of the PCBA board is an indispensable and important step. ...

AI Technical Summary

Problems solved by technology

However, after the panel test is completed, some components will be damaged due to the impact of force when the panel is divided or broken, resulting in abnormal phenomena when the subsequent PCBA board is installed

[0004] Furthermore, conventional PCBA board test benches or inspection tools generally display bad information or signals of PCBA boards through the LED lights or display screens on the inspection tooling. For different types of PCBA boards, it is necessary to write different test software and hardware on the tooling. And the versatility of the test software and hardware is not good

In addition, the multiple stations in the existing multi-station PCBA board testing machine on the market basically test the same type of PCBA board at the same time, which cannot be used to test different types of PCBA boards or to test different types of PCBA boards at the same time
