Problems solved by technology

[0006] 2. During the power-on test, the PCB circuit is often seriously damaged due to the short circuit of the PCB itself or the problem of the parts
Under the limitation of existing technology, it is often impossible to complete the inspection action within the production line balance time of the production line, thus becoming the bottleneck of the production line, resulting in low production capacity of printed circuit boards

Embodiment Construction

[0021] The features of the present invention can be clearly understood by referring to the drawings and the detailed description of the embodiments.

[0022] The printed circuit board inspection method of the present invention can select two modes of complete inspection or interval inspection of the printed circuit board, wherein the complete inspection is when the AOI inspection time is lower than the line balance time of the production line, and the complete inspection mode is selected to follow the existing tradition way to inspect the printed circuit board. If the AOI inspection time is longer than the line balance time of the production line, you can choose the interval inspection mode to shorten the inspection time, so you can switch between different inspection modes according to your needs.

[0023] Among them, the interval inspection mainly divides all test items on the printed circuit board into secondary test items and main test items, and the secondary test items a...

Abstract

The invention mainly provides two detection programs which respectively contain main detection items and part of secondary detection items, and adopts a mode that a printed circuit board with the serial number being even and odd is respectively treated with initial detection by using the two detection programs, and dispersing detection flow is permeated so as to promote the detection speed of theprinted circuit board.

Description

technical field [0001] The present invention relates to a printed circuit board inspection process technology, and aims to provide a product inspection method and a system thereof which are especially suitable for the production process with high product quality reproducibility in the printed circuit board assembly process. Background technique [0002] Printed circuit board (PCB) appears in almost all current digital and non-digital electrical devices. In addition to fixing various electronic components, its main function is to be able to provide interconnection between the above electronic components. The function of current connection to achieve the expected function; as the functions of electronic products and equipment become more and more complex, the number of electronic components on the printed circuit board is also increasing. When the density is higher, the product inspection of printed circuit boards becomes an extremely critical technology and process due to the...
