Printed circuit board detecting method and system thereof

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...

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
