the AOI automatic optical detector is used to detect PCBA welding in SMT production line9 T* ~" O3 k0 k2 n# c. V# [.
]7 ~, M& s" ^: |+ B' P     According to the position of AOI detection equipment in the production line, we can divide it into pre reflow detection and post reflow detection. According to AOI detection circuit board automation status, we can divide it into online AOI optical detection and offline AOI optical detection. According to AOI detection principle, we can divide it into image contrast AOI optical detection technology and vector analysis detection technology, which are specific to each factory's own equipment procurement plan, You can make a choice according to your own production conditions, capital status, etc. we won't talk more about it here.

it also includes its derivative statistical modeling technology. In order to reduce false positives and improve the detection quality, vector analysis detection technology is more popular, and the price is not cheap.
