Abstract:
1. A system for analyzing a surface condition of a printed circuit board (PCB) using RGB colors, comprising: feeding means for feeding a target PCB, to be measured, to an image pick-up position where pick-up means is disposed; the pick-up means for picking up an image of a metal surface of the target PCB fed by the feeding means, and externally transmitting data of the picked-up image; and signal analyzing means for setting relative RGB values derived through a moisture absorption test carried out for a comparative PCB at intervals of time, extracting pixel data from the picked-up image of the target PCB received from the pick-up means, performing a mapping operation for RGB signals of the extracted pixel data, thereby determining relative RGB values, and comparing the determined relative RGB values with the relative RGB values derived through the moisture absorption test, thereby producing cumulative distribution data of the relative RGB values for the target PCB.
