CCD calibration and Mark point similarity adjustment
Then there is a calibration move distance button below this, as mentioned earlier CCD calibration has a move distance, this is a fixed value, do not change it, as well as the rotation angle is the same, do not change it. Alignment mode why is the choice of centered alignment? In the printing process will certainly encounter a situation, that is, elongated or shortened, if the first printed pattern is elongated or shortened, then the second printing and the first printing is certainly not right; may be a little larger or smaller, then how to do? Open the center, set all the printing to the center alignment, so that it will find a middle value to print. In order to achieve the printing effect, the adjustment is divided into a variety of modes, basically the direction of the printing operation is centered alignment.
Similarity is about finding the MARK point printing, MARK point has debris on it, causing the mark point to have mutilation or foreign matter MARK point becomes larger. Then this time to find the MARK point may not be the same, there will be alignment on the wrong, then how to do? Change the similarity to a lower value. In other words, the smaller the value of similarity, the lower the similarity, the larger the value, the higher the similarity; the larger the value, if the MARK point and the material above the MARK point has a defect, there will be a little bit of failure to match, which is equivalent to the failure of finding the point. In this case, the similarity should be lowered; however, it is advocated that the similarity should be increased, so that the printing will not be misjudged. The summary is: in case of this situation, MARK point problems, you can lower the similarity of the MARK point, and then print, in the printing process of deviation, alarm these aspects of the problem, basically in this can be solved.
