I. In order to eliminate SMT machine production process of high material throwing rate, it can not ignore the human factors, such as the common cause of high material throwing rate of the operation is the operator when the installation of material tearing belt is too long and too much pressure, the result will lead to material modification or loss of the situation, The solution is that the operator should keep two or three vacancies at the time of loading, and ensure that the operation of each link is standardized, and it is best to have a uniform standard of elasticity.
II. In the process of pick and place machine sample making, there was also a situation that there was sundries on the table after the installation of SMT Feeder, which caused the material to shake and could not be obtained. In such case, the operator should be trained to check whether there are sundries on the table and chassis of the machine when installing feeder, and the table of the machine should be cleaned in time when rotating and drawing. In addition, in order to ensure that the tray is not mounted on the large feeder, the operator must install the tray on the feeder during refueling to prevent the possibility of chuck or casting.
III. In the process of SMT patch proofing, the high material throwing rate may be caused by the reverse PCB or the wrong PCB, the solution is still required the operator in accordance with standard operating procedures to complete, And the work should be marked in the guidance book before the location of the board and the direction of the board and the daily summary of the matters needing attention. In this way, the efficiency and accuracy of the operator’s construction can be improved.
