Canon Optic Lithographic Printing Press Machine Control Board Repairing needs to observe the target appearance carefully. If the board is burned, then Before powering up the control board, be sure to check the power circuit carefully.
Normal, turn on the power after ensuring that no secondary damage is caused. Observation it is a kind of static inspection method. When using the observation method,
Follow these steps.
The first step is to observe whether Canon Optic Lithographic Printing Press Machine Control Board has been artificially damaged. This is mainly from the following aspects:
① See if the electronic controller board has been dropped, causing the board angle to change shape, or the chip on the board has been deformed or broken.
② Observe the socket of the chip to see if there is no special worker tools, while being forced to pry.
③ Observe the chip on the printed circuit board. If it has a socket, first observe whether the chip is inserted incorrectly. This is mainly to prevent the operator from inserting the chip in the wrong position or direction for assemble faulty in electronic circuit card. If the errors are not corrected in time, when the PCB board is powered on, the chip may be burned out, causing unnecessary losses.
④ If there are short-circuit terminals on the electronic card, observe whether the short-circuit terminals are inserted incorrectly.
The maintenance of electronic motor Control Board requires a solid foundation in theory, careful work, and careful observation by the maintainer, and sometimes the cause of the problem can be determined at this step.
