Secondly, referring to the SMT stacking table, the SMT operator marks the mounter and flight position corresponding to the materials on the receiving tray, and uses a four-digit code to indicate the specified mounter and flight position. The first code can be a, b, c and d, corresponding to three JUKI jumpers. A, B and C represent the first, second and third mounters of J 1 and JBOY3 jumper respectively. A and B represent the first and second mounters of J2 jumper respectively, corresponding to Casio mounters. They are a, b, c and d. The second code is F and R, where F stands for installation on the front Feida support platform and R stands for installation on the rear Feida support platform. The third and fourth digits are Arabic numerals, representing the number of the arrival location to be installed.

Third, confirm the polarity of the component. If it is inconsistent with that marked in the workstation table, it needs timely feedback.
4. Install the tray marked with the function mounter and the position of Feida on Feida, write down the four-digit code specifying the mounter and the position of Feida on the label paper, and stick the P/N of the material at a fixed position behind Feida for easy viewing.
5. Load the loaded Feida onto the Feida revolving car, push the revolving car onto the mounter, and install it on the Feida supporting platform of the mounter according to the installation position on the stacking table. After self-inspection, the mounter operator shall notify the relevant personnel for re-inspection and inform IPQC to inspect the materials. After the inspection, fill in the feeding record form in time, and LQC will fill in the feeding record form after completing the first inspection.
6. Please refer to the above steps 2-5 for refueling in the production process.
Seven. Component conversion with different packaging methods: usually, the stacking table only sets the stacking position of tape packaging components, and the conversion between tape packaging, tube packaging and TDS tray packaging components will involve the change of stacking position, and the changed contents need to be filled in the SMT temporary change record table; The angle of the chip may also need to be adjusted when converting components with different packaging methods. The adjustment of chip angle is completed by the debugging personnel and recorded in the Temporary Change Record of SMT Stack Position. Angle adjustment? Signature record.
Eight, pipe installation regulations: IC pipe should be labeled with mounter, flying position and material P/N. Before pipe installation, check whether the components in IC pipe are in the wrong material or direction; The component direction should be loaded in the forward or left direction of the component polarity. The polarity direction is the first priority, and it will leave only when the polarity direction is not suitable. The changed polarity direction of components will be recorded in the temporary change record table of SMT stack position. C parts with similar appearance should not be arranged in adjacent positions as far as possible, so as to avoid wrong materials and mixed loading; When replacing a pipe for filling, it is necessary to carry out self-inspection, re-inspection, LQC inspection and IPQC inspection, just like replacing a package. Tube loading changes frequently, and materials should be checked and recorded in time after tube loading.
