One, generally in the front of the production line we can use automatic or semi-automatic tin paste mixer stir tin paste, also can be used manually stirred, and then through the track to the automatic or semi-automatic wire printing machine, from the assembly line to the designated PCB plate and then finish a paste front operation, and then uniform tin paste samples to the SMT patch machine.
Second, after the PCB board came to SMT patch machine, we can formally processing mount production operation, usually we need to use multi-function patch machine for a work task, we can also choose different speed and type of machine, after our program in the system management software after the original stick on the PCB board to reflux welding operation.Three, when the PCB plate into the reflux welding area, usually different reflux welding machine has multiple temperature zone, generally three, six, or three different varieties of temperature, we choose the appropriate temperature, and then let the element can firmly on the PCB board so the whole production process is over, next will produce good PCB board to AOI detection system of SMT patch mount effect detection, if detected, from the new back, if no problem, end the task.
