  • Page 7 9. Collocating with sound control "early warning" function. It can warn workers to make some relative preparation 5-10 seconds before the completion of uninstalling or welding. Cooling system will start after vertical wind stopped heating. When the temperature drops to normal temperature, the cooling process will stop automatically, so that the machine will not be aging after temperature heated up.
  • Page 8 put out, withdraw the hot wind head.Finally, take away the PCB board from the heating zones. (1) null welding： Because of counterpoint by hand will cause deviation between chip and welding plate, surface tension of tin ball will make BGA chip and welding plate in the process of automatic correction. Once heating, BGA falls not evenly, which cause the chip drops not evenly.If stop reflowing at this time, the chip will not fall normally,which will cause th phenomenon of empty welding and false welding.So you need to extent time of third 、forth temperature zones or add the bottom...
  • Page 9 In this interface, the temperture can be changed and saved. User can set the heating temperture, the constant time and the heat speed according to the requirements of the production process. The machine can be mass storage temperature curve.User can store a a variety of manufacturing process parameters in the system.when replaceing of the production process, direct call to the parameters saved in the system, equivalent to formulation saved in the system.There are different heating temperature with different products,it can save various kinds of paraments in the different formulation,and it will be easy to use it when changed...
  • Page 10 If have to input new parameter, click the button of “curve choose”, and then click on the numerical place, the input button will appear. Input the parameter you need, press“ENTER” key.When temperature parameters Settings of these three temperature zones are finished, click “save curve”, then all parameters you have set are all saved.
  • Page 11 And it also can be changed and saved by “curve chooses”. Click „Start‟,the whole station starts to heating,and the working curve is showing the current parameter，and it will also clear the previous curve showed on screen.The whole heating will complete until the upper setting temperature or the upper part of the heating rate is zero,and just the machine stops running,with the alarm ringing, if the cooling vacuum interface has been set up within the cooling and vacuum state, then these two output also work.if click „stop‟...

  • Page 15: Concluding Remarks

    areas depend on the PCB board size. 2. You should set different temperature curves when repair different BGA,each temperature should not higher than 300℃；Lead-free rework setting can refer to welding temperature curve of BGA tin bead. 3. When demount BGA,the cooling fan and vacuum should be setted to automatic transmission,the buzzer will warn automatically when temperature curve runs to the end.Meanwhile, remove the BGA from PCB board with vacuum pen, and then remove the PCB board from the positioning frame.
