I. Tips for operation   

1

. After turn on the head power switch, check whether the upper hot-air nozzle gives out 

cool breeze. If not, never start the machine, or the upper heater may be burnt.   

2.

  Set  different  temperature  curves  for  different  BGA.  The  temperature  should  not  be 

higher  than  250.  In  lead

-free  soldering,  it  can  be  set  according  to  the  soldering 

temperature curve of BGA soldering balls.   

3

. When desoldering BGA, turn the cooling fan to auto. After the temperature curve goes 

over,  the  buzzer  alarms  automatically.  Then  remove  BGA  form  PCB  quickly  with  a 

vacuum suction pen and take PCB away from the positioning bracket.   

4

. When desoldering BGA, turn the cooling fan to auto. After the temperature curve goes 

over, the buzzer alarms automatically. The cooling fan begins to cool BGA and the lower 

heating area. The hot-air nozzle gives out cold breeze at the same time. The upper main 

heater  arises  to  8-10mm  from  the  surface  of  BGA  and  pauses  for  30-40s.  Or  after  the 

working light is off, move the main heater away and take PCB away from the positioning 

bracket.   

5

. Before soldering BGA, check the PCB pad and BGA balls one by one. After soldering, 

check  the  appearance  one  by  one  again.  If  there  is  some  problem,  stop  assembling  and 

check  the  temperature.  Continue  after  adjust  it  well.  Or  the  BGA  and  PCB  may  be 

destroyed.   

6

. Clean the surface of the machine regularly, especially the infrared heating board. Don't 

leave dirt plot on the board to prevent it from radiating, or the soldering may be a failure 

and  the  life  of  infrared  heater  will  be  significantly  shortened.  (If  the  infrared  heater  is 

destroyed due to this reason, our company will not change it for free.)   

7

.  When  we  use  the  optical  place  system,  we  must  turn  the  self-lock  (heating  head  and 

nozzle) switch to auto, or the heating head and nozzle can not rotate freely.   

Those who are not trained by our company mustn't modify the parameters or disassembly 

the control box. 

 

 

 

Conclusion 

 

In the productive area of electronic products, especially the computer and communicative 

electronics  areas,  the  components  to  miniaturization,  multifuctionize  and  greenize. 

Different kinds of packaging technology emerge, while BGA/CSP is the mainstream.   

To meet the fast-increasing demand of BGA circuit assembly, the manufacture companies 

need to choose safer, faster and more convenient assembly and rework technology.
