A.  Air Flow Meter   

 

This device is used to control and monitor the airflow  
through the reflow head. 

B.  Sensor Inputs   

 

The sensor inputs are K-type thermo-couples.   
Measured temperatures are displayed through the PC  
software in real time for use in making profile graphs. 

      C.  LCD Display Monitor 

 

Displays PC software. 

D.  Keyboard 

 

             Used to enter information into software. 

E.  Reflow Head 

 

 

Contains the top-side heater and moves up and down 

 via an electric motor that is controlled through the         
software. The reflow head is clutched to control  
downward force.  

F.  Cooling Fan 

 

 

The component and PCB are cooled by the cooling fan, 

 

 

 

 

 

and can be activated automatically after the reflow cycle 

 is complete or operated manually.
