Product Use:
1. Install and power on:
– Open the package and take out the mainframe. Remove the red screw at the bottom of the body (- be sure to pay attention! )
– Turn on the 220V power supply to use. Turn on the power switch (POWER), the system can begin to work.
– Note: the first use of hot air suction tin demolition gun may be white smoke, a normal phenomenon.
2. Hot air hxad use:
– Power switch on, according to the need to choose a different wind nozzle and tin needle (has been equipped with accessories), and then the hot air temperature adjustment knob (HEATER).
– Adjust the hot air temperature knob (HEATER) to the appropriate temperature, and then adjust the hot air volume adjustment knob (AIRCAPACITY) to the required air volume, When the preheating temperature reaches the adjusted temperature, it can be used. If you don’t use it for a short time, you can adjust the hot air volume knob (AIRCAPACITY) to the minimum and the hot air temperature knob (HEATER) to the minimum.
– knob (HEATER) to the middle position, so that the heater in the insulation state, and then use, adjust the hot air volume knob, hot air temperature knob that can be.
– Note: For different packages of integrated circuits, replace the special air nozzle of different models. For different solder joint size, choose different temperature air volume and air the distance between the nozzle and the board.
3. The disassembly of the direct plug components:
– According to the above, so that the hot air part of the normal work, according to the size of the pad to replace the appropriate nozzle and suction tin needle (with accessories), heating can be.
– According to the different circuit board materials and different pads, choose the appropriate temperature and air volume. This method is suitable for a variety of single and double panels and a variety of different sizes the solder joints.
4. SMD components disassembly:
– Chip component disassembly: according to the different line substrate materials to select the appropriate temperature and air volume, so that the wind nozzle against the chip component pins, repeatedly and evenly uniform heating, to reach a variable temperature, with tweezers to slightly increase the force of its natural detachment from the substrate.
– SMD components of the soldering: in the location of the SMD components have been removed coated with a layer of flux, and then the solder tray leveling, with hot air to flux blowing evenly, alignment align the position, put the SMD components, with solder positioning. In the – – SMD components should be soldered place, all pile on the solder (pile tin method), and then according to above to remove the excess solder, with a soldering iron can be slightly shaped. With this method of soldering SMD components, beautiful joints, welding quickly and firmly, reliable.
Note:
1. In the hot air welding gun internal, equipped with overheating automatic protection switch, the gun nozzle overheating protection switch action, the machine stops working. Must be the air volume knob (ATPCAPACITY) to the maximum, delay about 2 minutes, the heater can work, the machine back to normal.
2. After use, pay attention to cooling the body: off, the heater will automatically spray cold air for a short period of time, in this cooling phase, not in the unplugged power plug head.
3. When not in use, please put the handle on the bracket to prevent accidents.
4. More detailed instructions for desoldering, please see the manual.
