. Do not bump, hit, pour water/liquids or otherwise subject the heating surface to physical shock. This may damage the heater. 4. To isolate the equipment from the mains before commencing repairs or making any maintenance to avoid electric shock. This may result in Death or serious injury. 5. Do not expose the unit to moisture nor use the unit with wet hands. 6.
faulty, discontinue using immediately. To comply with safety standards, the pump or other part must only be replaced by authorized technicians as special purpose tools are required. Only the technician is permitted undertake repairs. Use the original replacement part only. ● Remember unplug in the power cord: The station must be switched off and the power cord must be unplug-in before replacing the fuse in AC socket in rear side of the machine.
PRODUCT DESCRIPTION The temperature controlled Hot-Air LF-852DII SMD rework station built in an intelligent microcomputer chip which is specially designed for the present lead free SMD chips such as SOIC, CHIP, QFP, PLCC, BGA etc reworks to meet RoHS requirement. This appliance equipped with a high power heating element and gets very fast heat up time. A high-quality sensor and heat transfer technology ensure precise temperature regulation is essential for making consistent, reliable.
OPERATING PRECAUTIONS 1. Make sure both heater and nozzle are cool before attaching the nozzle. 2. Caution High Temperature Operation Do not use the LF- 852DII near ignitable gases, or other inflammable materials. Both nozzle and hot air are extremely hot and can cause burns. Never touch the nozzle and heater assembly or allow the hot air to blow against your skin. Initially, the iron may emit white smoke, but this will soon dissipate. 3. Be sure to cool the unit after using.
Caution: Check carefully for any damage during transportation and ensure that the working voltage matches your power supply before plugging in the station. 1. Ensure that the base unit power switch is in the “OFF” position. 2. Plug in AC power cord and turn “Mains power switch” to “ON” position then the temperature LED and wind LED display will be ON and show the value. 3. Press “▲” or“▼”key on the left side of the front panel to choose the desired temperature.
When temperature display window shows "F-2" and blinking, press the "SET" button, at this time, the system enters the degrees Fahrenheit and Centigrade temperature selection function, indicating the temperature of the window shows the current status. Press "▲" or "▼" key to change the temperature selection status. It expressed as degrees Celsius temperature value if set to ℃; it shows as degrees Fahrenheit temperature if set to ℉. GRIP DETECTION FUNCTION 1.
Note: After the power switch off about one minute later, the temperature will fall down to 75℃ (167℉) and power automatically shut off. 5. Remove any remaining solder: After removing the IC, cleaning the remaining solder chips with a wick or desoldering tool. Note: For SOP, PLCC etc. would recommend by using tweezers iron to desolder. QFP Soldering 1. Apply the solder paste: Apply the proper quantity of solder paste and flux (preferably no-clean) and place install the SMD on the PCB. 2. Preheat SMD. 3.
