​Geothermal hot air welding machine is connected to air heating soldering welding functions, black box is a pump, the performance good pump noise is small, the effect of pump is continuously blowing air, air flow along the rubber tube flow to the front of the handle, the handle is welded inside heating core, after electrify heats up, the air inside out will take the heat out of the wind down. Every welding machine is equipped with multiple wind mouth, different with different chip to use of the wind, in fact, now most of the technical personnel of the wind using only one or two can complete most of the welding work, namely the round hole used most frequently. According to our usage, hot air soldering station generally choose 850 models, its maximum power is 450 w, in front of two buttons, one of them is responsible for adjusting wind speed, the other one is to adjust temperature. Must be removed before using the airframe at the bottom of the screw pump, otherwise it will cause serious problems. After use, remember cooling airframe, clearance after electricity, heat pipes will automatically short jet refrigeration, in the cooling time, please don't pull the power plug. Otherwise it will affect the service life of heater. Note that wind 850 when looking for a job and it breathes the hot air temperature is very high, can burn people, do not touch, when you replace the wind and after I can come down the temperature of the operation.

Using hot air soldering station integrated circuit block actual operation method of replacement as follows: first, turn on the power, adjust the air flow and temperature control knob to keep the temperature between 250-350 degrees, will play an extractor under integrated circuit block, make the nozzle on the heat to melt the chip pin, to melt all the pins, can raise the extractor, take down the chip. After remove the chip, can apply a suitable amount of solder paste on the circuit board welding plate, with the mouth heating pad level as far as possible, and then apply a suitable amount of solder paste on the bonding pad, will replace the chip alignment on the circuit board, with the wind to blow out pins evenly heat, after all the pins of melting, welding is completed. Finally, attention should be paid to check if there is a short circuit welding components of virtual welding.
