How to Use Hot Air Rework Station on Cell Phone PCB

Safety first: Do not use the mobile repair heat gun or Hot Air Rework station on surfaces like a glass table, or study table which you don't want to be ruined. We recommend you use a piece of scrap wood or PCB Holder to work with the hot-air station on the mobile phone and laptop circuits.
Faults that cell phone technician detects on mobile PCB are by the ic in mobile. If you learn the types of integrated circuits ic and their problem, especially the power ic problem, you can repair cell phones in a short time with SMD Rework Station.

Step One: Attach the Rework Station Nozzle

Choose your nozzles first to do the soldering job. Now attach the nozzle to the top of the rework station handle, as you can see in the picture.

Step Two: Press the Power Button

Now press the power button to start the heating element on the handle of the rework station, then wait for hot air to come. Wait for the hot-air station to warm up before using it on the circuits. The red LED next to the “AIR TEMP” will pulse, then you get very hot air. Now aim the nozzle where you want to heat the Cell phone PCB.

Note: If you are using a hot air station for the first time, it is possible you see puffs of white smoke coming out of the nozzle. Will don't get scared. Those are solder clouds and that is normal. They will go away after a few seconds.

Step Three: Adjust Heat and Air Temperature from the knobs

Air is for airflow, and the Heater is for temperature. Adjust them us. You need them. Note: Don't set the heating temperature higher than the melting point of the solder and don't set air too much to blow your circuit components away when you're trying to fix them on the circuit. You set the air and heat temperature knobs to the middle and then test on a scrap PCB small component.

Step four: Rework or Resoldering the Cell Phone PCB

When you’ve got your settings honed in, always aim the nozzle Handle at the mobile phone PCB when you are working on it. Move the nozzle back and forth until the soldier begins to flow. The soldier should appear shiny. Then Handle reposition/remove the component you want to rework with the help of the tweezer by nudging or grabbing the component. Keep in mind that the hot air never gets a break during the entire process. Make sure to keep the mobile repairing heat gun handle moving to prevent any damage to the component or the ICs from burning. Aiming the heat gun at the same point can coss damage to the ICs after a certain period. Every component in the mobile phone circuit gets unsolder in a certain period. The training instructor knows it well and he can teach you. 


Some components in the PCB are glide heat sensitive. Some cell phones, basic electronics, and ICs have many values written on them. Which can melt while giving more heat from the rework station. Be sure to set the right heat on those components! If you see warping or smoke coming from the Phone PCB during re-soldering, remove the heat gun handle out of range of the working area on your PCB and turn your heat temperature down. When you did, push the power switch to OFF to allow the rework station to cool down when you finish your re-soldering work. The self-cooling system executes switches when you push the power button off. The heater metal element on the handle switches off, and the airflow is coming out for a few minutes until the element gets cool.
