Can I use a blow dryer as a heat gun?

As you guys know, I do many phone repairs and iPad Screen Replacements as well as iPhone Screen Replacements. All of these phone screen repair jobs require that the edges of the screen be heated. in the early ages since I started doing a phone screen repairing I use a blow dryer for heating the smaller areas and edges of the screen. for the experiment, I try an alcohol burner but its open flame damaged the edges of the screen because it is a spirit lamp laboratory equipment. From my experience I recommend do not use a butane torch, alcohol burner, clothing irons, 100 watts light bulbs, or hairdryer in phone screen repair.

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 is by the ic in mobile. if you learn the types of integrated circuit ic and their problem, especially 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 from the nozzle. will don't get scared those are just 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.

Adjust Temperature

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. we suggest you set the air and heat temperature knobs to the middle and then test on a scrap PCB small components.

we suggest you get a train in cell phone repairing with the hot air station, a hot air blower for cell phone repair to get the class of mobile phone repairing with the hot air station join

Step four: Rework or Resoldering the Cell Phone PCB

When you’ve got your settings honed in, always aim the nozzle carefully at the mobile phone PCB when you are working on it. move the nozzle back and forth until the solder begins to flow the solder should appear shiny. then carefully 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 whole 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 of time. every component in the mobile phone circuit gets unsolder in a Certain period of time. the training instructor knows it well and he can teach you. 


Some components in the PCB are Certain heat sensitive. some cell phone basic electronics and ICs have a number of values written on them. which can be melted 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 resoldering, remove the heat gun handle out of range of the working area on your PCB and turn your heat temperature down. when you are done, push the power switch to OFF to allow the rework station to cool down when you finish your resoldering work. The self-cooling system automatically switches on when you push the power button off. the heater metal element on the handle switch off and the airflow is coming out for a few minutes until the element gets cool.

Step five: Clean the PCB After Doing any Work with the Heat Gun Mobile Repairing

Wash your board with CTC (Carbon tetrachloride) when you're finished resoldering work, you can also do this work on water-damaged PCBs, to remove any water-soluble left on the PCB which can cause corrosion over time.

Common Problems and Their Solution During Work with the Heat Gun Rework Station

Question: Low Airflow When I Turned Up “Air” Dial to Full

Answer: If you are getting a low airflow problem on your rework station, make sure that you have the nozzle securely attached to the end of the handle. if you need more air at a specific area on the cell phone PCB use the nozzle, you will get more air flowing through the hot-air rework station.

No heating element fire up When I switch on the Rework Station or H-E Error

“H-E” means there is a heating error. It might be that there is something with the heating element failing on the handle or not connected properly with the internal wires on the rework station. First, open the rework station handle with the help of a screwdriver and reconnect the wires connections to see if the heating element needs to be re-seated. if the problem exists we recommend you change the heating element. the rework station might be able to be revived by removing and re-attaching the heater.
