Follow these instructions to use a heat gun to soften adhesive. Using a hair dryer is similar, but its procedure varies slightly.
A heat gun is a handheld device that emits a stream of hot air, usually at temperatures between 100 °C and 550 °C (200-1000 °F), with some hotter models heating up to 760 °C (1400 °F).
Before beginning, refer to the specific repair guide for detailed instructions such as the adhesive location and any surrounding sensitive components. Check your heat gun's user manual for any specific operating or safety procedures.
While heat guns can reach temperatures up to 1000 °F and higher, softening adhesives for electronics only requires a maximum of 200 °F. This can easily be achieved with the heat gun's low to medium-low setting.
Always start with the heat gun's lowest flow speed and temperature settings to avoid overheating the device you're working on.
If your heat gun has fine control over the temperature, keep it in the mid-to-low range. Anything higher could deform plastic or damage internal components.
When not in use, set the heat gun on a stable surface. The nozzle will remain hot after use.
