When there is no hot air gun or infrared soldering iron

Sometimes you need to unsolder a microcircuit with a large number of legs. It is almost impossible to do this with a regular soldering iron without damaging the tracks or the microcircuit. This operation is usually done using a special hot air gun for soldering or an infrared soldering iron. If you do not have such equipment at hand, and you really need to urgently repair the device by replacing the microcircuit, then a regular halogen lamp, which is used in a car, will come to your aid.

Yes Yes! Halogen is an excellent source of infrared heat, and directed action.

For soldering, it is better to take a 55-watt low-beam lamp, or you can use a higher power one, 100 watts. Why is low-beam better? – Because halogen low beam lamps have a mini reflector. In a car, it serves to limit the areas where the lamp glows, but in our case, it will not only protect our eyes, but also reflect useful infrared rays and direct them in the right direction.

Precautions when working with the lamp:

- The light of the lamp is very bright, so you cannot look at the direct light stream.
- Wear sunglasses at least during the soldering process.
- During operation, the lamp becomes very hot, be careful not to get burned.
- Even after you turn off the lamp, let it cool for 5-10 minutes, as it is very hot.
- Do not touch the glass of the lamp with your hands. If you accidentally touch it, degrease the glass, naturally while it is off. In short, if this is not done during operation, the grease from your hand will heat the glass and the lamp will crack.

It is advisable to use a regulated power supply to power the lamp so that the soldering temperature can be adjusted.

Soldering with a halogen lamp

The lamp provides good local heating. Turn on the lamp and bring it to the element that needs to be desoldered. We wait about 0.5-2 minutes, this should be enough. After which the part easily comes off the surface.
