Light soldering

When light soldering short wavelength is infrared in the range of 1  micron wavelength to the soldering spot focused . For this purpose, the radiation source is arranged in a focal point of a mirror in the form of an open ellipsoid of revolution so that most of the rays emanating from it are focused on the soldering point in the second focal point of the ellipse. The radiation energy is converted into heat by absorption on the surface of the solder .

The radiation energy can be controlled via the power of the light source, the radiation duration. The type of focus determines the working diameter - the focal spot diameter is 2… 3 mm, depending on the optical system.
