In light soldering, short-wave infrared light is focused in the range of 1µm.
The light source is placed in one focal point of a semi-elliptical mirror so that all rays emitted by the light source are focused in the second focal point of the ellipse.
The radiant energy is converted into heat at the surface of the solder joint by absorption.
The radiant energy can be varied by the power of the light source, the duration of the radiation and the type of focusing.
The diameter of the focal spot is 2-3 mm, depending on the optical system.
Point - (LightBeamSpot) or band (LightbeamLine)
emitters are used for the respective application in light soldering..
Light soldering is particularly suitable for selective reflow soldering when joining partners with the same heat capacity are to be soldered.
