Laser soldering is a technique where a 30–50 W laser is used to melt and solder an electrical connection joint. Diode laser systems based on semiconductor junctions are used for this purpose. [21] Suzanne Jenniches patented laser soldering in 1980. [22] Wavelengths are typically 808 nm through 980 nm. The beam is delivered via an optical ...
Laser sintering of gold is a jewellery manufacturing technique [1] first developed by Towe Norlén and Lena Thorsson. [2] Laser sintering [3] of gold starts with gold powder, fine as flour. A laser beam sinters (melts) the gold flour locally in an extremely small point, and any shape may be ‘drawn’ precisely with the laser beam, in three ...

Brazing and hard soldering use a higher temperature filler that melts at a temperature which may approach that of the base metal, and which may form a eutectic alloy with the base metal. Filler alloys have a lower melting point than the base metal, so that the joint may be made by bringing the whole assembly up to temperature without everything ...
