The main applications of Hundred-watt level fiber delivered direct diode lasers include laser soldering and plastic laser welding.

With precise laser positioning and accurate temperature control, laser tin soldering provides a highly flexible solution for the introduction of lead-free soldering technology in the constantly developing modern electronics manufacturing indus-try. It features non-contact welding, fast rate of temperature increase and small heat affected area, making it more suitable for lead-free processing.

In laser transmission welding of plastic application, one of the materials needs to be able to transmit the laser, while the other material or the surface coating of it needs to absorb the laser. Under the action of pressure, the parts of the two materials that need to be connected move with the laser beam to form a connection band between the materials.
