What is the technology behind the laser soldering?
Laser soldering is a non-contact process: the laser beam heats up the solder. This is then introduced to the process as a filler wire, which usually consists of copper or zinc alloys. The solder then melts and fills the joint gap. The melt fuses the two components.
The two processes of laser soldering technology:
- Hard soldering using a laser at melting temperatures above 450 °C:
This joining technique uses diode lasers with higher power and is used primarily in the automotive industry.
- Soft-soldering using a laser at melting temperatures below 450 °C:
This technique is commonly used in the manufacture of electronic components.
