Laser Soldering

Laser soldering is a process which selectively heats solder by means of laser irradiation (usually utilizing a direct diode laser) which forms a bond between two parts.

Advantages of laser soldering include:

• Localized/selective heat input
  • Ideal for heat sensitive components
  • Does not heat/damage adjacent components
  • High precision – spot sizes on the order of 100s of microns
• Fast control of heat input (laser on/off)
• Non-contact processing for joining in spaces with limited accessibility (vs. iron tip soldering)
• Efficient and homogeneous heat input

The primary application for laser soldering is laser soldering of circuit boards in the electronics industry.
