Hamamatsu Photonics offers new lineup of laser-heating systems

Hamamatsu Photonics has launched five laser-heating systems. This new lineup has optimised laser output powers and spot diameters, helping users select the ideal laser-heating system for applications such as laser soldering of microcomponents for smartphones, plastic welding of automobile parts, and thermal curing of adhesives to bond dissimilar materials.

Compared to conventional heating methods, laser thermal processing delivers higher efficiency at a lower environmental load, helping reduce carbon emissions for a more sustainable society.

These laser-heating systems are aimed mostly at domestic and overseas manufacturers of electronic devices and automotive parts.

Each of the five new systems consists of an LD irradiation light source, a laser transmission optical fibre, and a beam irradiation unit. All are designed and combined to exhibit optimum performance for specific laser thermal processing applications and tasks.

Hamamatsu Photonics designs, develops, manufactures and markets LD irradiation light sources for a broad range of thermal processing applications including laser soldering, plastic welding, adhesive thermal curing, drying, and hardening. The firm's optical design technology ensures the LD irradiation light sources emit laser beams with uniform intensity distribution on the irradiated surface to allow high-quality processing with no uneven or irregular heating. Another innovative feature is the use of a single optical fibre for both processing and measurement, which gives accurate thermal information at the laser irradiation point to ensure accurate control of processing quality.
