Industrial VCSEL Heating Systems

Individually controllable emission zones for high-precision processing

Industrial VCSEL Heating Systems

Beam sources based on VCSEL arrays are able to heat large surfaces with directed wavelength-selective infrared radiation. These VCSEL heating systems are used in numerous industrial heating processes. Due to direct irradiation of the treatment surface, significant cost benefits can be achieved compared to conventional laser systems, without expensive optics or scanner systems. The unique thing about the systems is that, in addition to the precise control and fast switch-over of the infrared output, the spatial heating profile can also be programmed as needed through independent control of small segments of the laser modules. The heating patterns can even change dynamically during operation. This enables unparalleled process flexibility.

Scalable power

Benefit from a scalable output power in the kW range.

High power density

Achieve a high process speed with irradiance of 100 W/cm².

Can be controlled precisely

Individual emission zones of the VCSEL beam source can be controlled independently of one another.

Simple integration

The robust and compact laser modules can be integrated easily into industrial systems and production processes.

Large-area heat treatment

Benefit from direct and homogenous heat treatment of large target areas, as well as from a high tolerance to back-reflections. Due to the high irradiance of over 100 W/cm², you can achieve high process speeds.

Flexible control of the heating profile

Enjoy the benefits of precise regulation of the heating power and free control of the heating profile in a longitudinal direction.

Fast joining of large plastic parts in furniture board production

Benefit from quick welding of large plastic parts due to high irradiance in the homogenously irradiated heating zone. Integration is very easy due to the small dimensions of the module.

Local softening of body steel in the automotive industry

VSCEL heating modules make it quick and easy to selectively soften high-tensile steel parts. This has many benefits, particularly in automotive production.

E-mobility: drying battery foils

The active material on the electrode foil must be dried after the recoating process. Industrial VCSEL heating systems can perform this step, because beam sources based on VCSEL arrays are able to heat large surfaces with directed wavelength-selective infrared radiation.

E-mobility: sealing pouch cells

Using VCSEL heating systems to seal pouch cells increases the quality of the sealing results. In addition, the process time is reduced. The process is up to three times faster in comparison.

FURTHER INFORMATION

Wafer heating

VCSEL lasers can be used in the semiconductor industry for heating the wafers for Rapid Thermal Processing (RTP). VCSEL heating modules make it possible to heat the wafers quickly and uniformly as the individual heat zones can be superbly controlled. Temperature increases of several hundred degrees Celsius can be achieved per second.

Component generation using laser metal fusion

Additive manufacturing with metals (preheating)

In so-called selective laser sintering (SLS), a focused laser beam melts plastic powder locally, thereby generating the component. This is made possible by the highly innovative VCSEL heating system from TRUMPF, which contains over 3,000 individually controllable lasers (VCSEL arrays). The production speed is thus increased by a factor of 10 compared to conventional 3D printing machines, in which one or two lasers scan the construction area. In particular, applications in plastic injection molding can be implemented with high productivity using this technology.

Photovoltaics: laser-powered co-firing process, ultrafast regeneration und light soaking process

VCSEL heating systems open up numerous benefits in solar cell production. For example, during the process of selective burning-in of the contacts on the solar cell. There are benefits for regeneration processes as well: the intensive irradiation of the cell decreases defects and removes energy barriers, therefore increasing efficiency.

FURTHER INFORMATION

Semiconductor production: Laser Assisted Bonding (LAB)

Using solder balls, a flip chip is positioned as a connecting element on a printed circuit board in Laser Assisted Bonding (LAB). The VCSEL heating system irradiates the chip from above and the laser energy is transferred by a silicon chip in order to melt the solder balls between the chip and the printed circuit board. Compared to other solutions, the VCSEL heating systems provide larger heating surfaces with higher performance options.

Semiconductor production: Laser Assisted Soldering (LAS)

In Laser Assisted Soldering (LAS), the solder balls are connected directly with the soldering pads on the printed circuit board using VCSEL infrared heat treatment. This is particularly interesting if smaller solder ball and pitches are used. The VCSEL heating system technology offers highly precise heating and top solder joint quality. The LAS process also helps to increase the service life of printed circuit boards.

In so-called selective laser sintering (SLS), a focused laser beam melts plastic powder locally, thereby generating the component. This is made possible by the highly innovative VCSEL heating system from TRUMPF, which contains over 3,000 individually controllable lasers (VCSEL arrays). The production speed is thus increased by a factor of 10 compared to conventional 3D printing machines, in which one or two lasers scan the construction area. In particular, applications in plastic injection molding can be implemented with high productivity using this technology.

Control software for VCSEL heating systems

Basic Driver Control Software

The basic version of the control software offers the function of manually controlling the laser channels of the VCSEL heating system and of setting the power.

Advanced Driver Control Software

The extended control software version is based on the basic version and offers additional functions such as temperature control or pulsing. In addition, time and performance profiles can be created. These can be used to vary the power of the VCSEL heating system during the processing time.

Lenses

The heat density of VCSEL heating systems can be influenced with additional lenses. The irradiance of VCSEL modules can be increased with positive lenses. The use of negative lenses decreases the irradiance of the modules.

Air Knife

The Air Knife can be used to keep spatter and steam away from the protective glass of the laser system. It creates a protective airflow in front of the laser.

Mounting bracket

Mounting brackets simplify the technical assembly of the VCSEL heating module.

Reduced irradiance

A VCSEL heating module with less tightly packed emitters and a defocusing lens can be used for applications requiring less irradiance.
