Highly reflective substances, such as copper, absorb green light better than infrared light. As a result, compared with continuous wave lasers you need much less pulse power with the TruDisk Pulse. With a peak pulse power of up to 4 kW, the TruDisk Pulse enables fast, highly efficient welding processes, which is especially important in the electronics sector. Because of the minimal scattered radiation, you can also avoid the need to shield temperature-sensitive electronic components in some cases.
Green light for copper welding
The pulsed high-power laser, TruDisk Pulse, enables you to efficiently weld highly reflective materials, such as copper. The optimal absorption, as well as the high peak pulse power of 4kW with pulse durations in the milliseconds range, enables unparalleled application results when welding points and short seams. The laser is therefore predestined for use in electrical engineering and electronics. The TruDisk Pulse is based on the proven disk laser technology.
Many highly reflective materials, in particular copper, absorb green laser light much better than infrared light.
Prevent spatter through more uniform heating and a more stable weld pool.
The stable welding process results in more consistent diameters for weld points and weld seams, as well as uniform welding depths.
The application results are largely achieved irrespective of variations in the material batch.
Consistent spot welding
Spot welding with the TruDisk Pulse provides especially low-spatter and reproducible results. The diameter and depth of the points remain consistent throughout the process.
Direct copper bonding (DCB)
The TruDisk Pulse can also weld thin materials with no impact on the base. For example, copper tracks can be contacted onto substrates using ribbons or wires, without damaging the underlying ceramic.
Whatever the surface quality, the TruDisk Pulse welds copper seams with consistent quality as a result of the more stable process at a wavelength of 525 nm, and ensures that you will have highly robust production.
Laser-welded electrical contacts
With the TruDisk Pulse, you can reliably weld sensitive electronic components by yourself. With the green wavelength, you can reduce spatter by over 95% in comparison to infrared light. This means that you effectively avoid short circuits and the resulting faulty components.

With TRUMPF you have the ability to adapt your solid-state laser to your installation and operating situation with flexibility. This applies, for example, to all beam guidance components and the control. Interfaces for different optics are provided right from the start. To save costs, your beam source can supply several work stations at the same time. The TRUMPF Remote Service helps you to ensure your system remains available, anywhere and at any time.
There are many different options for the beam guidance that will enable you to create a flexible plan with your laser. The plug & play optical laser cables can be easily connected to different work stations. Here, you choose the number of fiber outlets up to a total of two. The laser power can be flexibly divided across the outlets. This allows multiple work stations to operate simultaneously with split laser power or one after the other at full laser power. The modular design means that the laser power and the number of outlets can be changed retrospectively in the field at any time.
With the laser network, you can connect one or more lasers with up to two work stations in each case. In the process, your laser either splits its power to multiple stations, or it supplies them by taking turns with full power. The overall availability of your manufacturing systems will increase as a result due to simple redundancy concepts.
In the event of an error, TRUMPF service experts will remotely access your laser via a secure remote connection. In many cases the fault can be remedied directly in this way, or the configuration of the laser can be modified in a way that permits you to continue manufacturing until the spare part arrives. This enables maximum availability for you.
Intelligent optics can be synchronized with your laser via a dedicated interface. For example, the CFO focusing optics or PFO scanner optics can be used optimally for your purposes. Programming of the processing optics is performed via the user-friendly laser control system, so there is no need for additional computers or control systems.
Intelligent optics can be synchronized with your laser via a dedicated interface. This will allow you, for example, to use the PFO scanner optics optimally for your purposes. You can easily program the processing optics via the laser control system. You do not need any additional PCs or control systems.
Processing optics and fiber optic cables can be cooled easily and conveniently using the laser cooling water. Separate cooling is therefore, not necessary.
The WeldAssist database provides you with welding parameters for various materials and focal diameters. This makes set-up easier for frequently changing laser applications.
TruControl is the quick and easy-to-use control for TRUMPF solid-state lasers. It regulates the laser power in real time in order to deliver reproducible results. Additional modules are specially tailored to the requirements of the TruFiber: The CutAssist option automatically adapts the laser parameters to the speed of the guidance system. In order to ensure that parts are traceable, the DataStore module records all quality-related data.
If external controls are present, TruControl will communicate with them via all standard interfaces. Inputs are made via the touchscreen of the operating panel or via a panel PC. You can integrate your laser into the network via Ethernet and connect multiple PCs.
The TRUMPF sensor systems mean that your production will always be both productive and cost-effective. The sensor products VisionLine, CalibrationLine and integrated pyrometers ensure stable processes by monitoring all the procedures in laser production and make a significant contribution towards your process reliability. Processing continues unimpeded during the measurement – no interruptions are required, saving you valuable production time.
TRUMPF VisionLine image processing detects features on the components and ensures that welding is always in the correct location.
The TRUMPF CalibrationLine tool checks and corrects the focal position and laser power on the workpiece at regular, individually definable intervals.
Lasers and laser systems – with us, the perfect pair. All beam sources are optimally attuned to the requirements of the TRUMPF laser systems. You can choose between numerous versions and options, resulting in a system which is precisely tailored to your task. It is, of course, also possible to integrate our lasers directly into your production lines.
TRUMPF offers you all the components you need for beam guidance from the laser to the workpiece. This also applies for various focusing optics which have proven themselves to be precise and reliable over many years of industrial use. The optics can be easily integrated – both in stand-alone processing stations as well as in complete production lines. The modular structure enables the optics to be continually adapted to the laser types and various processing situations.
Regardless of whether you are welding, cutting, ablating, heat treating, or drilling, you can count on high-quality process results with robust focusing optics from TRUMPF.
