Laser welding is a very gentle welding technique, as the heat input takes place in a locally very limited area. In this way, it is possible to reliably connect critical components with one another in a materially bonded manner, without the parts annealing. With laser welding, the two welding partners are joined together with as few gaps as possible in order to then weld them together (e.g. press-fit zones such as EloPin® puzzled at any feed or distance). The background to this is that no additional material is generally used in laser welding. Exception for build-up welding or repair welding of e.g. broken tool parts such as punches or cutting plates or injection molding tools for abrasive plastics with glass fiber filling. Materials - almost all metals: e.g. • non-ferrous metals (Cu, CuSn0.15, CuSn6, CuNiSi, ...), • titanium, • steel, stainless steel (1.4301, 1.4404, ...), • spring steel (1.4310), • electrical steel (M235, M270, NO20, NO30, ...), …

The KLN QSW 400 L is a modular laser welding machine. The advantage of the modular structure is that the central laser welding machine can remain unchanged in the various welding tasks and only the housing and its frame structure must be adapted to the actual welding task. Thus, a well-tried laser welding unit can always be used. Moreover, adaptions to other welding tasks can be easily integrated, e. g. with rotary table, tool carrier, conveyeor or sliding table. Laser: Water-cooled diode laser with 300 W optical output power Wave length 980 nm ±10 nm Pilot beam at 650 nm ±15 nm (<1 mW) Optical fibre suitable for wave length 780-1030 nm Focal distance of collimation 58 mm Focal distance f-theta objective 635 mm Operating distance 728 mm Operating field (scan field) 415 mm x 415 mm

Initial Situation: Inspection of a laser weld seam for pores and geometrical anomalies The production of a client in automotive industry is subjected to extremely stringent quality requirements. This is valid particularly also for the precision of laser weld seam of fine mechanical work. 100% inline supervision is required for the following task: A laser weld beam (width ca. 200µm) has to be verified with respect to the presence of pores and geometrical anomalies. Camera inspection performed until now turned out to be not stable. Therefore the client is forced to implement an improved monitoring process. The challenge The resolution required amounts to 4µm. The high gloss finished material and glossy laser weld seam may give rise to reflections, and the space for installation is restricted. A low form factor for the monitoring equipment is imperative.

Rotationally symmetrical driving gears in a line producing for automotive industry are mutually connected by electron beam welding. The camera inspection carried out until was not able to assess the quality of the weld seams at the required precision. Non-contact laser measurement system Particular Challenge: As the welding seams show a high reflectivity and are located at a position hard to access, inspection is difficult, all the more so as they dispose of a width of only 500µm. Therefore it is quite a challenge for the laser measurement system. The QuellTech solution: A QuellTech Laser Scanner Q4-5 with extremely small shape factor and high resolution proved to be perfectly suited for this application. In order to suppress reflections from elements in the surroundings, a particular algorithm has been integrated. Furthermore, this laser measurement system features a particularly adapted laser wavelength and an ultrafine laser line.

In an environmental simulation, assemblies are subjected to defined environmental conditions to validate their behavior under those conditions. The variables of an environmental simulation test include climatic aspects such as temperature (cold, heat), the air conditions (humidity, wetness), mechanical influences such as dust, vibration, vibration or impacts, and corrosive environmental effects such as salty lift (salt fog). As an environmental simulation laboratory, we simulate these environmental conditions in our climatic chambers and climatic chambers, creating real conditions to investigate the long-term behavior of the test specimens in reality. Environmental simulation and thermal shock testing laboratory for electronic assemblies and printed circuit boards We specialize in performing environmental simulation and temperature shock testing of electronic and mechanical assemblies. With over ten years of experience with the requirements of the automotive industry and medical

We are specialist in strain gage strain measurements on printed circuit boards and all other components. We carry out the application of strain gages and determine for you the actual stresses that occur, or the strain (also strain-rate) on a specific or several components in the manufacturing or assembly process. We perform our DMS measurements with certified measurement technology and according to the specifications of IPC/JEDEC-9704A. Expert advice from TEPROSA When measuring strain, in addition to many factors such as the appropriate measurement technology, it is also important to rperform the strain measurement correctly and to ensure that the sensors record the forces correctly. To ensure that the deformation of an object is correctly determined, it is therefore crucial to select the right strain gauges (also known as measuring strips) and to place them in the correct position on the measured object.

Mechatronic integrated devices or molded interconnect devices (injection-molded circuit carriers) are spatial electronic assemblies – so-called 3D-MID. A special process is used to apply metallic conductor tracks to a specific substrate material (often plastic), thus creating three-dimensional assemblies that also serve as circuit carriers. These spatial electronic assemblies are manufactured using 3D-MID technology and, compared to conventional assemblies, enable the integration of electronic, mechanical, fluidic, optical and thermal functions. The resulting additional benefits represent advantages that cannot be realized with two-dimensional circuit carriers (printed circuit boards).

With the help of the 3D-MID process, plastic parts can be metallized not only over the entire surface, but also selectively. To do this, the plastic part is activated with a special laser at the points that are to be coated (this is referred to as laser activation or laser direct structuring). The additives contained in the plastic directly under the plastic surface are “exposed” by the laser treatment. In a chemical bath, copper particles can then be deposited specifically only on the activated surfaces. Other metals, e.g. nickel, tin or gold, can then be deposited onto the starting layer of copper. In this way, a selectively coated plastic part is obtained. MID technology thereby makes it possible to selectively coat two-dimensional and also three-dimensional plastic parts and use them, for example, as circuit carriers for electronic or mechatronic assemblies. With the LPKF-LDS process

We offer laser direct structuring (LPKF-LDS process) for the production of 3D-MID (so-called three-dimensional circuit carriers) as a service in Magdeburg. 3D-MID stands for Mechatronic Integrated Device (or Molded Interconnected Devices). The MID technology makes it possible to use three-dimensional plastic parts as circuit carriers for electronic or mechatronic assemblies. The LPKF-LDS process is one of the technologically leading and at the same time most economically interesting process for the production of 3D-MID. The LPKF LDS process represents the central process step. The process was developed and patented by the company LPKF Laser & Electronics AG in Hanover.

3D-MID are three-dimensional, spatial circuit carriers. The abbreviation MID stands for Molded Interconnect Device, or also for Mechatronic Integrated Devices. The term extension Mechatronic Integrated Devices as opposed to Molded Interconnect Devices (origin Molded = injection molded) is increasingly being used, since the three-dimensional basic bodies are no longer manufactured exclusively through the use of injection molding technology and no longer exclusively from plastic.

Baking varnish is a special joining technology for sheet metal packages. After the individual lamellas have been cut, electrical steel with a baking varnish coating is baked into a sheet metal package in a two-stage temperature step. The result is a full-surface, solid connection between the individual sheets with complete insulation. Sheet metal packages manufactured in this way have high precision and perfect magnetic properties. Advantages of the Backlack process: The Backlack process offers several advantages over alternative packaging processes, which we will discuss in detail below. Precision – Sheets coated with baking varnish are baked over the entire surface. This means that even delicate slats can be assembled precisely.
