SMD fuses: Reliable protection directly on the PCB

SMD fuses offer a compact and precise solution for primary and secondary protection directly on the printed circuit board. The UMF 250 series fuses are fast-acting SMD fuses that protect electronic systems from overcurrents and short circuits. The UMT 250 fuses are characterised by a high breaking capacity.

Thanks to their very small size, they are ideal for placement machines. The UMZ 250 miniature SMD fuses, on the other hand, offer maximum switching capacity with the smallest installation dimensions and enable easy replacement after the soldering process.

Chip fuses: effective and compact protection

SCHURTER's chip fuses have been specially developed for secondary circuits and provide precise and low-loss overcurrent protection. Thanks to their solid construction, they are particularly resistant to vibrations and pulse loads.

With six different types in chip sizes from 0402 to 1206, the fuses provide compact and effective protection in the event of a fault. The USI 1206 chip fuse is the only one on the market with VDE approval. The gold-plated SMD contacts also make the chip fuses particularly suitable for storage and have a positive effect on contact quality.

The chip fuses are suitable for a wide range of applications, particularly for mobile and battery-operated devices in sensor technology and industrial electronics. They are also suitable for lead-free soldering processes, as they are both halogen-free and RoHS-compliant.

Compact components with high performance from APEM

The trend towards miniaturisation continues and compact applications with high safety requirements are in ever-greater demand. With the Ultramec series, APEM is responding to this trend and offering single-pole and 2-pole short-travel keyswitches that are particularly suitable for safety-critical functions in industrial remote control or for other devices with limited space.

The Dualmec switch from the Ultramec family is currently the smallest 2-pole switch on the market. The switch was specially developed to increase safety in hand-held devices and devices with limited space. Despite the 2-pole design, the switches are suitable for demanding applications.

The advantages of the small SMD component:

• Increased safety through double confirmation
• Compact
• Numerous design options with standard caps
• Easy alignment of front and printed circuit board with the help of sliding caps
• Precise switch positioning with positioning pins

Drag soldering: Reworking with Weller

Reworking printed circuit boards is a necessary evil that often cannot be avoided. This makes it all the more important to have good soldering and reworking tools available at the workplace. Some components require a lot of time, training, skill and dexterity. A high number of pins and a fine grid can be a challenge even for experienced soldering technicians.

Point-to-point rework and soldering is a good process if only a few connections need to be reworked. If a large number of connections need to be soldered or the entire device needs to be moved and soldered, point-to-point soldering is too time-consuming.

An alternative to this is drag soldering, which produces very even solder joints. It is also very fast and easy to perform with a little training. However, it should be noted that drag soldering requires external liquid flux. This makes the cleaning process more complex to ensure that no flux residue remains on the assembly.

Reworking always involves effort and costs. However, the right technique and training, together with high-quality soldering equipment, ensure high quality, high yield and low costs for the end product. That is why we rely on the high-quality products from Weller.

Smart Tweezers from ideal-tek: redefining measurement and precision

Smart Tweezers redefine measurement and precision: they significantly simplify the testing and troubleshooting process. The Smart Tweezers from ideal-tek meet the highest standards and are as accurate as classic LCR meters. Thanks to their compact and ergonomic design, they are lightweight and can be operated with one hand – whether you are right- or left-handed.

With the Smart Tweezers, you can measure the capacitance, resistance, inductance and much more of electronic components. In addition, the device automatically recognises the component to be measured and selects the correct settings.

The perfect addition to the Smart Tweezers is the matching display. This allows you to view your data in real time and save it on a micro SD card or via the cloud. The display has 16GB of memory and runs on Android. The design of the display enables it to be used in the field or at the workbench.

A perfect fit for anyone who works with electronic components: easy to use, efficient and accurate.

Video microscopes for quality inspection from Kern

For quality inspection of manufactured components, we recommend high-resolution video microscopes. The Kern OIV-3 was specially designed to optimise digital stereomicroscopy. As a result, the video microscope offers a well-thought-out complete solution for axial optics and enables direct and uncomplicated display of your samples on the screen.

The large working surface and the large display enable observation, analysis and documentation, even in industrial applications. An additional monitor can be connected via an HDMI interface. This allows live observation to be carried out on two devices operated in parallel.

The included LED incident light illumination allows you to optimally illuminate your sample, and the zoom wheels with integrated click-stop allow you to precisely select the magnification level. This makes it easy to calibrate the documentation functions in the software.
