Challenges in handling highly filled and abrasive materials When it comes to electrically conductive materials, we are dealing with dispersions. They are generally referred to as electrically conductive adhesives, silicones or inks. The materials are divided into different areas: Epoxy resins, polyurethanes, silicones and acrylates. Epoxy resins in particular stand out due to their processing and material properties. They are … Read More
Spraying of abrasive soldering paste
ViscoTec has proven high expertise particularly in complex dosing environments. ViscoTec´s brand preeflow shows the capability to operate reliable, extremely precise and repeatable for various applications in many industries. With the help of the precision volume dispenser “eco-SPRAY” preeflow explores new paths. Soldering pastes are pasty mixtures of solder powder and flux agents, which enable an accurate soldering of metals … Read More
Dosing of soldering paste without technical limits
With the introduction of a new product at the B.B.W. Bayrischen Bohrerwerke GmbH in Büchlberg 2012 the requests to the dosing of soldering paste were even rising. A compact application with constant, precise and reproducible results with highly filled soldering paste were in demand. At this point preeflow came into play. Handling solder pastes with high viscosity, in this case … Read More
In the beginning there was pitch.
Most people today associate adhesives with chemistry and regard them – like the industrial production of chemical goods – as a relatively recent invention. However, at over 180,000 years old, this supposedly modern joining technology is at least as old as mechanical joining. Even “Ötzi”, the Stone Age man who died in the Ötztal Alps around 3340 BC and was … Read More
Pimp my Pump
The standard is to use snow tyres for motor vehicles to receive optimum performance of your car under harsh weather conditions. The tyre for the cold season is made out of a different elastomer combination which is responsible for optimum grip and minimized wear at winterly road conditions. Comparably to this we offer a special elastomer combination for our products … Read More
Perfectly dosed thermal pastes
In power electronics thermal pastes are for example used for cooling of processors or other construction elements. Even the smallest of cavities on the surfaces of the components often downgrade the heat transfer enormously. The pastes exactly fill these cavities and optimize the transmission characteristics of the cooling elements. The thermal pastes are usually high-filled substances, so called ‘Gap Fillers’. … Read More
