The FAPI-KLETT self-adhesive hook-and-loop coating allows a very fast change of abrasives with a wide range of grit sizes. The self-adhesive FAPI-KLETT Velcro is simply glued onto the grinding machine’s plate, so that the abrasive with the desired grain size can then be applied.
The FAPI-KLETT self-adhesive Velcro pads are used on all commercially available grinding machines.
Tungsten layers are components of the thin-film transistors used in TFT-LCD screens. They are used wherever large screen formats, particularly high image definition and optimized contrasts are needed. But tungsten is also used as a diffusion barrier and a conductive connector in the microelectronics industry.
Using the world's largest hot rolling mill for refractory metals, Plansee is able to produce the largest tungsten sputtering target on earth. The benefit to you of large formats: The coating process is more stable and the deposited layers are of higher quality.
Thanks to the special forming processes Plansee's tungsten sputtering targets have a density of almost 100 %. As a result, your process benefits from a particularly high level of conductivity and time savings due to the excellent sputtering speeds.
Spare parts include for example chambers, filaments, arc slits, holders and many other parts. The pare parts are made of graphite, molybdenum, tungsten and alloys. They are extremely durable and long lasting and therefore save money and maintenance time.
100 or more Plansee components are at work in every beam path. They ensure that the ions are generated efficiently and guided precisely and free from impurities along the beam path to the wafer. For customers in the semiconductor industry, Plansee spare parts are increasingly becoming more than just spares. Taking the equipment manufacturer's original spare parts as starting point, Plansee optimizes the geometries and material compositions. The benefits to you:
— Simplified component installation and removal
— Longer service lives
— Lower cleaning costs
— Reduced maintenance work
— Reduced downtimes
Molybdenum and tungsten crucibles from Plansee are the perfect vessels for melting and solidifying the single crystal. The formed crucibles have particularly thin walls combined with excellent creep resistance. The outstanding purity of the crucibles prevents any contamination of the single crystal. Even the most aggressive sapphire melts cannot do any harm.
Plansee produces large numbers of formed molybdenum and tungsten crucibles and supplies them in all commonly used dimensions. They are successfully used by all the major manufacturers and numerous end customers worldwide.
