The Form A locating pins can also be used as limit stops or fixture feet. Advantages: Cerazur is extremely impact and bend resistant. The basis of this material is zirconium oxide. It is a composite metal-ceramic material. Drawing reference: Form A and B: cylindrical locating pin Form C and D: flattened locating pin

COLD LASER PERMANENT MARKING Cold laser marking refers to marking and treatment carried out with minimal thermal stress. Laser beam concentration allows direct marking without generating heat into parts, avoiding any burning or deformation. This permanent marking doesn’t alter the material and is an ideal solution for identification marking on soft materials and sensitive components. ULTRA-HIGH-DEFINITION MICRO MARKING Gravotech has developed green laser heads that guarantee small and fine markings. It offers an extremely thin spot size of 20 μm for micro markings with exceptional resolution while limiting thermal stress on the material. Small 2D Datamatrix, detailed logo, precise removal of thin layers of coating. MARK THE IMPOSSIBLE WITH THE GREEN LASER This range uses a 532 nm wavelength to mark materials that would not normally react to infrared wavelengths: from rough to the most transparent plastics, reflective metals (copper, silver, gold), ceramic, cardboard, wood.

Various methods of assembly exist to bind ceramic to metal. When it comes to make an assembly that can resist to mechanical stresses and/or high temperatures, be vacuum leak tight and withstand corrosive environment, high temperature, braze sealing is essential. Applications Ceramic-to-metal brazed assemblies are particularly suited for use in airborne electronics for the aerospace, defense devices, medical and analytical instruments,high-energy physics, high vacuum equipment, the nuclear industry... We offer customized ceramic to metal brazed assemblies such as for instance : high-voltage feedthroughs for the mass spectrometry, hermetic packages for airborne electronics or sensors for the oil industry, high-voltage hermetic connectors for the nuclear industry, high-voltage insulators for electron tubes.

Ceramic components offer significant advantages over metal and plastic parts. They retain their full dimensional stability at high temperatures – well above 1000°c. They show a high-wear resistance. They are extremely good electrical insulators. They do not outgas in vacuum environment. Ceramics are inert materials and are resistant to many gases and chemicals. In addition to single ceramic products, Microcertec can also offer hermetic brazed assemblies - glass to metal and ceramic to metal. Applications Applications for components made in technical ceramics in the field of aerospace are very diverse : accelerometers gyroscopes vision devices antennas ignition devices pressure sensors spark plugs magnetic traps Products Ceramic products are also very diverse : 3D interconnection devices vibrating components coil formers insulators membranes magnets Materials Every kind of technical ceramics will demonstrate a benefit for use in aerospace applications : aluminium oxide...

There are numerous benefits to use ceramics in the field of scientific and medical instrumentation. Ceramics resist to severe environments, and demonstrate excellent properties of electrical insulation, low thermal expansion and high corrosion resistance. Also, they are clean materials in view of their high purity levels, no open porosities and biomedical inertness. In addition to single ceramic products, Microcertec can also offer ceramic to metal brazed assemblies that are hermetic in vacuum and ultra-high vacuum - UHV. Applications In the analytical scentific and medical equipment industry, ceramic components are primarily used in analyzing, diagnosis, vision and therapy systems : mass spectrometers MNR spectrometers gas analyzers particle accelerators electronic microscopes imaging equipment blood analyzers neurosurgery instruments endoscopes Products Precision grinding allows to achieve extremely tight dimensional tolerances and very diverse geometries.

Laser ablation technology helps the engineer to develop circuit carriers which cannot be manufactured with chemical etching technology. This kind of product results from combining the technologies of precision-grinding of ceramics and laser ablation of metallised thin-film layers. We name this concept "three-dimensional interconnection circuit or CI3D". Principle The laser structuring consist to etch directly a metallization layer deposited on a ceramic carrier with a laser beam without using a mask. This is called laser micromachining or laser ablation - because metal is ablated. Laser ablation allows patterns to be etched directly on the ceramics substrate, very rapidly and beam displacements to be programmed limitless. Equipment Solid-state lasers are mostly used for micromachining applications because they feature precision, speed and selective etching. We currently use a Nd :YAG laser with 60 W output. It enables us to etch thin-film metallised layers with thickness of up...

Microcertec manufacture ceramic reflectors for lasers and IPL systems. We offer customized reflectors that are primarily manufactured from high-reflectivity alumina and subsequently glazed over in order to guarantee leak-tightness and protection. The base material - reflective alumina - was developed specificaly for this application. It offers a high reflectivity from visible to near infra-red. Reflectors are machined / ground against customer's drawing. Quantities range from prototype to production quantities. Glazing protects the surface in preventing adhesion of impurities and primarily ensures leak tightness of the reflectors. Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power. They also have the advantage of being more resistant to temperature variations and erosion from cooling fluids, hence leading to extended operating life. Applications The following applications require ceramic reflectors in order to ensure a high...
