Cressington Vacuum Coating Systems

Product description

This is an easy to use basic instrument for gold plating of SEM samples. It has fully variable current control, a digital process timer with pause option, a variable height sample table, a hinged top plate, and an O-ring sealed vacuum chamber. The control allows the spray current to be set independently of the gas pressure, which is adjusted separately by means of a manual leak valve. Coverage and grain size are optimized for any sample. Cool magnetron type head with 57mm diameter objective provides efficient spraying with minimal heating. The coating time is set by a timer with a digital readout and stored in memory. Vacuum status and sputtering current are displayed on the panel meter.

A modular desktop design combines the spray control unit, pumping system and thickness monitor in an area of just 400 x 600mm. It is fully integrated via a quick release all-metal coupling system. The height-adjustable specimen table will accept up to 12 pin-type tips or can be used as a platform for other types of tips and samples. A vacuum feed is provided for the optional film thickness monitor.

Chamber size: 120 x 120mm

Product description

A more advanced spray coater where the entire sequence of flushing, leaking, coating and venting is automatically controlled. Solenoid operated blow off valve allows gas pressure to automatically return to preset conditions. The coater can also be operated in manual mode if required. The spray current is set by a digital programmer and is independent of gas pressure. Sputtering currents of up to 40 mA allow the magnetron head to efficiently bombard a variety of target materials. The coating time can be set, stored and displayed by the digital timer.

Further automation can be achieved with the addition of the finishing film thickness monitor. With this installed, the desired thickness can be entered and the sputtering process ends automatically when this thickness is reached.

Chamber size: 120 x 120 mm.

Product description

The Cressington 208HR High Resolution Sputter Coater offers a real solution to the problems encountered when coating difficult samples for FEG SEM imaging.

To minimize the effect of grain size, the coater provides full control over thickness and deposition conditions. The turbomolecular entrainer pump provides the high vacuum needed for non-noble metal sputtering while having excellent gas handling characteristics. The magnetron sputtering head has the high current capability required for chrome sputtering and a source shutter for target conditioning is provided as standard.

The tilting rotating planetary stage ensures that highly contoured samples are evenly coated. This ensures that the minimum coating thickness can be applied to provide conductivity without compromising the fine details of the sample. The double height 150mm diameter working chamber provides easy adjustment of the working distance.

The built-in finish film thickness monitor allows close monitoring and reproduction of coating thickness for repeated samples.

Product description

The 108C Auto Carbon SEM Coater is a unit dedicated to the routine coating of SEM and microprobe samples, where a low atomic number conductive coating is required. Dual carbon rod source with unique current feedback control provides highly reproducible carbon coatings.

In automatic mode, the required voltage setting and flash time can be entered and displayed through the digital programmer. Manual and pulse modes are also included for coating heat-sensitive samples. The height-adjustable sample table allows the working distance to be changed.

When accurate determination of coating thickness is required, the manual film thickness monitor can be used with this coating unit and a vacuum step is included for this purpose.

Product description

High vacuum carbon evaporation provides the predictable spatial distribution and thickness needed for X-ray microanalysis and imaging of non-conducting samples. High vacuum is achieved by a 80 l/sec turbomolecular pump backed by a rotary pump. In addition to providing fast pump downtime, it has the advantage of not requiring water cooling or a long warm-up period. The vacuum is continuously monitored. Carbon is dual-evaporated from the carbon rod source with manual, pulsed or automatic mode operation. The thickness can be monitored by the optional film thickness monitor.

For highly contoured samples, the optional motorized rotating planetary stage with tilt greatly increases sample coverage. All four sample holders are interchangeable and can be configured to fit most types of samples or metallurgical setups. Up to 24 pin tips can be coated at one time. The stage includes a lower working chamber. This allows the working distance to be changed. The long working distance with the standard 150mm diameter x 150mm high chamber with 0° tilt can be used for uniform coating of flat polished microprobe samples, while the short working distance with the high tilt is used for topographic samples.

This is the most advanced carbon coater with wide applications for TEM, SEM and microprobe techniques. The basic turbo carbon coater can be equipped with different accessories to make it suitable for SEM (with high vacuum for microprobe or polished substrates, or low vacuum for coarse or granular substrates), TEM (for support films, shadowing, aperture cleaning, glow discharge, etc.) or both.



The modular design allows quick changeover between a variety of applications with optimized operating conditions:

Voltage controlled wand source provides multiple evaporation capability Automatic evaporation control provides ease of use in a busy environment Low cost thickness monitor provides reproducible results 80 l/s turbo pump in a 150mm chamber provides a very fast emptying Reduces operating costs by not having a diffusion pump, water cooling or liquid nitrogen
