Long Business Description:

Hot Disk AB is dedicated solely to facilitating its clients’ thermal transport property measurements. Utilizing the groundbreaking and recently ISO-certified TPS (Transient Plane Source) technique, Hot Disk instruments accurately ascertain the thermal conductivity, thermal diffusivity and specific heat capacity of a vast range of materials from single transient recordings. We have claimed considerable market share from competitors employing older and more limited techniques in recent years.
Hot Disk AB develops and provides equipment for measuring and testing thermal conductivity, thermal diffusivity and specific heat capacity. With our equipment, testing thermal properties is easy, fast and non-destructive.
Knowing the thermal properties of materials or devices is crucial when designing any application where heating or cooling is a factor. Being able to readily acquire this information is important for designers, engineers and scientists alike.

Examples for Applications:
Anisotropy: Modern batteries (Li-Ion) have drastically different thermal ¬conductivities in different directions. Simple and accurate ¬measurement procedure with Hot Disk sensors. Hot Disk can perform anisotropic measurements on modern, Li-Ion batteries with a regular stack structure. The stack structure can be either cylindrical stack, or a plane stack structure.

Long Business Description:

The SURAGUS GmbH develops, manufactures and sells eddy current-based testing technology for innovative testing tasks. The company uses new technological opportunities due to advances in signal processing, the availability of more powerful computing technologies and possibilities of new manufacturing and miniaturization methods. Applications are amongst others quality control of structured and unstructured functional layers, quality assurance of carbon fiber materials and classic conductive materials. The company is a spin-off and licensees of the Fraunhofer IKTS Dresden.
The eddy current method utilizes local conductivity variations of the test objects for the characterization of correlated quality characteristics such as thickness, conductivity, homogeneity and purity or physical changes. The complex eddy current signal contains various information about the test object which can be separated in many cases with simple or complex algorithms. Our eddy current testing technology is based on a powerful eddy current electronics with a frequency range from 10 kHz to 100 MHz, which is combined with different sensor concepts depending on the application.
Primary advantages:
Contact-free
Fast (EddyCus Systems measure at a rate of 50.000 measurements per second)
Suitable for automation
Broad portfolio of sensors for different applications

Applications include:
Contactless Conductivity measurement of functional thin films (e.g. TCOs, CNTs, Metallization, Silver-Nanowire)
Non-contact Orientation testing and flaw detection for Carbon fiber composites (undulations, Impacts, gases, thrust faults)
Contactless weight determination in many carbon fiber materials
Determination of gradients of super-alloys
Layer thickness measurement of thin films and coatings from 5 nm thickness
Mapping for errors in conductive layer system (cracks, voids, delaminations, etc.)

Thermic Edge Ltd, East Sussex, UK
Address: 30 Brunel Road,, St. Leonards on Sea, East Sussex TN38 9RT, UK
Long Business Description:

Thermic Edge Ltd is a design and manufacturing business with specialist knowledge of every kind of laboratory heating applications, from basic elements or sample heaters, to complete hot stages with rotation, manipulation and substrate bias. We have standard ranges of stand alone sample heaters and flange mounted sample heaters with feedthroughs incorporated. Our sample heaters and hot stages are used in a very wide range of laboratory applications including, PVD sputtering, thermal deposition, e-beam, CVD, MOCVD, PLD, ion beam implanters, carbon nanotubes and graphene growth.

Thermic Edge Ltd can offer a range of sample heater controllers to accurately control any kind of hot stage or sample heater. Heater controllers are fitted with Eurotherm PID temperature controllers as standard, but we can incorporate any type of controller that our customers might specify.

Thermic Edge Ltd  also has a range of high temperature laboratory vacuum / inert atmosphere furnaces with graphite hot zones. These furnaces can heat a crucible or wafer to 2100C. All furnaces are plc controlled and are fully interlocked, with simple one button pump / vent operation. A choice of PID temperature controllers enables a high degree of control and programmable temperature ramping and cooling functions. Dual zone temperature control on flat wafer furnaces gives very high uniformity across the substrate.
We can offer a complete range of technical ceramic materials and components including Shapal, Macor, Alumina, Boron Nitride, Aluminium nitride and Quartz. We can also offer CVD produced ceramics such as pyrotytic boron nitride PBN and pyrolytic graphite.
