1 VTS³ and VCS³ Stress Screening Systems More Power for Maximum Quality Assurance

2 Tailor-made for your product: Our proven testing methods Thermal and climatic conditions can affect the production, storage and use of your products and therefore negatively influence their functioning, properties or service life. It is essential for the support of your product development and quality assurance to test products for possible early failure. Real test conditions Advantages of ESS Environmental stress screening (ESS) refers to a method in which test specimens are exposed to climatic, thermal or mechanical stresses in order to provoke early failures. To cite just one example, this can uncover weaknesses in design, material or production of electronic modules. ESS makes it possible to sort out unreliable systems already during production testing. It has become established as a standard method for improving quality and contributes crucially to the extension of the functional lifetime of products. Higher quality, greater reliability and longer service life of the products Minimization of risk (even for new products) Fast feedback in-house rather than from customers Cost reduction because customers do not experience product failures during the warranty period Increased customer satisfaction Reduction of follow-up costs The longer flaws are ignored in the life cycle of a product, the more expensive the follow-up costs for rectifying them become.

3 VTS³ and VCS³ Stress Screening Systems: Impressive Technology More power The VTS³ and VCS³ temperature and climatic testing systems fill the gap between our proven temperature and climatic testing systems in the VT³ and VC³ range and our shock test systems. With test space sizes from 190 to 140 litres and a temperature range from C to C, we are able to meet nearly all customer requirements. The VCS³ model series implements common climatic testing standards. Preferred rates of change are K/min, 10 K/min and 1 K/min. For special applications, we offer test systems up to 30 K/min. Whether in production, research, development or quality assurance do not leave the functionality of your products to chance, entrust it to us. 3

4 Thought through: Equipment that unites function and design Test space door The high-quality insulated test space door allows access to the entire cross-section of the test space. Special circumferential profiled seals and the self-tightening one-hand door lock guarantee optimal sealing of the door. Test space The corrosion-resistant test space is produced from high-quality stainless steel and welded vapour tight. Smooth surfaces, rounded corners and embossed side walls to accommodate shelves guarantee easy cleaning of the test space. Water reservoir The VCS³ climatic test system is equipped with an integrated and easily accessible water supply tank. The water level is reliably detected by means of two sensors. If refilling is required, the user is informed via the colour touchpanel. 4

5 Temperature monitoring An independent, adjustable t min /t max temperature limiter protects the test specimens against thermal overload (in conformity with EN , 2006). A safety temperature limiter is additionally installed to ensure that the test system does not become overheated. Stainless steel entry ports Models of all sizes are equipped as standard with two stainless steel entry ports (approx. 0 mm on the left and approx. 12 mm on the right) for introducing measurement and supply connections or additional equipment. The stainless steel construction prevents intrusion of moisture into the insulation even under extreme climatic conditions of 98% RH. Psychrometric humidity measurement (VCS³ only) The humidity measurement system is based on the psychrometric measurement principle and works with a continuously wetted, easily accessible wet temperature sensor. This type of wetting leads to self-cleaning of the sensor and thus to a tremendous extension of service life. Other humidity measuring systems are optionally available.

6 Convenient accessories: Lighten your work Because of our long experience with stress screening systems, we can offer you a large selection of options, modifications and special accessories. Our goal is to satisfy the customer s requests with tailor-made, flexible solutions of the highest quality. Here is a selection of our optional special equipment: Notch port Facilitates loading: The notch port on the door frame The door frame can be optionally provided with a notch port. This facilitates the introduction of measurement and control elements and makes it possible to load the test space with already connected test specimens. Compressed-air dryer Reliable drying: The space-saving compressed air dryer The compressed-air dryer supports the dehumidification process in the test system. It enables generation of extremely dry air, thus reliably avoiding condensation in the test space. The optional compressed-air dryer is included in the equipment attachment for units up to K/min. Telescopic extension drawers Intelligently modified: Telescopic extension drawers The test space can be optionally equipped with telescopic extension drawers. The drawers are completely made of stainless steel and can each support test specimens up to 30 kg. The telescopic extension drawers can be pulled out up to 80% of their length. The insert shelves included as standard equipment are not needed with this modification. 6

7 Colour touchpanel and S!MPATI*: Communication with a system More control in a shorter time With its menu-driven user interface, the removable 8 colour touchpanel coordinates and monitors the tasks of the individual service components. Process sequences, system conditions and other process images are presented as graphical, self-explanatory pictograms. This makes use even more intuitive. Up to 100 testing programs can be easily and securely created, stored and reactivated. The desired functions are initiated with one touch. The standard: The 8 colour touchpanel The system is compatible with the S!MPATI* simulation management software. S!MPATI* sophisticated simplicity The S!MPATI* computer-assisted simulation management software is the optimal system for using and controlling testing and production systems. Your data is seamlessly documented and graphically evaluated. Easy operation: The 3. colour touchpanel (option) With S!MPATI* you can: control test and process flows more easily store and evaluate measurement and process data with clearly presented graphics easily create convenient test programs with a graphical editor link up to 99 systems to one another optimally utilize lab capacity with an easily understood time management system Comfortable control: S!MPATI* (option) 7
