TSA – Air to Air Thermal Shock Chambers

TSA are the thermal shock chambers air-to-air type of chamber. This chambers are desired for testing different products to rapid temperature changes. This kind of tests are used widely in automotive industry, in production of electronics devices and components or for special products. Thermal shock tests are one of best known methods for quickly revealing defects of electronic components such as PCB boards.
New version of this chamber family is equipped with new type of controller – it has the same functionality as for climatic test chambers Platinous J series and BenchTop chambers S and L. Those controllers are equipped as a standard with Web Manager function which allows for monitoring and controlling the chamber by using local network or Internet.

Features

• Available capacities from 40 to 300 liters,
• Possibility for working in two- or three zones (depends of the model),
• Temperature range from -70 to + 200 °C,
• Water-cooled or Air-cooled refrigeration unit,
• Microprocessor controller Instrumentation with color Touch Screen,
• Built-In network server for remote monitoring and control by using internal network or Internet,
• USB Interface used for transferring recorded data to the PC and uploading and downloading the tests,Software Pattern Manager Light for PC for making tests patterns and transferring to the chamber by using the USB port,
• New patented, refrigeration system – possibility for working in ECO mode which is saves energy.

Explanations

Meanings of the types of chambers:

• Type A – air-cooled refrigeration system,
• Type W – water-cooler refrigeration system,
• Type A/W – air-cooled or water-cooled – to be chosen by the customer.

Shock temperature – the temperature, which tested objects should obtain after changing from cold chamber to hot chamber (and vice versa). The preparation temperatures are regulated in wider range:

• Temperature in hot chamber +205 °C,
• Temperature in cold chamber -75 °C.

Recovery time:

Recovery time is most important parameter for thermal shock chambers. It is the time which is needed to achieve the shock temperature by the object after changing between hot and / cold chamber. In order to unambiguously determine this time, it is necessary to provide the following data:

• Shock temperature,
• Temperature preparation before performing shock in hot and cold chambers,
• The mass and type of the tested object (samples), which is needed during estimating their thermal capacity – a generally accepted standard is to giving this data for integrated circuits in a specific type of housing – for example, 20 kg integrated circuits in plastic housings.
