Today, the automotive industry accelerates electronic multi-functions. According to this trend, safety standards such as ISO26262 and IEC61508 require high environmental stress that is generated by thermal shock chambers for higher reliability of vehicle equipments.
Three large-capacity chambers have been added to the TSB series of Liquid to Liquid Thermal Shock Chambers.
Compared to the air to air thermal shock type, the liquid to liquid thermal shock type applies higher stress on the specimen, and shortens a test time.
In addition, the weight load has been increased in accordance with the larger specimen basket, thereby enabling support of large specimens.
The in-vehicle inverter can be evaluated as a fully assembled product or with components mounted; it makes it possible test specimen while current is carried. As a result, this model offers an environment similar to actual conditions in the reproduction of heat stress during failure mode analysis such as of BGA mounting.
It is available from three test area capacities: approximately 10 liters, 15 liters, and 30 liters.
To reduce brine consumption, the airtightness of the test area has been increased to prevent vapor leaks and evaporation has been prevented.There are also other mechanisms to recycle brine after separating water by the filter for. The Galden® fluid hardly leaks. For support status of silicon oil and Fluorinert, please contact our sales representatives.
An air cylinder reduces vibration to the specimen. A new drivel mechanism, when inserting the specimen into the water bath, is being used to control excess stress to the specimen during transferred between the hot chamber and cold chamber.
Basic control method is common by using the same interactive touch panel instrumentation as that of the standard Liquid to Liquid Thermal Shock Chamber.
