Thermal Cycling/Thermal Shock

(Operational and Non-Operational)

Cobham Sensor Systems, San Diego has an extensive background in Functional Thermal Cycle Testing. Data acquisition is available for a multitude of parameters including temperature, DC characteristics and AC to 20 GHz. All thermal chambers utilize secondary over/under temperature protection, including dual LN2 valves. A completely independent controller operates each valve.

Cobham’s Thermal Cycling capability includes 10 Delta Design fast ramping chambers, one Blue M Dual Zone Thermal Cycling chamber, a 4 cubit foot Associated Thermal Cycling Chamber and a 32 cubic foot Envirotronics Thermal Cycling Chamber. This provides the ability to meet many different test conditions including all revisions of MIL-STD-883 and MIL-STD-202. Non-standard test conditions are also easily programmed using the microprocessor-based controllers. Event switches and chart recorders are available to meet any test requirement.

Liquid thermal shock from -65 degrees C to 150 degrees C is also available. This requirement is met with a fully programmable liquid bath test system equipped with a programmable chart recorder recording each bath and load temperature.
