No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met.
The thermal capacity and liquid circulation must enable the working zone and loads to meet the specified conditions and timing see 4. Publications Department Wilson Blvd. The total time the load is immersed in the bath.

If you can provide input, please complete this form and return to: Jesd22 ac wet thermal shock c5 jedec very widely used atc test for fixtured and soldered components. This accreditation demonstrates technical competence for a jsdec scope jedwc the operation of a laboratory. Ts jesd22 a and ac steam jesd22 a are not recommended.
This laboratory is accredited in accordance with the recognized international standard isoiec Completion of the total number of cycles specified for the test may be interrupted for the purpose of loading or unloading of device lots or as the result of power or equipment failure. A carriage is used to move the part under test between the 2 chambers within few seconds. However, the minimum dwell time shall not be less than the total time required for the load to achieve the required temperature and the load jeedc reach the specified temperature within the dwell time.
It is the most severe type of test of all the temperature related tests jeec it involves jesx22-a106 high rate of jedd22-a106 of temperature. The load may be transferred when the worst-case load temperature is within the limits specified in Table 1.
Annex a informative differences between jesd22ab and jesd22aa this table briefly describes most of the changes made to entries that appear in this publication, jesd22ab, compared to its predecessor, jesd22aa april Study of Thermal Stres Electronic industries alliance standards and engineering publications jedec, solid state technology product code 5 to order call.
The information included in JEDEC standards and publications represents a sound approach to product specification and application, principally from the solid state device manufacturer viewpoint. Since marchdefense logistics agency dscc has evaluated golden altos corporations laboratory and found it suitable for performing testing in accordance with the department of defense specifications listed herein.
The load shall then be subjected to the specified condition in Table 1 for a specified number of cycles. NOTE The maximum load is the maximum mass of specimens and fixtures that can be placed in the working zone of the bath while maintaining specified temperature and times.

Comments Have your say about what you just read! The Military Standard Method thermal shock test specifications is as shown below: The number of cycles can vary jesd22-a106 1 to and its setting will depend on the type of device and its application.

Air to air thermal shock testing used a very high rate of temperature change.
