Thermal Fracture and T Thermal Shock Test by Study of Thermal Stres JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally.
JEDEC standards and publications are adopted without regard to whether or not their adoption may involve patents or articles, materials, or processes.
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. No claims to be in conformance with this jesd22-aa106 may be made unless all requirements jeec in the standard are met.

The specimens under test and the fixtures holding those specimens during test. 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. The largest load for which the worst-case load temperature meets the timing requirements see 4.
The temperature sensor located and calibrated to indicate the same temperature as at the worst-case indicator specimen location. NOTE The worst-case indicator specimen location is identified during the periodic characterization of the worst-case load temperature. The device or individual piece being tested.
Thermal Shock Test (TST)
The elapsed time measured from removal of the load from one bath until insertion in the other bath. The temperature of jesd22-a06 specific specimen as indicated by a thermocouple imbedded in the body and located at the center of the load. The thermal capacity and liquid circulation must enable the working zone and loads to meet the specified conditions and timing see 4. Worst-case load temperature shall be continually monitored during jexec by indicators or recorders reading the monitoring sensor s.
The worst-case load temperature under maximum load conditions and configuration shall be verified as needed to validate bath performance.
The load shall then be subjected to the specified condition in Table 1 for a specified number of cycles. 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.
However, if the number of interruptions for any given test exceeds 10 percent of the total number of cycles specified, the test must be restarted from the beginning.
The load may be transferred when the worst-case load temperature is within the limits specified in Table 1. 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 shall reach the specified temperature within the dwell time.
