If the change to a concept involves any words added or jeesd22-a106 excluding deletion of accidentally repeated wordsit is included.

The temperature sensor located and calibrated to indicate the same temperature as at the worst-case indicator specimen location.

Jedec standard stresstestdriven qualification of integrated circuits jesd47g revision of jesd47f, december march The parts are then exposed to an extremely low or high temperature and, jrsd22-a106 a short period of time, exposed to an extremely high or low temperature, before going back to ambient temperature.

Leave us a comment in the box below. 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. In Liquid to liquid systems, a two vat system and a mechanized basket arrangement is used to move the part under test between the hot and cold sides of the equipment.

By downloading this file the individual agrees not to charge for or resell the resulting material. Electrical testing of the samples to the part specifications must also be performed to detect electrical failures due to the test.

Suite Arlington, VA Fax: Thermal Shock is performed to determine the ability of a part electronics devices, electronic products, etc to withstand sudden changes in temperature.

Table 2 — Physical property description of perfluorocarbon fluids. Join the electronics events to enhance your knowledge and network with other professionals in this industry. There are 2 types of system testing used i. Fully enclosed thermal shock test chambers are normally used to avoid unintended exposure to ambient temperature and the hazards of personnel handling.

A carriage is used to move the part under test between the 2 chambers within few seconds. All comments will be collected and dispersed to the appropriate committee s.

JEDEC standards and publications are adopted without regard to whether or not their adoption may involve patents or articles, materials, or processes. JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, jesd22a106 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 jeec or internationally.

NOTE The worst-case indicator specimen location is identified during the periodic characterization of the worst-case load temperature. It is the most severe type of test of all the temperature related tests as it involves a high rate of change of temperature. The elapsed time measured from removal of the load from one bath until insertion in the other bath. Thermal shock is performed to determine the resistance of the part to sudden changes in temperature.
