1、JEDEC STANDARD Thermal Shock JESD22-A106B (Revision of JESD22-A106A, April 1995) JUNE 2004; REAFFIRMED: SEPTEMBER 2011 JEDEC SOLID STATE TECHNOLOGY ASSOCIATION NOTICE JEDEC standards and publications contain material that has been prepared, reviewed, and approved through the JEDEC Board of Directors

2、 level and subsequently reviewed and approved by the JEDEC legal counsel. 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

3、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 involv

4、e patents or articles, materials, or processes. By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC standards or publications. The information included in JEDEC standards and publications represents a sound

5、approach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or publication may be further processed and ultimately become an ANSI standard. No claims to be in conformanc

6、e with this standard may be made unless all requirements stated in the standard are met. Inquiries, comments, and suggestions relative to the content of this JEDEC standard or publication should be addressed to JEDEC at the address below, or refer to www.jedec.org under Standards and Documents for a

10、06B Page 1 Test Method A-106B (Revision of Test Method A-106-A) TEST METHOD A106B THERMAL SHOCK (From JEDEC Board Ballot JCB-04-57, formulated under the cognizance of the JC-14.1 Subcommittee on Reliability Test Methods for Packaged Devices.) 1 Scope This test is conducted to determine the resistanc

11、e of a part to sudden exposure to extreme changes in temperature and to the effect of alternate exposures to these extremes. 2 Terms and definitions dwell time: The total time the load is immersed in the bath. load: The specimens under test and the fixtures holding those specimens during test. NOTE

12、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. maximum load: The largest load for which the worst-case load temperature meets the timing requirements (see 4.1). monitoring sensor: Th

13、e 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. specimen: The device or individual pie

14、ce being tested. transfer time: The elapsed time measured from removal of the load from one bath until insertion in the other bath. worst-case load temperature: The temperature of a specific specimen as indicated by a thermocouple imbedded in the body and located at the center of the load. JEDEC Sta

The thermal capacity and liquid circulation must en

16、able the working zone and loads to meet the specified conditions and timing (see 4.1). Worst-case load temperature shall be continually monitored during test by indicators or recorders reading the monitoring sensor(s). The worst-case load temperature under maximum load conditions and configuration s
