1、JEDEC STANDARD Thermal Shock JESD22-A106B.01 (Minor Editorial Revision of JESD22-A106B, June 2004, Reaffirmed September 2011) NOVEMBER 2016 JEDEC SOLID STATE TECHNOLOGY ASSOCIATION NOTICE JEDEC standards and publications contain material that has been prepared, reviewed, and approved through the JED

2、EC Board of Directors 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 pro

3、ducts, 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 thei

4、r adoption may involve 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 publication

5、s represents a sound 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 claim

6、s to be in conformance 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 Standard

10、 Board Ballot JCB-04-57, and JCB-16-50, 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 resistance of a part to sudden exposure to extreme changes in temperature and to the effect of altern

11、ate 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 The maximum load is the maximum mass of specimens and fixtures that can be placed in the wor

12、king 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: The temperature sensor located and calibrated to indicate the same temperature as at the worst

13、-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 piece being tested. transfer time: The elapsed time measured from the complete removal of the l

14、oad from one bath until the full insertion in the other bath. worst-case load temperature: The temperature of a specific specimen as indicated by a thermocouple imbedded or attached to the body of the load and located at/near the center of the load. JEDEC Standard No. 22-A106B.01 Page 2 Test Method

15、A-106B.01 (Revision of Test Method A-106B) 3 Apparatus The bath(s) used shall be capable of providing and controlling the specified temperatures in the working zone(s) when the bath is loaded with a maximum load. The thermal capacity and liquid circulation must enable the working zone and loads to m

16、eet 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 shall be verified as needed to valida

17、te bath performance. Perfluorocarbons that meet the physical property requirements of Table 2 shall be used for conditions B, C, reworded to be consistent with Table 1. 2 Subclause 4.1, Timing 1stsentence; changed 10 seconds to 20 seconds. 2 Subclause 4.1, Timing 3rdsentence; reworded. 3 Clause 4 re

18、numbered to clasue 5 Standard Improvement Form JEDEC JESD22-A106B.01 The purpose of this form is to provide the Technical Committees of JEDEC with input from the industry regarding usage of the subject standard. Individuals or companies are invited to submit comments to JEDEC. All comments will be c
