11、zance CE-2.0 EIA Committee on National Connector Standards.) 1 Introduction 1.1 Scope This standard establishes a test method to expose connectors and sockets to extremes of high and low temperatures at a specified ramp up and ramp down rate. NOTE If the ramp time between temperature extremes is 2.0

12、 minutes, this test procedure shall not be used. The procedure as specified in EIA-364-32 (Thermal Shock (Temperature Cycling) Test Procedure for Electrical Connectors and Sockets) shall be performed as a substitute. 2 Test resources 2.1 Test equipment The chamber and accessories shall be constructe

13、d of material that will not be affected by the temperature extremes as specified. A suitable open screen tray, rack or other suitable holding feature shall be provided to ensure that the specimen shall be exposed to circulating air. Specimens shall not be subjected to radiant heat from chamber condi

14、tioning processes. The circulation of air within the chamber shall be sufficient to assure a no-load temperature uniformity of 5C. A temperature recorder and controller shall be provided, capable of controlling and recording the temperature within 2C at any setting throughout the temperature range.

15、3 Test specimen 3.1 Description A test specimen shall consist of a mated connector, unless otherwise specified in the referencing document. 3.2 Preparation 3.2.1 The test specimen shall be assembled with contacts and all accessories required for proper function of the specimen under test, unless oth

16、erwise specified in the referencing document. EIA/ECA-364-110 Page 2 3.2.2 The test specimen shall be tested in a terminated and mated state, unless otherwise specified in the referencing document. 3.2.3 When applicable the conductor lengths (directly terminated to the contacts or as attached to sup

17、port vehicles) shall be of sufficient length to interconnect the test specimen to applicable test equipment as may be specified for pre and post measurements or for monitoring during the test exposure. 3.2.4 If required, fixtures shall be lightweight with low thermal capacity in order to minimize “h

18、eat sink” effects. 4 Test procedure 4.1 Mounting The test specimens shall be placed in such a position with respect to the air stream so that there is substantially no obstruction to the flow of air across and around each specimen, unless otherwise specified in the referencing document. When special

19、 mounting is required it shall be specified in the referencing document. 4.2 Initial and final measurements The specified measurements shall be made prior to the first cycle at room ambient conditions, and after the last cycle after recovery to room ambient conditions, unless otherwise specified in

20、the referencing document. 4.3 Test cycle 4.3.1 The specimen shall be placed in the test chamber, as specified in 4.1, when the chamber is at room ambient (15 C to 35 C). 4.3.2 The specimen shall be cycled at the rates specified in the following manner: step a: ramp up to the high (hot) temperature l

21、evel, step b: dwell at the high (hot) temperature level, step c: ramp down to the low (cold) temperature level, step d: dwell at the low (cold) temperature level, step e: repeat steps a through d until the specified number of cycles has been completed, step f: return to room ambient as defined in 4.

22、3.1 at the same ramp rate used in step a. EIA/ECA-364-110 Page 3 4.4 Ramp rate 4.4.1 If necessary, based on the specified ramp rate (hot to cold) liquid nitrogen may be used. If used, liquid nitrogen shall be introduced in such a manner that it shall not be directed onto the test specimen. 4.4.2 Unl

23、ess otherwise specified in the referencing document, the ramp rate shall be an average of 5 C/minute. 4.4.3 A chamber temperature overshoot may be used to help achieve the desired test sample temperature. It shall not exceed 10 C on the cold side nor more than +10 C on the hot side. 4.4.4 Humidity s

24、hall be uncontrolled. 4.5 Dwell time 4.5.1 The temperature extremes shall be maintained within 3 C, with the exception of overshoot as noted in 4.4.3. 4.5.2 The minimum dwell time shall be 10 minutes after the specimen(s) has reached the chamber temperature specified, unless otherwise specified in t

25、he referencing document. This shall be determined by placing a thermocouple at the midpoint along the longitudinal length on the side of the test specimen. Only one specimen needs to be monitored located near the center of the group of specimens under test. 4.6 Unless otherwise specified in the refe

26、rencing document, the severity level and duration shall be in accordance with one of the conditions as indicated in table 1 and 2 respectively.
