7 PROJECT NO.: 96290D SPECIFICATION: EIA 364, TP _- --- ^ ~ PART NO.: BKT/BKS PART DESCRIPTION: Socket Contact -^ a _ _ SAMPLE SIZE: One TECHNICIAN: SR/RVO --_ START DATE: COMPLETE DATE: ROOM AMBIENT: 23 C RELATIVE HUMIDITY: 50% EQUIPMENT ID#: 25, 250, 410, 440, 536, 580 _ ^_ CURRENT CARRYING CAPACITY PURPOSE:.- To establish the current carrying capacity of the test sample under evaluation. This is achieved by determining the temperature rise resulting at the contact interface at specified current levels. The temperature rise at a given current level plus the ambient operating temperature should not exceed the temperature rating of the test sample. Thus, the current rating of the system decreases as the operating ambient increases. This data can also be used to determine potential local "hot spots" internal to the test sample, possible degradation factors, thermal effects on adjacent areas and/or the acceptability for use of pulsing. techniques _---_ PROCEDURE: 1. The test was performed in accordance with EIA 364, TP Test Conditions: a) Current Levels : 1,2,3 amps b) No. of Contacts in Series : Five c) Derating Curve : Yes d) Termination : Solder 3. The test samples were prepared to accept thermocouples at the appropriate locations. 4. The T-Rise was monitored on the middle position of the five contacts in series. 5 Contech Research

8 PROCEDURE: Continued An additional thermocouple was placed 2" outside of the test samples adjacent to the locations to be monitored. This is accomplished to evaluate the impact of ambient conditions. The thermocouples were attached to a data acquisition/ scanner system which in turn was interconnected to a plotter. The test specimen was placed in a chamber or room which prevents air currents and the like, influencing the observations. The current level indicated was applied until temperature stabilization was reached. Temperature stabilization is defined as no change in T-Rise greater than f l C over a 15 minute interval ^ REQUIREMENTS: The temperature rise shall be measured and recorded and a current derating curve established. _ RESULTS: 1. Figures #Ol thru 03 indicates the temperature rise characteristics at 1, 2 and 3 amps. The following is a summary of the data shown on these plots: currentlexel TEMPERATURE RISE 1 C) 1.0 amp amp amp The derating curve is evaluated with a maximum connector operating temperature of 105 C. The base curve is created by the data from Figures 01 thru 03. The derated curve is 20% from the base curve. 3. The current carrying capacity is defined as the operating ambient (equipment) plus the T-Rise shall not exceed the maximum connector operating temperature. 6. Contech Research
