All contents contained herein are the property of Samtec. No portion of this report, in part or in full shall be reproduced without prior written approval of Samtec. SCOPE To perform the following tests: Design verification test. See test plan. APPLICABLE DOCUMENTS Standards: EIA Publication 364 TEST SAMPLES AND PREPARATION 1) 2) 3) 4) All materials were manufactured in accordance with the applicable product specification. All test samples were identified and encoded to maintain traceability throughout the test sequences. Either an automated cleaning procedure or an ultrasonic cleaning procedure may be used. The automated procedure is used with aqueous compatible soldering materials. 5) Any additional preparation will be noted in the individual test sequences.

TEMPERATURE RISE (Current Carrying Capacity, CCC): 1) EIA-364-70, Temperature Rise versus Current Test Procedure for Electrical Connectors and Sockets. 2 2) When current passes through a contact, the temperature of the contact increases as a result of I R (resistive) heating. 3) The number of contacts being investigated plays a significant part in power dissipation and therefore temperature rise. 4) The size of the temperature probe can affect the measured temperature. 5) Copper traces on PC boards will contribute to temperature rise: a. Self heating (resistive) b. Reduction in heat sink capacity affecting the heated contacts 6) A de-rating curve, usually 20%, is calculated. 7) Calculated de-rated currents at three temperature points are reported: a. Ambient о b. 80 C о c. 95 C о d. 115 C 8) Typically, neighboring contacts (in close proximity to maximize heat build up) are energized. 9) The thermocouple (or temperature measuring probe) will be positioned at a location to sense the maximum temperature in the vicinity of the heat generation area. 10) A computer program, TR 803.exe, ensures accurate stability for data acquisition. 11) Hook-up wire cross section is larger than the cross section of any connector leads/PC board traces, jumpers, etc. 12) Hook-up wire length is longer than the minimum specified in the referencing standard.
