2 /TMMH CERTIFICATION All instruments and measuring equipment were calibrated to National Institute for Standards and Technology (NIST) traceable standards according to IS and ANSI/NCSL , as applicable. 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: Test to current ELP test plan for 100, 250, 500, and 1,000 cycles. Process with leaded paste to PCB TST-XX. APPLICABLE DOCUMENTS Standards: EIA Publication 364 TEST SAMPLES AND PREPARATION 1) All materials were manufactured in accordance with the applicable product specification. 2) All test samples were identified and encoded to maintain traceability throughout the test sequences. 3) After soldering, the parts to be used for LLCR and DWV/IR testing were cleaned according to TLWI ) Either an automated cleaning procedure or an ultrasonic cleaning procedure may be used. 5) The automated procedure is used with aqueous compatible soldering materials. 6) Parts not intended for testing LLCR and DWV/IR are visually inspected and cleaned if necessary. 7) Any additional preparation will be noted in the individual test sequences. 8) Solder Information: Lead 9) Re-Flow Time/Temp: See accompanying profile. 10) Samtec Test PCBs used: PCB TST-XX Page 2 of 19

5 ATTRIBUTE DEFINITIONS The following is a brief, simplified description of attributes. THERMAL: 1) EIA , Temperature Life with or without Electrical Load Test Procedure for Electrical Connectors. 2) Test Condition 4 at 105 C. 3) Test Time Condition B for 250 hours. 4) All test samples are pre-conditioned at ambient. 5) All test samples are exposed to environmental stressing in the mated condition. HUMIDITY: 1) Reference document: EIA , Humidity Test Procedure for Electrical Connectors. 2) Test Condition B, 240 Hours. 3) Method III, +25 C to + 65 C, 90% to 98% Relative Humidity excluding sub-cycles 7a and 7b. 4) All samples are pre-conditioned at ambient. 5) All test samples are exposed to environmental stressing in the mated condition. LLCR: 1) EIA , Low Level Contact Resistance Test Procedure for Electrical Connectors and Sockets. 2) A computer program, LLCR 221.exe, ensures repeatability for data acquisition. 3) The following guidelines are used to categorize the changes in LLCR as a result from stressing a. <= +5.0 mohms: Stable b to mohms: Minor c to mohms: Acceptable d to mohms: Marginal e to mohms: Unstable f. >+2000 mohms: Open Failure Page 5 of 19
