CERTIFICATION
All instruments and measuring equipment were calibrated to National Institute for Standards and Technology (NIST)
traceable standards according to IS0 10012-l and ANSI/NCSL 2540-1, 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
1. Temperature Rise/Current Carrying Capacity
1.1. To determine the amount of current the device under test (DUT) can safely carry over the operating
temperature range of the DUT.
1.2. Contact loading will also be addressed in this document which will determine how much current can be
carried as the number of energized contacts is varied.
APPLICABLE DOCUMENTS
Standards: EIA Publication 364-70 Temperature Rise
EIA Publication 364-06 Contact Resistance
TLPM-032 Current Carrying Capacity
IEC 512-3 Electromechanical Components for Electronic Equipment: Basic Testing Procedures
and Measuring Methods, Part 3: Current Carrying Capacity Tests

All materials shall be manufactured in accordance with the applicable product specification.
All test samples shall be identified and encoded to maintain traceability throughout the test sequences.
After soldering, the parts to be used shall be cleaned according to TLWI-0001.
All samples shall be visually inspected and cleaned as necessary.
Any additional preparation shall be noted in the individual test sequences.
Solder Information: Lead Free
Re-Flow Time/Temp: See accompanying profile.
All products designed to operate mounted on a printed circuits board shall be tested mounted to test boards in
accordance with EIA-364-70.

TEMPERATURE RISE (Current Carrying Capacity, CCC):
1. Thermocouples shall be calibrated in accordance with Samtec documents; TLWI 0003, Thermocouple Welding
Procedure and TLWI 0005, Thermocouple Calibration
2. The thermocouples shall be placed at a location to sense the maximum temperature generated during testing.
3. Temperature stability shall be defined as the temperature at which three successive readings, 5 minutes apart,
differ not more than 1° C (computer controlled data acquisition). This is the Temperature Rise that the Current
Carrying Capacity and De-rating curves are based on.
4. The following loading configurations shall be tested (double for two row systems):
a) One contact energized only
b) Two contacts energized adjacent to each other
c) Three contacts energized adjacent to each other
d) Four contacts energized adjacent to each other
e) All contacts energized
5. The following loading configurations shall be tested for Temperature Rise/Current Carrying Capacity testing of
two row connector systems:
a) Two by One contact energized
b) Two by Two contacts energized adjacent to each other
c) Two by Three contacts energized adjacent to each other
d) Two by Four contacts energized adjacent to each other
e) All contacts energized
6. Three samples shall be tested for each of the above configurations for a total of eighteen assemblies.
7. Temperature Rise measurements shall be made at 5 different current levels yielding temperature rises in the 10 to
70C range.
8. The base curve for the Current Rating chart will be derived from the average (maximum) value of three test
specimens in accordance with IEC 512-3, Test 5b.
