Many military and/or aerospace designs require production lot testing of components in order to determine if the parts are quality compliant. These full-lot tests can be time consuming and expensive. For some applications, it is possible to instead perform a sample-size lot test, which tests a percentage of the components, to confirm the performance of parts before lot acceptance.
At Samtec, we now offer this sample-size lot screening, and it is primarily being used by our military and aerospace customers. Incorporating elements of MIL-DTL-55302 Group A, B, and C testing and qualification, Samtec is supporting those applications requiring additional and routine quality assurance.
This testing is specifically designed for how Samtec’s customers use our products, and the same number of products are tested each time. Each order includes a full test report.
Test Data
Test data captured includes insulation resistance (IR)/dielectric withstanding voltage (DWV), mating/unmating, and solderability—similar to what is required by MIL-STD-55302. Specific test reference documents include: EIA-364-23 (Low Level Contact Resistance Test Procedure for Electrical Connectors and Sockets), EIA-364-13E (Mating and Unmating Force Test Procedure for Electrical Connectors and Sockets), EIA-364-20 (Withstanding Voltage Test Procedure for Electrical Connectors), EIA-354-21 (Insulation Resistance Test Procedure for Electrical Connectors), and J-STD-002D, Method A (Solderability Test for Component Leads, Terminations, Lugs, Terminals, and Wires).

Getting Started with Sample-Size Lot Screen Testing
The process begins with a discussion between the customer and Samtec sales, a unique part number is assigned, and any additional requirements are defined. Sample-size lot screening averages about 33% of the cost and lead time of production lot testing.
Samtec only performs sample-size lot screening in-house, where all instruments and measuring equipment are calibrated to National Institute for Standards and Technology (NIST) traceable standards according to IS0 10012-l and ANSI/NCSL 2540-1, as applicable. Full-size lot testing requires the use of a third-party test house.
