Electronics verification testing, first article testing, qualification testing, environmental stress screening( ESS), EMI testing, and factory acceptance testing – all performed in accordance with industry standards such as MIL-STD-810, MIL-STD-461, and IPC test methods.
As part of Sechan’ s Engineering department, program engineers and test technicians perform routine and specialized testing using an extensive array of calibrated semi-automated and automated test equipment. Circuit card assemblies are inspected with AOI / AXI systems and tested using flying probe and in-circuit testing. Wiring harnesses and cables are tested with Cirrus equipment. Subassemblies undergo testing at each stage prior to upper level integration into box builds, where they are typically subjected to ESS and final acceptance testing or ambient acceptance testing. Most subassemblies are tested using program-specific test sets developed to meet customer requirements, with full documentation traceability and customer certification before deployment. Environmental stress screening is conducted in Sechan’ s 5,000-square-foot ESS lab, which features multiple temperature chambers, vibration tables, an anechoic chamber, and other specialized test equipment, all operated in compliance with MIL-STD-810 standards.
The complex solutions Sechan designs, manufactures, tests, and delivers are typically fielded for decades and require ongoing maintenance, repair, and overhaul. Sechan’ s Product Sustainment team – comprising engineers, test technicians, and crosstrained assembly technicians – specializes in troubleshooting equipment and collaborating with customers to develop effective repair or upgrade solutions.
